After cleaning,adjusting and repairing a couple of spots that looked like they could be a issue...Good spark ! So I put the plug in and poured a little gas in the carb and it runs ! More details and pictures tomorrow.

Good job!  It's always a good feeling to get an SSI unit like that to work, especially since they are so bloomin' expensive.

So I got good spark after taking the flywheel off,cleaning,adjusting,and fixing a couple of things. I put it together enough to test start it. It seemed to run good but the carb need cleaned and it is obvious that I am not the first person to have it apart. So,I took it off and after some soaking and cleaning I put it back together and back on the tractor with the air cleaner so I could try to fine tune the carb. I put gas and Seafoam in the tank and started it. It ran about 30 seconds and lost spark...again ! So being tired of messing with it for the time being,I did the reasonable thing. The 68 Super donated it's carb and ignition switch to my 68 Suburban for the time being. So the 68 Suburban is up and running again and the 68 Super is going to wait on some parts. But that is another post. I will make a post on the 68 Suburban tomorrow or the next day. Sounds like it is going to get cold enough for the next several days to keep me inside a little more.

I think I have that info at home. I will post it later if I do.
First things first, however... What slop on the crank? I would almost bet there is some up/down movement on that.

MH,I checked after you mentioned it and there is absolutely none ! This tractor is suppose to have a new crank,rod,and piston in the HH120.

 

I believe this is what you are looking for,page 47

Thank you drbish,that was exactly what I needed.

 

They don't mention they have any way to adjust gap. Only timing.
Any slop you can muster, move it away from the magnets and turn the assembly ccw to the stop.attachicon.gifimage.jpgattachicon.gifimage.jpg

Thanks MH.
