I hate to say it, but it sounds like you got the valve timing off by a tooth.
I have run into this before with other cars that use timing belts or chains.
Somewhere along the installation of the new chain and gear something slipped a
little. With a belt driven engine it was pretty easy to loosen the belt and
kick the gear over one tooth, I know it's not that easy on a Spit engine.
Good luck!

Subject: HELP WITH TIMING!
OK, I took some time and examined my timing problem a little closer. With
the engine warm, off fast idle and idling about 600-800, and the vacuum
tube connected (per the manual), this is what I found. At 10 deg BTDC (the
prescribed timing) the engine would run albeit not that great and around
500 rpm, adjusting the timing all the way back past the timing marks about
a half inch (probably around 30-35 deg BTDC) made the engine run a lot
better. Took the car for a test drive (about a mile) and it ran pretty
well, however, the exhaust doesn't smell quite right - smells very rich I
think. Any opinions on this one!!! Help please.
Thanks
