Greg, Jane, et. al,
I'm considering just that, leaning out the carbs, for my TR3A if it doesn't
pass the NJ DMV Inspection I need to get done before the end of October. It
was really lean last year and it passed, but it runs much better-richer.
I'll try it the way it is now, but if it doesn't pass, I'll be leaning them out.
The thought of a quart of essentially "ZERO Weight" Marvel Mystery Oil in
the crankcase still seems like a possibility to me. I've used MMO as a
cleaner, for 500-1,000 miles at a clip, but never as part of my normal
lubrication. It's just really thin, and I've always considered it to be
mostly a detergent/penetrating oil, great for disolving and cleaning out the
accumulated GUNK in the oil system.
JMHO,
Jack
