Ok I switched glow plugs and it was about 60 here today vs. 30-35 yesterday and it started right up. First tank i let it idle through with no problems then heat cycled and second tank ran it up and down my street blipping throttle to about half. Third tanks started having some problems, it would die as soon as I hit the throttle, but idle fine. I did change a few screw setting around because it wasn't sounding right. It was hesitating and sounded like backfiring a bit, not sure though. Anyway how can you tell where the closed point is on this carb? I try to close it but it just gets harder to turn and never really stops like it's closed. I don't push it too far because I'm scared I'm stripping it. I was in a park today and man these are louder than 1/10 scales! I did run it in short grass a few times just to get a preview of how great it goes off road compared to my 1/10 scale, although it didn't seem as powerful. Hopefully thats just because I don't have it tuned right and not fully broken in yet. Can I take it full throttle yet, I'm on about my 4th tank which on the violator is a lot considering it's 140cc's each tank.
