    Bottom cyl has spark but will not burn. Any clue where to start on this? Had it running on top cyl today but had to leave it partially choked to run.

    We've got one of them in the shop now to be worked on.

    Start with your fuel system. Check for leaking lines, clean out the tank, try to get some kind of filter in the line between the tank and carb, and because your choking it to run it, I'd suspect a carb cleaning is needed.

    Forgot, do a compression check before you do anything else.
