Be careful what you buy.... I purchased a carburetor that was tagged from a Polk auction with writing in black marker Oliver 88 & he had it listed as a Marvel Schebler..... He didn't bother to look at the tag on the carburetor which is marked 13750 which is a Zenith & way bigger fitting John Deere 4000,4010,4020..... He wouldn't answer email & because I purchased in the winter January he wouldn't respond... So I turned to PayPal they on the other hand would but somehow I sent them his tracking information instead of mine tracking number.... Now I have misplaced my tracking # mailing it back to him / seller. So now I'm out my purchase price $142 and $11. to ship it back to him
