don't try too hard to start it, you could flood the combustion chamber. i dunno if you did all that rebuilding yourself, or if you had someone else do it, but i'd be double checking everything as it's being done.
do a leakdown/compression test, handcranking the shaft.
what's it doing when you try to start it? noises, indications etc.etc. i don't see anything about messing with the starter
