1984 Honda xl200r. Installed new cylinder, piston and rings. New fuel lines and carb. New ignition coil/spark plug wire. Valves adjusted correctly and installation sequence followed by clymer manual for third time now. Wont start, it was trying to advanced and kicking back. Now only backfres once in a while. I've noticed on the compression stroke at TDC (when the spark should spark) the pulse rotor is 180 degrees away from the pulse generator. This is why I have been back into the top to see if I messed up the sequence of installation but it all checks out as far as I can see (if that is a problem maybe thats normal the marks between rotor and generator not lining up at time of spark...im not sure and manual says thats correct since you cant put the rotor on wrong with the locating dowel and all) I need help....
