My 1/10 scale did start eventually, but my 1/8th never even popped once. My 1/10 scale after I pull on it for a while will spit gas out the stinger even if it hasn't started. Is this the same with 1/8 engines? Mine iddn't even have a drop on the tuned pipe even when I tilted it nothing came out and that seem very odd to me for as much as I tried to start it. I checked the high speed needle and it's correct, but I don't have any base settings for any of the other needles as they sad they should be set from the factory.
