Hello all, ok, I've searched every thread that I can get my eyes on and I can't find the answer to this question. I have a Mcculloch/Troy Built 25cc leaf blower engine that I converted for a Sig Rascal 110, I'm running a Zama 10mm carb with a Zenoah carb adapter, velocity stack and header pipe for a G-26. everything fits and runs like a dream until I line up (nose slightly down) for a landing, then the engine stalls..... DEADSTICK. No matter what I try, it will not idle with nose down attitude (not nose straight down, anything less than horizontal). I thought it might be my tank placement but since it's a pumper carb that shouldn't matter (at least in my head) I tried the original carb but with the mods to it, it won't give it enough fuel to transition. At first I suspected I was just running it out of fuel as if the clunk was dry. it does it full tank or partially full. I am one more deadstick away from buying a Zenoah and a new plane but I hate to spend the money on a plane I already have. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11[]
