Yes, a previous owner did a pretty bad job of the conversion, too... I
have a giant box sitting over my engine, 'cause the carb sits so high.
Single carb, 2 barrels, centermount. Other than that, I haven't a clue
what it is...
I have never actually jetted a carb before... doesn't that involve
disassembling it?
I usually run about 15-16 MPG in city, with 20-22 on highway... though
if you believe my gauge readings, I made it from Lynchburg VA to
Greenville SC on less than a tank of gas not too long ago...

This is another thing I'm going to try and remedy before next year's
invasion... put the Stock System back in her, try and get a bit better
performance that way. I'll go out this afternoon and take a look at the
seals and such... what would I be looking for?

And I'm fairly certain that my rear hatch seal is bad... just like all
the rest of the door seals... yet another expense, I suppose. Oh well, I
love her anyway. :)
