RE: Seagull Spacewalker II 120 Arf
Engine trouble update:
Finally got around to running the engine yesterday after tightening everything. After a bit of adjustment it's running well but, it won't drop back to idle after going to full throttle for about 30 secs. When I pull the throttle back to idle, the rpm will not come down below 3300 rpm. If Iblip the throttle a couple of times the rpm will drop down to around 1800 to 2000. I can't find anything binding or sticking so, I'm assuming the carb has a problem.
The adjustments aren't right either although, it's running OK. I've opened the "high" end needle more than 1 full turn (rich)to get it to peak and closed the "low" end needle (lean) almost 1 full turn to eliminate most of the 4 stroking. The transition is fine. If it weren't for the idle problem I'd fly it like this but, half throttle landings are not good.
Looks like I'll be installing a new carb. Idon't think a rebuild is the solution.
