Hi
We have rebuild this engine with
New pistons and rings
New valves, intake and outtake
New rebuilt original carb
New rebuilt original steering box
New cam bearings, size 0.20
Everything was fine but with the old used carb it began to have a knocking sound. And it ran a little warm once and we discovered gas in the Oil. New Oil in and it was good again. The knocking came again. New carb and then we went to get it perfectly timed. Found that one plug on number 8 didn't work. New in and we drove Home. The knocking got worse and we ended up seriously overheating.
Was picked up and back in the garage we disassembled the rod bearings. They are totally destroyed because they have been warm. So we are needing a new crank I believe but I wanna find out why it overheated and why the knocking sound came.
Did we overlook something when restoring it? Or did it slowly begin with the gas in the Oil?
Thanks in advance.
