hey...still had the same problems...so i advanced my timing even more...had it idle at 800rpm....i turned it off, went inside for about 30 mins...went to go get something to eat...as i was backing out of my driveway, i pushed in the clutch to put it in first my rpms started jumping again...from 800rpm to below 300 rpms and even died a couple of times...what can i do to fix this..????
