Re: 1989 3 ltr omc dist replacement
The Pertronix electronic conversion won't get rid of your problem as it only replaces the points, you still have the mechanical weights in the distributor.
When you say that you "unstuck" the weights, how did you do this? Were the weights free to swing on their posts, return springs still tight and not rusted to bits. If I'm not mistaken (which I could be, have been before
) the weights should have plastic bushings that ride on the posts,,, maybe not
.
Sounds like you need to pull off the point plate, inspect the weights and springs, disassemble, clean, lube and reassemble. When you are finished you should be able to pull the weighs out and have them return under the spring pressure, all though the will be a bit loose at rest, hardly takes and pressure to get them moving out from their resting position.
As Chieflan said, check your shaft bushings in the housing, the main shaft should not have any play,,, well very little. If it's enough to be felt while rocking the end of the shaft back and forth (where the rotor sits) the bushings in the housing are most likely shot. Been there done that, timing was all over the place and very difficult to get the engine to idle properly.
