how many miles on the motor now?
LIKE, 140,OOO

I GOT TO MY "BOOK" TODAY, IT SAYS:

1)emissions systems not functioning right.
2)ignition timing incorrect
3)carb in need of adjustment or worn.
4)vacuum leak at carb, intake manifold or hoses.
5)valve lash incorrectly set, and or valves sticking.

SO I'LL SEE WHAT I CAN DO.

RESPECT FOR THE INPUT.
