May have a problem. The 361525R1 carburetors were not out to long before IH decided to change them to R92 specs. There was supposed to be enough change over kits sent to dealers to change all tractors sold with R91 carburetors to R92 sizes. Guess all didn't get changed though as once in a while a original R91 showes up. R91 carbs didn't use a high speed adjusting screw originaly, a special plug screwed in where the packing nut goes. Jet was supposed to be sized to work with no adjustment. Carburetor change over kits changed the jet and other mettering parts and added the highspeed adjusting screw. Don't have a original R91 carb to check at this time but I wrote the jet size as .051 for R91. R92 size as .048. Hope this doesn't confuse more than help. found some NOS carburetor change over kits for 400 tractors. Never found any for the 300. Think 300 kits did have a passage plug though, so maybe its changed and not marked.

No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
