Fookin' outboard engines, one day I'll manage to buy a reliable one...



Stripped it down, carb, all the fuel system - re-assembled and tested but so erratic.

I left it to warm up on 1500 revs or so, then throttled back to 800ish, lumpy but did not stall, revved it up, then when throttle shut it remains at 1500 or so, as you increase throttle it sounds like it's misfiring.

Argggh, fed up with outboards....

What to do next??

Wondering if there's a reed valve stuck or sticking at the back of carb if it has some
I had a Yamaha that was giving same symptoms after stripping the carb down twice & cleaning with no improvement i removed cleaned up the reed valves & one was sticking .

Thanks Mart, TBH not sure what a reed valve is or looks like?? Can you help a bit more?

SamT kindly offered the following too by PM which I'll post up to add to the info:

"Have a look at the coil under the flywheel. AJ was having lots of issues with his, and I had his carb off 2/3 times to clean it, then we thought it was the cdi unit. Turned out the fixed magnets under the flywheel and the coil were rusted. Cleaned these up and the engine ran like a dream..."

Yep it was a nightmare started to cut out through all the throttle ranges occasionally but would start and then got more frequent over time until it finally died. As SamT said we (he!) tried new fuel, cleaned carbs 3 times, new CDI unit, and then he investigated under the fly wheel. Runs like a dream now half a pull on a cold start and it runs perfectly.

It was very frustrating cause their simple engines definitely needed a pro to look at it.

Just had a look under AJ and it's minty mint, like the rest of the engine it really looks totally brand new under the hood.

As you say this is frustrating as hell - never admitted defeat before but I think I might need to take this to a pro...
