Motor sputter

[Maggie Mae]

Just bought a 1989 Lund alaskan with a 89 Johnson 30 hp , the guy told me when you start it and on idle starts the sputter. First time I started it and turned the throttle and then brought it back down to idle it stalled. After that started it again fired right up and sputter a little bit then stopped then would do it again. I was told it might be the rich to lean controls might need to be adjusted, or carb needs to be cleaned.

You need to give it a good carb cleaning. Sounds like crud or old gas gelled in the low speed jet.

Do you think it might also be the choke or the rich to lean valve ?

Re: Motor sputter

the rich to lean valve is your low speed jet.

Carbs are clean and I adjusted rich to lean and no more sputter .

Glad to hear it. Hope you get to enjoy the rest of the summer trouble free.

Re: Motor sputter

So when I tried changing my gear oil both flat head screws were all messed up on the head. Any suggestions on how to get them off?

Re: Motor sputter

If they are buggered too bad you might have to drill them out. You want to drill a very small hole in them and get an easy out to remove them. They are basically a reverse bit. Sears makes a stripped screw removal too. You might look into that.

Re: Motor sputter

Thanks I will look into that. Also I had to replace the throttle cable and going to order a new one I didn't know if it was possible to have the engine be and electric start . It's a 1989 Johnson 30hp

Re: Motor sputter

Get an impact screw driver and you'll get them out. Forget about the drilling.

Do you know how to measure throttle and shifter cable from console to motor I keep on getting the wrong length . I have a 89 Johnson 30 hp and is there anyway I can start that electrically
