Since I have a set of Accel coils installed by the PO on my SR, I was poking around the Mr. Gasket site for information. Reading through the instruction sheet, I came across this little gem:
11. As ACCEL's coils are quite powerful and deliver a much stronger spark than original equipment coils, considerable care should be taken after their installation to be sure the carburetor jets on your model are adequate. A "hotter" spark normally requires larger jet sizes in order to maximize power output and prevent a possible lean fuel condition that could result in an overheated or possibly damaged engine.
Followed by this:
ACCEL cannot be responsible for consequential engine damage caused by the installation of these coils if the consumer does not address the possible resultant lean fuel condition the installation of these coils may cause.
Now, I lay no claim to being an expert on things related to engines, but this is the first I've heard of this. Just how can the spark change the mixture? The fuel mixture will burn at a given temperature depending on the ratio of fuel to air, not what ignites it. Am I off base or is ACCEL's legal department just covering their @$$?
For the record, the last time I checked the plugs in the SR (last year?), they looked normal.
