so...
finished the new head , with new valves , new chain with new guide as well, got oil n coolant n fuel ,
came to start it up after all this work and waiting, and checked compresion,it is 39 psi, tho engine not worm (daa) , and for some reason starter motor seems pretty weak(with plug in , and with plug out) , like its not sound like strong starter.
valve clearence is good , and tested with big battery at 12.8 v
got spurk, and check the timing 100 times its 100% correct,

bad starter? or something due the compression?
should i try kick start it?

Possibly. The contacts get corroded inside if it has been used in muddy or wet conditions. Try to pull-start it and see if it fires up.

I’ve never heard of that brand. Yes, there should be washers on the head. No idea what piston brand or compression ratio it is. Welcome to amazon!
