Update- purchased yet another dist cap!!!!
AND the wear around the graphite contact is normal!!!!!.
Appears the new caps are machined in that way for some reason?.
My original one was not machined in this way!.
BUT the damage to the detent in the cap allowed it to move/rotate a small amount- enough to change the ingnition?.
Anyhow, test run proved no problems so far!.
Gave her some 'welly' and she performed fine!
The only thing I can NOW sumise, is that I either did not fir the new rotor or cap properley resulting in degradation of both!.
The Original cap contacter was worn giving me weak sparks which maybe were weakened more by a weak system and rain!.
When I finally looked at the dist cap and rotor I guess I fitted either or both badly!.
So..... $1000 for a new rotor! not bad
But at least she runs!.
Now to try and get the idling sorted- minor problem!!!!
