Is it normal for these engines to be very cold natured on start up? I have a race prep in my truggy with the 086 pipe, P4 plug, EB Mods 30% fuel and it takes at least three or four starting attempts for this engine to actually run. It will fire up and run for a few seconds and cut off. I literally have to start trying to start the engine halfway through the previous race just so it will run when my race is up.

Never had any of these issues with my Ninja JX.21 engines. Ideas?
