This took out some of the effort required to move the shifter, but MAY be contributing to what you're experiencing.

I'm not saying that IS your issue, but I'd start by looking there.

Good to know! I've read about the washer trick, but my mind didn't go there on this problem. I was immediately thinking that the reverse lockout solenoid was either broken or there was a bad electrical connection somewhere. I'll definitely take a look since other mods have been done to this old girl over the years...

Thanks...

It should be a minimal charge. The rockers have to come off to replace the springs

Shouldn't have wasted my time since my dial indicators only have a range of about .250/in.

Keep in mind my time included removing the arms, rotating the engine, removing the trunnions, replacing with new parts, cleaning/reinstalling the valve covers, coil brackets, spark plugs, wires, yada yada yada... I'm sure experienced wrenches can do this stuff much faster than a hobby wrench like me...

I admit those che trunnions look damn nice, nicer than the straubs... I like how the bushing also has an oil channel machined into it, there should be no issues at all with oil supply... at the time I did my straubs I don't think che were selling self install kits and your rockers had to be sent in
