Change plugs , next change your gas and check the total advance of the timing as i stated The newer gassers requier higher grade fuel then what is at the pump today and i know some know it all will tell ya ya don't need it . But the gas back when these tractors were made reg. gas was 95 octane and 93 is the minimum . and back then yea ya bought reg. gas . Yes they will run on the low grade BUT you can NOT WORK them . between the cheap pistons and the low octane the added heat that this new gas burns at at peak combustion the pistons will swell a hug amount above the top ring and they can swell enough to seize to the sleeves . Then each time that head was off and trued up the compression ratio went up a little . You may have internal engine damage already , sometimes you can see the scoring by just looking into the spark plug hole . You will never hear predetionation (sp) what you will see is it starting to miss and die and if you pull the choke sometimes they will stay running somewhat and sometimes they die and literally seize up and will not turn over till everything cools down , sometimes they will seem to run sorta ok sometimes they have a light miss that will not go away and sometimes they have a knock mid way up on the block , NOW you have a huge problem . I have a ton of years behind me working on the gassers and spent a ton of money on them . Your dist. maybe a problem as the curve maybe plum wore out . Now on this one ya need to find someone that can run the dist. on a machine and have the curve chart to check it against. I can not see hear or do any of the checks myself so here your on your own .I am just telling you what all COULD be .

When dealing with thinner metals like sheet tin, a long bolt and
