Hey Guy's
I have been flying my SPE 40cc for a while now and I have been quite happy with it using the stock Melody ingition unit. It provides plenty of power to get my 14Lbs Fw-190 around spinning a 18x8 3 blade prop at 6480rpm.
Anyways she has not flown for about 5-6 months after she was involved in a landing incident. I could be bothered fixing her[X(], but i have finally completed the repairs and fired the engine up today just to make sure it was all good. My SPE has always been a bit of a biter on start up, and today was no different. she also shakes the crap out of the model and the ailerons cop abuse because of it. On running her today i decided to take the cowl off and see if i could get it to run properly at WOT, because she has always misses or 4 strokes just a tiny bit.
Having stumbled on this thread again yesterday i read that all these symptoms are an indicator that the timing was out. So following all the links and instructions i found that mine too had been delivered with the timing set to about 50-55 degrees[X(]. So for those of you who have had the same attitude as mine of "if it aint broke, don't fix it" check you timing!!!
I'll run the engine up tomorrow after i fix the aileron hinges that have given up the ghost again because of the vibes and let everyone know of any improvements.

This is one of the earlier flight when she was still running rich as it was getting broken in..
Thanks
