I have a 1992 Johnson motor that will not idle properly. It runs great otherwise. I have changed the spark plugs and the fuel line filter. This did not correct the problem. Could it be the timing. If so, how do you check and set the timing. Any help will be appreciated as I am 50 miles from the nearest boat repair.

Here are the suggestions I got when experiencing the same problem with my '99 Johnson 175.
In addition to what you've already done.
Make sure the gas is good.
Everyone I talked to stressed the importance that the carbs not be set too lean, which can cause a catastrophic failure of the motor.
There is probably someone here to help with the timing question. I'd also suggest getting a service manual for the motor if you don't already have one.

My first suggestion is that you get a Repair Manual.
It has been said that, "He who works on his outboard without a manual has a fool for a mechanic".
What you should do then depends on what '92 Johnson engine you have, but most of them should have a careful link 'n' synch (carb linkage adjustment and synchronization) procedure.

Check the fuel hoses and OMC fuel connectors ("o" rings) if you have them. Air leaks were the root of my problems.

It would certainly help to know if this 1992 engine is a 2 hp or 250 hp.
I'd run some engine tuner through it before tearing into anything.

DO NOT MESS WITH THE TIMING! Timing rarely if EVER goes out on 2 strokes. It probably needs a good carb cleaning or a synch & link(mechanic needed for that). I would try Techron in the fuel first.
