I'm not to sure about that one. Does the truck try to start at all? Maybe the sleave is in wrong? I think that these engines always have a free flow to them like a dirtbike.

I use os#8 plugs and byrons 30% nitro and most of the time she starts in a few pulls. When I first broke my truck in I think I gave the LSN a 1/4 turn to the left(don't think that you should follow that path tho). Opened the carb using the trim on the controler by +15 or something close to that and slowly turned that down as the engine freed up from running. I also primed the carb with my finger on the exhaust port and gave her 3 short/slow pulls. Put my glow starter on and pulled hard strait out letting the motor give 2 pops.


Inportant break in tip!!!
Just crack the glow plug a tiny bit before you put the glow starter on and tighten right after she starts.

think I got it all out...
