Howdy from Calgary, Alberta Canada. I own a 1964 John Deere 3020 tractor and am looking for information on the Zenith carburetors as my tractor's spark plugs need to be changed after every time I use it, which is never more than an hour at a time. This problem as existed for several years and seems to be getting progressively worse. Any suggestions?? Thanks and I look forward to all the information I can get. :thumbsup:
