Ross, it is normal with Facet fuel pumps to tick at about two ticks per second even if the engine is stopped. They tick faster when pumping up an empty float bowl, etc. As for running the same floatless carb on the same engine with gravity feed from the header, or under pump pressure from the wing tanks, I'd be skeptical. It seems like once it was set up for low pressure gravity feed running from the header and then you gave it 8x the pressure from the pump, it can't help but run richer. I'd think Ellision would know for sure though. Maybe I didn't fully understand how you had it set up though...

My plans were to run from wing tanks primarily, and only use the header as a reserve... so in that case, I could end up running too lean or not at all of the header. This is one of the things I wanted to tinker with this month. Today I pulled off the carb heat box and was able to spray engine starting fluid directly into the throttle body. Engine starts right up runs a bit then quits. I also played with starting using my primer circuit. I was able to confirm that priming initially is rich, then the engine kicks in. I was able to inject more primer shots, and keep the engine running, so I pretty much confirmed no fuel coming from the throttle body. I called and talked to Ellison today and asked if there was anything I could do short of shipping the carb to them. Ben indicated I can attach an air pressure source to the carb fuel inlet, and gradually raise the pressure to 20-25psi which should unstick the fuel valve. I've squirted some carb cleaner in the fuel inlet and am letting it soak while I run some errands,and take my daughter to the doctors. Hopefully I can get the fittings I need today to try and clear the carb. -- Ross 11/19/2001 12:16:36 PM, "Mark Langford" wrote: >RossY wrote: > >> The R Fuel pump is delivering fuel with no problem, however I >> suspect a slight air leak in the suction side of the line someplace >> as the pump never quite stops clicking. > >Ross, it is normal with Facet fuel pumps to tick at about two ticks per >second even if the engine is stopped.

I have had my air compressor for about 21 years now and the only problem I have ever had with it is, the low part of the bottom rusted out from water pooling up inside and not being drained. I had a local welder put a quarter inch 4130 patch on the hole and all is well now. The patch was fitted with a high pressure drain valve prior to being welded on. Now I can drain it after each use. This is recommended even more that once a month.

I called Ellison and discussed my suspicisions that my EFS-2 may be clogged up with varnish and asked if there was anything I could do to clean it up. Ben at Ellison suggested that I attach an air source and gradually bring the pressure up to 20-25psi. It should un-stick the fuel valve. Of course even though I have the day off, there are family things to do, so I had to take time to do those things. However I just got back from the shop where I was able to clear the blockage. I had soked the fuel inlet with carb cleaner fluid, then attached an air hose. Now I'm getting carb cleaner out of the metering tube! Yes!

Although Bob took down the site he used to have up, you can still find much of his writing on rebuilding, converting, caring for, selecting, maintaining, and just learning about VW engines, over on the Jeanie's Teenie/Teenie Two discussion group site. It's at http://www.network54.com/Hide/Forum/40291 And you have to wade down through the archives, but if you're just looking for Hoover's stuff, it won't take long. About 2 years or 18 months ago you should hit the series he did on rebuilds, but there is also much good info in and among the rest of the Teenie posts. Just look for his name by the post and subject. The man knows his VWs. And as long as I have the podium, I would like to apologize if it sounded like I was giving anybody "both barrels" (as in Ross and the KRNet.org website). I consider Ross to be a personal friend, and he has gone out of his way to help me out since I first got started thinking about building a KR. He's handed out free KR goodies, made up some great KRNet decals, created and maintained the website, handled the admin tasks (including wading through 1000's of posts after being on vacation for a couple of days)... all while supporting a family and trying to hold down a job that involved tons of commuting and being on the road. Oh, and while trying to build an airplane, too. So I had no intention of slamming Ross, only of voicing my opinion on what I look for when I hit a site where I'm looking for something. I've bumped my head against the Rand-Robinson "stuck in the 60's" low-tech way of doing business, so in this case any website is a far sight better than what Rand-Robinson has to offer! I understand and have worked with Jeanette Rand's "do it by hand, mail it by postal service, and call me on the phone when I'm there" way of doing business; nothing wrong with that. But nowadays expectations are much higher for being able to reach somebody who is in business by email, fax, or online ordering. That being the case, my idea is to make it as convenient and as informative as we can. I just get a little impatient with crawling banners, pop-up screens, and melting fades- but hey, I turned 50 this year so I think I'm entitled to start getting a little cranky. You younger guys with the desire and know-how to go for the more exciting programming- more power to ya! For me, just give me some clear information, crisp photos, and easy-to-find info and I'll be happy. Just my 2 cents worth, and sorry if I caused a problem.

