Thanks Max and Tyler,
Lots of good info there, if I get time today I will pull the motor off and see what we have here.
Tyler, interesting and I would love to know how they fitted a heavier crank in there but I know I have a fix for them by adding 500 grams to the crank nut.. Not sure if I mentioned it with the 24 I built last week, but once I had fitted the F/C to the base and went to fit the decomp hose and took the cowl off and no decomp just a broken spark plug. I had been using this motor on my test mower with the Flintstone wheels and it was an easy starter with no issues starting.I thought low comp and I would have to put rings in it but I was against time as the bloke wanted it for a couple of jobs on the Saturday. Thought I would see if it would start but as you can guess the big kickback, just as bad as any the PT's could give. Put a decomp valve in it and perfect. The property the bloke wanted the 24 for, the owner had died at least 3 years ago and by the look of it probably hadn't been cut for a couple of years before she died. When I first saw the pics of the property I told the bloke he needed a 24, he had no idea what I was talking about but could I get him one in a hurry when I said to him it would get the place all chopped down in half/three quarters of an hour he couldn't believe it. All I could show him was a base and a box of bits a mower I would take the motor off he was staggered. I dropped the 24 off to him at the job on the Sat morning, showed him how to use it and before I had left he had the whole back yard slashed down in 20 minutes as he tapped on his watch. A very happy camper he is, couldn't wipe the smile off his face.
