You can not imagine how many times I removed the Webers and the jets and the MSD box and the cables and the alternator and I do not want to go on.
In the end it was that damn rotor in the MSD distributor not being aligned correctly.
Misses at max advance and at cruising speed for several months until I did the cut-up-the-cap thing and found that the phasing was wrong.
The problem is that when they fit the gear at the factory it can be just a matter of a few degrees wrongly pinned to the shaft and the phasing is off. So they should just supply an adjustable rotor if they can't do it precisely.
The same thing applies when you change the gear. Depending the location you are disturbing the phasing in relation to the reluctor.
I had to replace the iron gear for a steel gear because I have a hyd roller cam and that also has made the phasing to be off. So if you start playing with those things an adjustable rotor is probably a must.
