RE: Extreme Flight 87" Yak 54 - Build & Fly
Chip will- try this:
works on any gasser when cold -first start of the day.
Open throttle close choke flipover until it starts to feel wet - typically 5-20 flips -depending on needle settings and simply sometimes just difference in engines.
Now - open choke - flip a few more times
Now - close throttle to med idle - engage spark - flip -should start first flip.
My 50 starts instantly anytime
I use 32-1 Mobil 1 oil (MX2t)-and 91 oct fuel -(on all engines)
