Just check how many shims are installed in the engine -
the stock shims are for 30% nitro. if you run 16% you need to take out the cooper shim which is 0.2mm the aluminium shim is 0.3mm.
Yeah be great to have you up. I hope to have new car/engine ready for this w/end racing. (opps been very slack on the r/c photo gallery of late!)
BTW - I thought smoke is good as long as u got power
