Just got it firing!
Hi,
I built my bike out of a garage full of parts belonging to a Friend. The pieces have come together pretty well, it's almost done. I timed the engine before it went into the frame, but when it came time to fire it up, no joy. Now I'm going through the timing process as described on This Old Tractor, with the engine installed in the frame. I've been through the process five times, slowly and carefully, but always when I install the #2 exhaust valve rocker and turn the crankshaft, the exhaust valve hits the piston. The numbers on the degree wheel aren't lying, so I'm wondering if I've somehow got the wrong cam or pushrods installed in my engine. My feeling at this point is that the next step is to pull the cam and check it out with a caliper. Anyone out there ever encounter a problem like this?
