I'm having problems with my engine stumbling. It gets worse the longer I drive it. I replaced the plugs and have noticed better performance but did not resolve the problem. I'll check the carb and intake bolts this evening to rule out a possible vacuum leak, I have done this before and i don't think that is the problem either.

I'm hoping you will tell me its possibly due to the timing. I have a buddy coming over next week to check that as well as the vacuum.

Can't wait till the end of August when I'll pull the engine out and start fresh.
