Took the pullstart off, and it is fine. I got a bit worried at that point, as it indicated something was up with the engine. However, I thought I would take the hair dryer to it and see if I can get it warmed up a little. Did that, and I could then pull the starter. Still lots of unburnt fuel coming out the exhaust, must have been running seriously rich! I think that, combined with the fact that when cold it is hard to pullstart anyway, must have caused that problem!

I think this little problem has convinced me to go the down the line of a starterbox. I will probably need one in the long run if I get a 1/8 car....

Anyway, thanks for your help 46u. Once again yet another problem adds to building up experience with Nitro engines!
