SOURCE: 1974 60hp johnson outboard won't run on full throttle.

Carbs probably need to be cleaned and re-built. Common problem in outboards that havent been run in a while

SOURCE: We have very little reverse any thing above idle

There are two things to look for. With the motor off disconnect the shift cable. Pull the boots off the plugs so the engine can't kick back. Grab the shift lever directly on the motor and pull it in the direction reverse is. Turn the prop and you should be able to feel reverse click in. If you just barely feel it "tick" the gears, the shift rod inside the housing is not adjusted. If the reverse "bites" into place as good as forward then leave it is that position. Next, line up the shift cable but DO NOT connect the end with the shift lever. Put the cable in reverse and you will see a gap from the old setting to the where it has to be to work correctly. Then its as simply as adjusting the shift cable to match the lever.
The second possibility is the rubber hub in the prop. It could be slipping. But usually its gone in both directions when this part breaks.

Hold the carb in your hand in the position it is in on the motor the float and the carb body should be in line with each other. What year and what type of motor,these directions hold true for 90 percent of outboards. Jim OMCRetired Mech

Fuel mix is a common cause of this kind of performance. Take special care to follow the manufactures instructions on fuel mix, most modern outboards run on100 to 1 while it is easy to continue an older mix like 50 or 33 to 1. Sometimes the mix is written on the engine cowl.

Cheers, Timo

How do you advance idle rpm?


Hello R Lynn Johnson,

This question is submitted under Cars & Trucks?

Timing and Idle screw... I don't think so...?

Actually sounds like you have been adjusting the CHOKE...

I hope you are COUNTING TURNS... Because what you are describing about "timing" certainly does NOT sound like you are working on any car I've ever seen.

It would be wise to set everything back where you started...

DISCLOSE WHAT MAKE, MDDEL & YEARS...
(engine & transmission)... you are fiddling with and PERHAPS WE COULD STAND A CHANCE OF TELLING you WHICH SCREW is your idle speed screw (if any).

Else I would strongly recommend you buy the books for your car and study up...

Is there an air fuel mixture adjustment screw? I'd try lookin for one and adjust it a little and see what happens. Sounds like your mixture is way too rich. A more lean mixture won't bog down, but too lean of a mixture will bring your idle speed up too high
