Need more compression!
Alright, I just purchased a GS Storm RTR (my first ever nitro car) and it is not starting the way it should. Everything else is working fine: the main needle is 3 turns out, the air filter is oiled, the glow starter ignites the glow plug, the carburetor is primed and the pull start is alright. However, I can easily turn the flywheel with my thumb, obviously meaning I am lacking compression. What are some options I can do to my buggy to increase the compression?
