Re: spitting
Has the carb been removed? Could air be getting into the flange?

Re: spitting
However the timing is correct, I could give the inlet more clearance, see of this will give a change.
I don't think there is a leak at the manifold but I can put a special tape over the joints see of this is af any influence, thanks for the info guys.

I noticed a small hasitation in closing of the inlet valve while turning the crankshaft slowly, valve springs? The springs were within specs so I didn't renew them.

My M18S had a slightly bent valve stem. It was 0.010" out of true but was sticking in the guide.

Re: spitting
I didn't check the valve stem, because all was new rebuild including grinding, but I'll check the rockers and valve
