Oddjob:
Does it make the sound if you kickstart it?

I don't think you can overshim it Roo, I used to squeeze as many on as I could and then remove the thinnest and fit the circlip and I never had any problems.

As for the gearbox bearings, did you change them?

Good news on the cam journal surfaces though.

Are you 100% sure it's coming from the bottom end?

Have you got a spare starter? Just in case it's that.

I did have a starter motor oval the bronze bearing that sits inside the end covers, AFAIK though those bearings are self lubricating, however a little oil in them couldn't hurt. Have you worked on the starter motor at all, I think it may be possible to overtighten the screws holding it together and that could cause the shaft to squeak inside the end of the bearings I suppose.

I could also be that the starter motor has dried out over the years and what you are hearing is rust and dirt being removed. It may just go away on it's own.

If the motor starts and runs ok and when shut off emits no undue noises I'd not be that worried if I'm honest.

Sesman:
Not wishing to be a pessimist, but did you ensure that the cam blade tensioner was correctly seated in the crank case pocket?

Sesman:
On the topic of starter motors. Mine ran fine on the bench, but couldn’t resist stripping it anyway to clean out the carbon and install new brushes and holders.  To be fair it was pretty pointless as the bushes were only about 1/5th worn. I did note a little play in the shaft though at the bushed end. Excessive wear might create a backlash engagement issue on the over run when load comes off. Just wondering. 🤔

Laverdaroo:
I completely refurbed the starter, bushes, cable, paint the lot. I bench tested it several times, just in case of a fluke, you know

All spot on and refitted. I’ve not dropped the oil yet as been sorting the dawg’s tea out

After your starter mention, sounds like a worthwhile mission, I’ll whip the starter out and have a look at that as that’s the path of least resistance to start, leave the oil until I need to.

Every bearing in the cases was replaced with NEW. So I have no worries with that and all worked lovely on the bench and post assembly. I even had Uncle Bryan cast an eye over the selection etc and was given the nod and a thumbs up so not worried about that end of the motor. I could understand the clutch squealing a bit but never experienced it before.

Do you mean the two long screw/bolts that go from top to bottom as on here? This was when it went in…..

Run it until something breaks? Then you'll know what was making the funny noise!
