So i did this and this is what i got:
inlet: 145
exhaust: 181
transfers 84
do those figures mean anything to you?
thanks

hmmm, that doesn't sounds healthy... Problem is i don't understand those figures, is there any way to learn more about what standard figures should look like and how to adjust?
Since i think this engine won't be running as it is, I took the barrel off and started to strip it down. It will be undergoing a full rebuild this winter. (new seals, clutch, bearings... everything replaced by uprated materials to cope with a bigger engine)
