The idle screw is all the way in, it won't even run there. the barrel has to be half or more to run this evening I got it to run at full throttle and I sat it on the ground and it would die.
So I got it running at full throttle again tuned the high needle for max speed (wheels turning in air), sat it down again and it took off crashed into the neigbors house and then drove itself into the river. After being submerged about 20 minutes I fished it out dried if off and fired it up again.
Took the throttle linkage off and fired it up just using my fingers to move the barrel it would start at full throttle and I kept richening the low trying to get rpms lower until the lsn is all the way out. Seems like the low needle is broken but it looks fine.
I am very familiar with nitro airplane engines and feel comfortable I can tune a car if I could just get it running.
