I have a 43s with a 98cc aluminium engine. It says electronic ignition on the fan housing and it has a delorto carb.
I have removed the head and lapped the valves in. Following reassembly, the head gasket was blowing.
i have ordered a new one, but does anyone know the torque setting for the head bolts? Since they are going into aluminium, i don't want to strip the threads in the block.
