"Just purchased this 1986 Star

"Just purchased this 1986 Starcraft FM and decided to give the engine a good checkover. Dealer tells me that not much to a tuneup. He changed oil in the bottom end and adjusted carbs. Plugs he says were OK. I took it back twice after this for rough idling at 1500 RPM. He tells me the 2 cycles are know for this. I have given up on him and am looking for advice. No mention of cleaning carbs, compression test, or possible faulty plugs. Am I throwing my money away to go somewhere else for a better look. It runs fine at 5500 rpm going down the lake."
 
"John, you can get a 2 stroke

"John, you can get a 2 stroke to purr like a kitten at idle (I have 4 of them - motors, not kittens)


Find another service guy - one that knows what he is doing... Could be something as simple as an adjustment or maybe a slightly gummed low speed jet...."
 
It runs fine at higher speeds

It runs fine at higher speeds but still runs rough at slow idle. Decided to live with it.
