Thanks for the info. I did locate the part on partstree and it was very expensive $291.00 plus tax and shipping total $325. The part wasn't much bigger than a quarter. I'll try and include a Pic. Anyway I installed it and the UTV runs well. Yes it is gas not propane. I switched to non-ethonal gas.

I've discovered the part number in question schematic callout (210-253) is actually 280-62358-08.

I have a 2014 landmaster S/S 4x4 model 653 4x4 with a 22 hp robins engine. I've been having problems with the govenor reving after it running a short distance. I cleaned the carb and discovered the fuel membrane has a slight pin hole (P/N 210-253). Can not seem to locate a replacement. Any suggestions? It appears this carburetor is no longer supported.
