If you don't ask for it to run like a racing machine and and just use the power it needs to
get around , you would be fine . Otherwise these things weigh over 700 lb when fueled .
It's a tank of a workhorse with a low profile track that should spin you out and
leave you stuck if you go out ripping.
I didn't go back and see if you ever drove it or had just picked it up.
The 20x156" track packs wet snow under it and lifts the pogo sticks of the
firm snow and they just bump steer then in the woods. They have the turning circle
of a triaxle truck. Just making sure you are aware how it drives.
Alignment of the clutches and belt width need to match etc.
I has to rebuild my sled (see other posts),( long story) .. Used a SR540 block and
reed valves but still orig carb. It will buzz along at 50mph making its own track
and expect the stock engine did the same.
Good luck
Try gutting you stock pipe if you feel it is bunged ,, nothing to lose. A mig will
sew it back together.
