My concern is that if I lock it down and then need to react to a situation, I won't be able to. See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt.

Most throttle plates are made with a slight bias towards the bottom, or closing direction, so that the engine will suck the throttle plate against the throttle stop screw allowing it to hold an idle consistently. If not you would have to actually move it back to idle, or any other position always. The Lycomings I flew would suck the throttle shut gradually while running if some amount of friction lock was not used. We would always set it so that there was just enough tension to hold the throttle in place but allow for changes to be made if needed or desired. Be glad you do not have my carb; I have to ADD a spring to counter the throttle return spring so that mine will stay put where I open it to or it will behave like it does in the car and return to idle whenever I am not holding the throttle! LOL I will also add some friction at the throttle quadrant for holding it in one place, but allowing for adjustments...

I was also in a steep left turn that may have helped the oil to the tube in the crank case.

I know that others have had this cable and removed it. I feel just the opposite. At idle I can give it a turn or 2 to adjust idle and the push button lock seems completely natural to me and has from the start. I don't ever think about having to push the button it just happens. I may have a throttle that wants to close also and just don't know it. Joe On Tue, 20 Dec 2005 17:42:21 -0500 (Eastern Standard Time) "Dan Heath" writes: > For Aero Carb users.

Joe Horton, Coopersburg, PA. joe.kr2s.builder@juno.com Hi Joe, Glad to hear you and your plane are ok. I was wondering if an air tight seal along the top and perhaps the sides of the cowling would have prevented, or reduced the amount of oil that came up on the canopy. I'm just thinking out loud. I don'tknow how you constructed your cowling.

The slide rides on Delrin gaskets. That makes it as slick as owl shit (that is a southern saying for those who have never heard it). Therefor if you leave the friction lock loose, the suction along with the vibration of the engine will cause the slide to close on the Aerocarb. Mine would do it also but very slowly. You do not have to completely lock down the cable but apply enough friction that you can move it yet it will not move on it's own. You should be ok and you will get used to the friction lock very quickly. It eventually will become second nature to you.

Joe Horton ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Make sure you have no "low points" in any of your crankcase vent lines. What I mean is that there should be no low spot in the tube between any two mounting points. Any condensation in the tube can collect and build up in these low points and eventually close the tube entirely when frozen. If a crankcase vent tube rises vertically from the engine, continue the rise to the high point and then a continual decent to the exit. Hopefully any condensation will either run back to the crankcase or exit the tube. Also, make sure you use large enough diameter lines so that drops of moisture collecting on opposite walls can't bridge over. I had a clear vent tube for about the first 50 hours of flight time and I was amazed at the crap I saw in it. Also, unless you have a large rigid line, it doesn't hurt to take a spring of sufficient size, stretch it to a considerable length, then insert it inside the tube so the line won't collapse. I seem to recall hearing of aircraft engines that had lines freeze and blow seals but I don't recall any of the details.

Lanford your flying the wings off that thing. I bought my KR2 from my father who owned it for 17 years and never flew it. I worked on it for 2 1/2 years (really 1 1/2). It flew and I did have my challenges. Wrong prop, hard landing, and a fuel leak. With all of that said, one of the other reasons I wanted the plane was to have fun and travel, mostly for fun. It has helped me more for work. I travel to Yuma AZ 2 or 3 times a month for work. These days my wife would dred, after driving for 3 hours there and 3 hours home plus all the driving while there, I would come home whipped. Now I can fly there, do my work, fly home and be able to function when I get home, go to a dinner and a movie last Friday for example. The summer here is pretty hot, so flying is done in the AM. This time of year is our good time to fly. I will be posting more photos on my web page when I get them. Due to having the retracts on my plane I have been getting a draft in the cockpit and I have had to start wearing Jeans, and I may have to put a glove on my right hand. The cold air runs up the stick and is annoying. I remember last year of seeing E-mails that said there time for buildingand time for flying. Get the building done because there is a lot of time for flying. COME FLY WITH US.

I would also recommend that you install a spring which will pull the throttle to something close to full if the cable becomes disconnected. If and when the cable comes loose, you want to stay in the air until you are ready to shut off the mixture and land.
