Re: Noise at Idle

[Don]

quote Drifter:

Well, I took Frank’s advice and spent a good deal of time trying for a clunk. No clunk. So, rather than tear it down, I decided to replace as many moving/rotating parts as possible to see if some “slop” somewhere is causing the ticking. Replaced the armature plate, cam, and flywheel. Clicking still there. Crank keyway looks fine. Removed the starter and roped it, noise still there. Starts easy and idles great, but noisy. At this point, I see no option but to break open the case and have a look. To be honest, I seem to think that it may be something hitting the crankcase. It’s not super noisy, just more noisy than similar motors I own (56 Sea King 5hp). Any thoughts on anywhere else to look?

Instead of pulling it down, perhaps you can just pull off the intake manifold and have a look inside the crankcases, perhaps you will see something marked up…
