That sounds very plausible, and might also explain it being a tad intermittent. Definitely something I'll take a look at once she's out of the water, which won't be long now actually, getting a bit nippy, thanks for the idea!
Of course I've been back three times since my last post and it's started perfectly. I will check for sheared key when I get around to it and report back. But for now I'm having too much fun boating! Thanks for all the ideas.
Don't I have to remove the flywheel to check that? Be very happy to hear it if I don't! Boat is in the water about 80 miles from home unfortunately, not so handy to work on.
Just to be clear though, I'm not saying it struggles to start. It only struggles to crank off the battery, and only when the fast idle lever is up.
It will crank with the fast idle lever down, and once it cranks it starts fine (I raise the lever once it starts cranking)
Does that still tally...
Hi folks, my usual starting routine is failing. I lift the (OMC control) fast idle lever high and the battery really struggles to turn the engine over (or crank as some people say). To the extent that there's no chance of it firing. I thought my battery was dying.
By chance, I tried to start it...
Hi, I've recently obtained this motor. It starts ok with some throttle and sometimes some choke but when I reduce the throttle it'll run for about a minute then the revs get lower, lower, lower and it dies. It'll usually start again ok straight after.
I overhauled the carb, needle valve turn...
