I've just been going through the Fine Tune Manuals for '79-'81 JD Sleds and comparing it to the '82.
Why did the Liquifire go to richer Power Jets from '82 and why richer on the PTO side? If I put in a HSR ignition into my '80, would it also benefit from going to '82 spec jetting? Would it benefit anyway?
Just trying to absorb as much info as I can on my new (for me) sled.

Re: Jetting 81 to 82
All 80-84 Liquifires should be jetted the same. Deere updated the jetting of the 80's (several times) under a few different update programs. Be careful some of the early service manuals don't call out the updated jetting. See this post for the last jetting

The post doesn't mention the inlet needles were size 1.2

Re: Jetting 81 to 82
Hello! I have a 1980 JD Spitfire with the Kawasaki engine and Mikuni B34 butterfly carburetor. Is there anywhere to get parts for this carb? I am missing the piece called the "pilot bypass". I was very confused as to why the sled won't idle. When I went step-by-step with the manual and disassembled the carb, I discovered that I am missing this piece! Please help! Thanks. Eric (PS, I see that this thread is 81-82 but it was the closest topic I could find! Sorry!)
