engines that have run on natural gas have much less internal wear and tear and/or corrosion issues, as the fuel is much cleaner than gas or diesel.  It is not uncommon for an engine ran on natural gas or propane to run double the time it would on gasoline.

If it's still hooked to NG then you most likely won't have carburetor or fuel pump issues.

And you might find NG is cheaper to run than gasoline.

Hurry up we need to see a video of that thing running & sawing..

Only downside to running an engine on natural gas or propane is increased exhaust valve and seat erosion, and slightly less power. Stellite seats solves that problem..Lots of pluses. Lube oil practically lasts forever,
