1980 mercury 40 hp. carburetor re-built by a local marine mechanic complete with a tune up ,now it hesitates when coming from idle up to WOT and at that it seems to labor and almost seems as though the timing is off! I would appreciate any and all advice,thank you in advance!!! BTW can anyone please tel me how to set the timing on one of these motors? thanks again.
