Run non-ethanol gas in it. Use premium oil and change often. I stuck a valve in my snow blower but thankfully it is a flat head. Varnish being the culprit. A lot of gas stations now offer non ethanol fuel for boats and tractors etc. You can look up gas stations in your area on the internet. It is more expensive than the absolute garbage they pass off as fuel today. When I was a kid you could go to Hess and get 101+ and Sunoco had 280 premium which was I think 104 octane with lots of that beautiful tetra ethyl lead in it. I miss the good stuff. I know my Mustang with 10.5 to one compression idles better and has more power on race gas but at over 10 bucks a gallon it is crazy.
Jon, run avgas in your pony, 100LL actually has more lead in it than the old leaded gas.
