I did go to small engine warehouse.
I spent more than thirty minutes there,especially in the natural gas fuel section.
I did bookmark it.

I am still interested in “transplants” from water pumps, mini bikes, etc.

My father abused me terribly as a child,
buying me mini bikes, six wheel ATVs, motorcycles.
all of whom broke down,
and I was lured into “addict labor” repairing them with my two brothers.
Addict labor is worse than slave labor,
a slave can work at the lowest effort to avoid the whip,
but addict labor will work with a near frenzy to get back to dangerous thrills.

This “devious dad” even bought us a used 40 hp Wankel engine to transplant in place of a Wisconsin 12 hp.

It got far worse - he bought his sons airplanes after they all soled at age 15.

He drew a line only at helicopters - which he repeated called “10,000 parts all trying their best to kill you.”
