"I just put new pistons and rings in my 1980 DT65. It seems to idle a little rough, but runs. It will Idle like that till it runs out of gas. BUT as soon as I throttle it up and try to come back to idle it surges, bucks, spits and dies.
After it dies on decel it is hard to restart. It also runs real rough and sputters at around 1500 rpm. If I give more throttle and get the rpm up past 2000 it runs great.
The plugs are dark but I blame that on the 25:1 break in mix. Could it simply be loading up from the 25:1 oil mix?
I have 2 sets of idle jets 85 & 67.5 the problem exists with either set of jets."
