1986 Mighty Max, New to me

High idle may be a result of the dreaded 'Mikuni Fiddler'. Reset the throttle stop, then check the ignition tune. if you have power through the rev range then you know the secondary is working (no power from midrange rpm up is a dead give away the secondary vacuum solenoid has failed). If you have a flat spot on opening the throttle, check the accelerator enrichment pump (small square housing with a vertical linkage on it - either a blocked jet or the pump diaphragm has failed) The Mikuni is a horrid carb to work on, but as you live in Kalifornyastan you are stuck with it to meet emissions testing.

It has power across the entire range, really fun to drive actually.
I'll search on how to reset the throttle stop although I have decided to go with a webber carb. Dealing with all these vacuum lines and recirculation lines is just not worth it. I learned that on my 85' landcruiser, spending months sourcing used parts from the east coast and down south.
I dont live in that place you mentioned, I live in California and know ways around those things you speak of. Haha
I wish I could find a decent looking header. Anyone have any experience running a header? Looks like the last fella that was building them stopped years ago. Sure would tie the room(engine bay) together after the webber goes on.
This is the carb Im looking at.
