All old Shindaiwas and Redmaxs. I mostly ran 230 Shindaiwas. Still got some new ones. Bought up all I could. Very glad I did. Rebuilding all the old ones while parts are still available. When I feel parts will dry up, I will spend as much as I need to to stock up for a couple decades worth of parts.
had a T25 and wasn't able to locate a new carburetor,they seemed to lay down every few years on me to the extent of no being rebuildable and EPA restriction laws on the manufacture engines . So I bought a Robin instead and now they're forbidden from being sold in the US EPA
