Appreciate the input Mark and Chris.

Must get a 3 stone honer one day Mark. This is a re-bored cylinder that had been sitting for a good while, just had a little surface rust which has been cleaned up with emery in a (supposed) cross hatch.
Scored a couple of used modules yesterday, in far better looking condition than mine, so one of those with a brass bolt should do the trick.
Oh yeah, do you recall the thickness of the foam in the brackets which clamp the tank? Mine had none.

Chris, do you reckon you got more torque out of your Mustang powerplus mentioned in the above thread?
Did you chamfer the ports on the barrel side, as mark mentioned, on that job? Have read a little on this but not sure of importance. I guess you would at least have to make sure there were no burrs.

Cleaned bolts and painted some little items this morning, also overhauled the decompressor, nothing worthy of photos.
One can see why these mowers held a premium price, I'm almost certain a great majority of the frame bolts, nylocks and the rear axle are stainless.

You must be in a cold part of Qld, our worst so far has only been -2.

Cheers.
