    Remove and clean Nikki carburetor on 21R7070039

    You may not get anything like that from me. I thought about writing an illustrated instruction sheet on the procedure. I worked 14 years for AGCO doing technical writing on everything from windrowers to combines to big square balers and the electronic control systems. That's why I asked for...

    Remove and clean Nikki carburetor on 21R7070039

    I very much liked the final part . . . so the spring that will end up spearing your finger no matter what you do . . .:LOL: A fellow is not a mechanic unless he gets at least one skinned knuckle or bloodied finger. I will plan to take photos and see if I can do a good writeup.
