Facts: Original TI distributor. Prev. owner added ignitor system. Do not know why.
Dist in very good shape.
I set base timing at 13º. At 2800-3000 i have around 36º.
Vacuum shows additional 16º.
Basically a sound setting for my engine, perhaps some more initial but it is ok for now.
The problem: after driving the car for a few miles it starts to get tired. A check of the timing shows it to be retarded -10º on base timing!!!! Letting the engine cool down gets the timing back to good original settings... This can be repeated time after time again.
I have checked that the dist. is fixed an not moving. I have put direct 12v to the ignitor module. I have tried with the original coil as well as with the flame thrower coil. I have even tried a new ignitor module. Nothing changes.
I am at the end now and prepared to throw a big pile of dollars on a brand new msd system or something similar....
Any thoughts or suggestions???
Regards, Daniel
