Rebuilding M4MC Carb

[Tomeal]

I want to rebuild my carb. Never done one before and I want to learn. Question is does anyone know of a good video to follow along to. Found a couple I like, but some of the shots are out of frame. I've read slot, but I'm a visual learner and would like something to go with.

Also any tips or tricks to watch out for being my first.

Already have the rebuild kit so I'm going to dive Right in.

Well that came apart pretty smooth.

Choke setting looks off?

Gotta get some cleaner and pick this up later in the week.

pretty decent video.

if you take out the aptscrew, be damn sure you count how many turns it takes to pull it out, and put it back in the same amount.

Edit, as I was typing your 2nd post popped up.
Was gonna say take lots of pics.

quadrajetparts.com has full rebuild kits floats ethanolresistant accel pumps, throttle shaft bushing kits, etc.

At minimum you should buy a kit, new accel pump, float, and the power piston retaining collar, and a filter.

that choke setting could be overdone to compensate for a non working spring. rich setting keeps it engaged longer, lean is less time it stays on.

take some 800+ grit sand paper roll it up and polish/clean the power piston and accel pump bores. clean up the metering rods and make sure they or their hangers aren't bent.

the throttle shaft screws for the butterflies are staked on the back, use a dremel or file to grind them smooth if you want to take them out to do throttle shaft bushings. mark them L and R to make sure they go back where they went. use some kind of loctite on those screws as well as the choke flap and secondary flap screws.

Ahh, someone praticing on their own so I could drop off my spare one later...

Let's wait to see how it does when it goes back on!

always buy my rebuild stuff from them. got a bunch of parts.
type the carb number in and it gives you every part they sell that fits that carb, and others.

Is there any plastic hiding elsewhere in the choke assembly that I shouldn't soak it to clean it?

After rebuild should I set the mixture screws to where they were when taken apart or is there a recommended starting point?

For reference this carb/engine sat for 10 years before I got it. Would never idle for crap. Had to fight it to start, then give it a little throttle til warmed up, then it would settle down and idle on its own.

That's why I figured a rebuild wouldn't hurt, just need a base to start from.
