Ive got an 1990 135 Merc that bogs down coming out of the hole. Runs like a champ when it plains off but it just struggles to get going. If i run it for awhile, stop, and then start up again it acts like it doesnt want to run. Once it does turn over it will sometimes die when you put it in gear. Ive had it to a local shop but they see an old man walk in the door and they cant wait to rob me blind. Said they adjusted to the factory settings, but it still does the same things.Im not afraid to make some adjustments, Just want to be sure I dont screw up anything. <br /> Thanks for the help. Dave
