I did the timing the way they told me to - do one cylinder first, the rotate the crankshaft 180 deg. a certain way, and do the other, but maybe I screwed it up somehow.

The valves are the old ones, I have the old cylinder too.

I will try as you suggested, and take it apart again to redo the timing and check the valves - hopefully I will find the problem.

Thanks alot for your help, bdtsr!
