I concur again. That's why one of my earlier posts suggested using a degree
wheel and TDC tool to verify the accuracy of your flywheel or front pulley
timing marks. However, accuracy is accuracy. Your justification for
checking the gap/timing of the right cylinder is to be more accurate. If I
was not fully confident that I had set the left side accurately, then, why
would I have a grater level of confidence in my ability to gap/time the right
side? I raced VW fours for years. I never heard of anyone checking the
gap/timing of all four lobes of the distributor cam. I've tuned many V8
engines and certainly never heard of anyone checking gap/timing on ALL 8
lobes of that distributor cam. I just came up with that one and it is
perhaps the best point to make my argument. It IS VERY important to insure
that the mark you use for timing is accurate and that your ability to set
gap/timing is accurate. But after setting the required cylinder, everything
else is either wasted redundancy, or an invitation to induce further errors.
