As this is the only carb I've ever felt I understood, I have one on a top mounted manifold on my 1641cc engine. I have yet to test run the engine, but I have full confidence in the carb! The SU is well supported in terms of available jetting, spare parts, books, etc. All those Mini owners can't be wrong! (If I ever loose my medical I'm going to buy a 1275cc Austin Cooper S and go out and turn square corners).

Every one seems to widen and lengthen theirs, (KR-2's). Build a mockup for size and see what you think. I wished I had done that first, I would have widened it at least 4" and maybe even lengthened it by one bay.

I did not counterbalance mine and have my VNE set at 195 mph. I also did flutter testing to that speed to verify that it was not a problem on my KR. If you plan to go faster, I would highly recommend mass balancing your elevator.

My thought is that you have no way of verifying the measurements in you notes will give you the degree of deflection called for in the plans. ERASE THE NOTE. Use a degree meter ( $5.00 ) or a smart level to get the deflection called for in the plans. This measurement may have come from a flying aircraft but that doesn't mean it's correct. Assume all information to be wrong until proven correct.

I was trying to get a good debate going on the pros and cons. Myself, I have always preheated engine and cockpit when the temp gets into the mid teens. The radios and instruments also need to be warmed. About 15yrs back I rigged up a heater using a hair dryer and 4ft of SCAT. Most hair dryers put out 1500 watts and move a lot of air. I was able to heat the engine of my C175 in less than an hour with the temp in the low teens. Oh well, I guess you folks are getting smarter all the time. That's what happens when you spend time on the KR Net. But I still can't keep my engine warm enough when the air temp is below 20deg. Flew yesterday, air temp was 28deg, and held 180 to 190 on the oil. I give up. When the temp is below 20, I'll just have to stay in the shop and work on the twin.

The plans never called for it, and lots fly without the counterbalanace. With that said, people are adding and flying with counterbalance. Most are tip weights and some are internal.

The engine is back together and running fine. In the process of working on the engine and reading what you had to say, I went over the entire engine installation. The one thing that didn't add up was where the oil cooler is located, where it was when I bought the plane, on the baffle behind #3 cylinder head. I thought this was where it was supposed to be. Keep in mind my "2" was already built when I got it. Even with doing a rebuild on it [new eng, new elec,IFR, moved control stick to left center, wing tanks, strobes, ants, ect.] I hadn't ever seen a KR before [except for pictures] and had no plans to go buy. So I left it there and went by what I had learned over 25yrs of working on aircraft with the rest. Looking at the production birds, you find the oil coolers are mostly either up front at the air inlet or mounted on the firewall with air ducted to it from the aft baffles. But something sticks in my mind that Beech put the cooler on the aft baffle in the T34. Dana, you may be able to shed some light on this. Where is the cooler on your beech? So I got all the books out once more and dug up all I could find that delt with oil cooling. Seems that the norm is firewall or cowl inlet. And the new winning location will be - firewall, same setup as on the Piper Cherokees. And if that doesn't work, I think a turbine is the next test subject. That is the latest up date on the engine problems. Hope someone can benefit from this information. Thanks again for all the impute. PS: I made my reservations for"Barkleykosh" and plan to arrive on Thursday afternoon with my "2".

Where is the cooler on your beech? >> My oil cooler also doubles as an oil reservoir. It is located on the aft pilot side of the engine. Air is "ducted" to the cooler by way of the cowl baffling. The cowl flaps are located on the aft most position on the nose bowl. On a KR, you would need to make sure adequate air flow is getting to the cooler if you are going to mount it on the firewall. Remember, with baffling you are trying to make that air flow down through the fins of the cylinders. It may be so well baffled that no air is reaching aft, thus cowl flaps. I have seen cowl flaps on KRs. My oil cooler is mounted on the top of the case on the KR. Speaking of air flow, make sure you run an air hose to your gasculator(sp). Very important.

My Mooney has its oil cooler on the lower left front side of the engine cowling below the engine. The cooler is bolted to some brackets that are riveted to the cowling and that puts the cooler right up front in clean, cool, propblast air.

He reports that about the only difference in flying characteristics is that the KR-1 has more sensitive ailerons. I haven't flown the -2 but I've owned and flown two different KR-1s. The first one cruised at about 150 mph with an 1835 cc VW. The second cruises at about 130 mph with a 1700 cc VW. The only thing I would have preferred was an additional inch or two width at the pilot's shoulders.
