i just rebuilt me 72 oly 399. it starts and only runs with the choke on, it doesnt really rev up that well and when it does it just bogs down. i had it runnin for awhile(10 mins w/ the choke on) and when i took the spark plugs out the left on was cool and the spark plug wire was cool too, but the right one was hot and so was the spark plug wire. any ideas on what the problem could be? when i took the left plug out it had gas on it, when i pulled the right plug out there wasnt any gas.

i found out it running on the right cylinder only. i checked the plugs about 10 times, they r good. i checked the coils and they are both good. so im thinking it is the points. do you think it will idle if it is running on both cylinders instead of one?
