I'm beginning to understand why there are those who prefer electric RCs. With my electrics I head out to a spot fully expecting to run my RCs for a bit. And for the vast majority of the time that's exactly what happens. Now with my Vekta.5 it's more like "let's just go out and see if it starts", because on any given outing it's just as likely to not start as to start. That was until the last two weekends when I have not be able to start it at all. Maybe someone here can provide some advice as to what I'm doing wrong.
My setup is a Vekta.5 with an OBR G340 full mod engine, 990 carburetor, and dominator pipe. The engine is about 7 months old with just over a gallon of fuel through it. To start it I generally add fuel, checking to make sure the hole in the fuel cap is not blocked. Then I press the primer bulb until it's filled and make sure there is fuel going through the return line to the tank. I pull the pull cord slowly about 3 times. Then I power up the transmitter and check to make sure the Super Bee kill switch is deactivated on the transmitter. Next power up the Vekta and listen for the Super Bee which will chime a few times and then go silent if all is well. Now I start to pull the pullstart to fire up the engine. If I have not messed with for a day or so it May Fire up for a few seconds before cutting off (even if I'm giving it throttle on the transmitter). Once it cuts off I can not restart at all.
I tried resetting the carbon needles to default settings (1 1/8 low and 1 5/8 high). I also tired adjusting the low needle 1/8 leaner then 1/8 richer. I bumped up the idle screw to almost maximum. I replaced the spark plug and added fresh fuel (93 octane mixed 28:1 with Castor 927) and retried everything above. I tried loosening the gas cap. I inserted a spark tester between the coil wire and the plug and verified there was spark. I thought maybe I flooded it. I turned it upside down with the spark plug removed and pulled the pull start a handful of times, then re-added the plug and tried to start it. I removed the carbon completely and tried to start it. I added a squirt of sure start into the engine with carburetor removed and tried to start it. So far nothing has worked. I haven't checked compression but I don't really know how yet.
If anyone has any ideas I would greatly appreciate it.
