I drove it tonight but it was cut short due to rain. I shut it off a few times and it only stumbled once so it maybe getting better. I'm just below half a tank now so I will have fresh gas in it this weekend even if I have to siphon it out. Also the engine only has a little over 2k maybe 2.5k on it since the rebuild and was also converted to HEI. I've never checked timing before. Should I leave it to a pro or could I be walked through it if I buy a light? Thanks,