The reports I've seen are that it causes more problems than it solves. Guys have had gummy residue in their stainers, plus little granules of sloshing stuff trapped in filters, gascolators, and so forth. A well-made fiberglass tank shouldn't give problems if the corners and places where fittings are cut in are well-reinforced and epoxied extra-heavily.

Message-Id: <20011120203814.TOAF1305.femail1.sdc1.sfba.home.com@cx239334-a> Went out with a newly cleaned up Ellison carb, and viola! Starts and runs! It's running way too rich, but this is be due to my previous work to enrichen the mixture with the mixture adjust screw. I tightened it up a few turns and played with various priming start procedures. The engine starts OK on the two cylinder primer after a few cranks, but shooting starter fluid into the throat is the best method. As a result, I re located my primer circuit from two fittings at #1 and #3 cyl to one fitting at the carb plenum area of the intake manifold, just behind the carb. I tapped for a 1/8" fitting, but as the tubing walls are thin, I'm using some JB weld as well to make sure it doesn't come loose. I'll try it out tomorrow. In the meantime I've got some indicated temps from a couple of 15 minute runs. 275deg CHT #3 cyl (right rear) 900deg EGT #3 cyl (right rear) 110deg Oil (sender in bot of sump -- expect to read cool) Oil pressure 25psi idle to 48psi at 2000 rpm I validated that the alternator is functional as the voltage is about 12.5-13V indicated, but drops to 11.5V when the alternator bus breaker is pulled. I don't have a magneto, I'm using a Compu-Fire electronic ignition with a bosch 009 as my primary, so I was a bit disturbed when the engine quits after the master switch is opened. The alternator is supposed to provide enough current to keep things going, and I thought this was validated on earlier trials... I'll have to check my notes from before, and also check my schematic and wiring. I validated that I could successfully start the engine with both fuel pump and header tank fuel pressures. As I said earlier, I was running way too rich. Mixture full lean at 1000 rpm, and it would idle forever. I decieded to experiment and switched from gravity feed header tank to right fuel pump tank, then cut the right fuel pump. It kept running, and in fact seemed to lean out pretty good. I was going to stopwatch this, but decided to add some throttle, still with no fuel pump and it died. Since I've moved the timing around a bit, I'm preparing to re-check the timing again tomorrow. Unfortunatly, I can't locate a timing mark on the block, so I have to go back through identifying TDC again. This time I hope to make a better mark. I've pulled the prop since this makes timing easier, and allows me to fix the hangar rash from the Oregon move. My old spinner was dented, and some holes elongated as a result, so I have a new spinner bowl which needs to be cut and drilled. By the way... having the forward deck removable makes it a snap to re-route things like primer lines through the firewall. I have a fuel shuttoff valve, and two quick disconnects for the sight gauge (top/bottom). All are working great and no fuel leaks! Woo Hoo! If all goes well, I should be starting some low speed taxi tests this week with the cowling on, and starting to gather some excel spreadsheet data on engine temps/pressure. I'll post it on my website later. Oh by the way... if anyone knows where to find wood prop torque data post it. I think I found it in Tony Bengelis book, but Im not sure... I'll be looking for that next. -- Regards Ross Youngblood rossy65@home.com ------------------------------ Date: Tue, 20 Nov 2001 17:26:56 -0500 To: , From: "Daniel Heath" Subject: Re: KR> Progress!

Message-Id: <20011120232942.BMQN7873.femail12.sdc1.sfba.home.com@cx239334-a> Dan, Thanks for the post... My guess was that once the system is primed, the intake vacuum must be enough to keep on drawing fuel in. This plus the mass of the fuel in the 3/8" line. In my case, I'm not sure it would run in a climb, or respond well to an abrupt change in power settings, but it's nice to know the fuel is flowing well. But thats why I'm planning to spend this month playing around taxi testing to find out these things. -- Ross -- Ross 11/20/2001 3:52:58 PM, "Daniel Heath" wrote: >Just a FYI here.
