to be honest I has thought it was a exhaust relief but couldn't work out why as its an elect start however nothing to say this power head wasn't originally a manual start.
trying to up the compression, do you think it will influence my final result? got to get it up from 110psi.
off to the machinist tommoz to have 0.6mm taken off the head (maybe more if he thinks he can do the squish, weird shaped combustion chamber not domed like normal so he may not be able to). I want to bring compression ratio up to 8.0:1 - 10:1, these come stock as 6.5:1
