62 Scatt resurrected from 30 + years rusting outside somewhere. I went to school for aircraft mechanics and am handy with engines. Actually have some experience with this model which I owned when I was 14. It was new then. Do the math.
I am about 75% done and working on getting the engine to run consistently. Looking thru the exhaust port the cylinder walls and piston head looked very clean and I get good compression. I have replaced all the mag and spark components and had the mag rotor re-magnetized by Stan Waite. It came back from Stan super strong so I know that is not the issue. I did not replace the ignition coil as the spark is now good. Carefully cleaned and rebuilt the carb and triple checked adjustment recommendations. Just took it apart again and all looks good. Replaced the oil seal behind the mag.
The bike will bump start with effort. Will run at high speed with the choke off and 1/2 choke to run at just above a proper idle. No amount of carb adjustment will improve this condition. All the gears run out and everything else is good but the erratic engine speed. Not road worthy.
I really don't know where to go from here.
