Couple of things to do:
1) Add a thin copper shim on the engine to reduce compression a bit and make break in easier
2) Loosen the plug 1/2 turn or so, get it fired up, then tighten it back down
3) Get a 14.8 V lipo battery..a lot more ass to start the engine
4) Get the Ofna Truggy Box with a 14.8V Lipo and you can start any engine out there...it spins my new Novas and GRP's over like nothing
