Re: [DML] ODD vs EVEN Fire

[Jim Strickland <ihaveanaccount@xxxx>]

Hmm,

I didn't know this; I guess it is because of how the manual shows the
firing order, 1-6-3-5-2-4. I noticed from the distributor cap that there
were three sets of 2, and had just assumed that it was 1-6, 3-5, 2-4. I
guess a better firing order might have been 6-3-5-2-4-1. Besides having
the '1' as the starting cylinder, is there any reason for the firing
order as published and not as I have written, assuming that My Wilson is
correct?
