Jim When the fuel vent is blocked the carb fuel bowl level will be lowered and cause the engine to run lean.Carb heat could be acting like a choke by reducing ram air inflow, which would reduce the

Dick as well as fitting a short up - facing vent I have an electric in - line fuel pump. It is important to choose a pump that will free flow when switched off.I am using FuelFlow brand which is good

Thanks Mike, Kevin, I knew someone had the fuel flow info and Mike Dwyer is right about checking the fuel system for leaks. A blown up baloon on the vent tube works well to detect leaks. Jim P

I have a friend looking for Q-1 plans and templates. Isn't someone selling a CD of this? Larry

I changed over and added a "boost pump". Too many close calls like yours! I also had a fuel starvation engine "hiccup" probably caused by a cracked main fuel filler cap. Larry

Jim: The fuel flow requirement for gravity feed systems is 150% greater than "Takeoff fuel consumption of the engine." (FAR 23.995) (my source is old, may be renumbered, but I doubt the

Weather looks like it is going to cooperate quite nicely again this year for the Mountain States Canard Wing Fly-In and Engine Show in two weeks. http://www.MountainStatesFly-In.com/ We have NO

Kevin: How big of a syringe can you find? You don't really need to know how much the arrangement as is will/might generate. You need to know if doing so can recreate your problem. Kevin Fortin

Sam and gang, I have to admit, thinking that I scared the hell out of myself because I didn't tighten the gas cap properly is a bit annoying but at this point, this line of thinking is making the

Mark, That sparks some interesting testing ideas. Let me do a bit of math and see what kind of vacuum 120/140 mph (in Denver) represents, then I can guess if I can make a "constant vacuum" supply

Kevin, This phenomena of the low pressure air leaking into the fuel system is well documented. In fact, that was my first thought when I read your e-mail. Naturally all the gascolator foes come out

Bruce, I did check the mixture travel a week or so before flight and it was good so I am thinking it is OK. Kevin BTW Wit ur werld travls I wud think that U wud no how 2 spel egekated.... Huked on

kevin: Can you rig up a vacumn to the gas filler to try to replicate the apparent lose of fuel flow? measure the vacumn? Mark Kevin Fortin wrote:

Denver is at 5000' msl. Leaning out is a must especially in hot weather. I don't think just leaning out a bit is going to cause what you described. Is the mixture cable moving to full rich when the

I landed N96BJ on a 2500' grass strip on Sunday with plenty of runway remaining. Only minimal braking required. I actually had to add power to get to the end where the EAA meeting was held. During

Jim, Thanks for your response. Answers to your questions below: Question "3" The feed line is about 9" to 10" and looks like it is best path or damn close to it. I don't think you could shorten it

Paul and gang, Aside from the engine friction issue, Paul, you may have something here with the fuel cap. Mine is not vented, but, after the fact, I found that it was not tightened particularly well.
