Seems to run OK at various speeds but will not idle in gear. Stalls out after 3 or 4 seconds at lowest speed.

How about some history?
Compression and spark ok? Idle speed set correctly?
What's your model number, will tell what engine you have.

Re: Johnson 48 Idle problem

Actually I have two 48s mounted on the same boat, both seem to have the same stall at idle speed problems. All plugs are new Aug this year and gapped by the book. Models are J48ESLGER and G48ESLETE. I think that makes them a 94 and a 93. I have no idea how to set the idle. I have not checked thje compression. New gas cans, lines, and premix (50:1). As to history, the boat and motors sat unused for several years. Any help is appreciated.
