Issue with chain rubbing torque converter

[bob58o]

Did you mention if you tried playing with the choke. If it is too rich, you might not need the choke. Some times there is a real choke (limits air) and sometimes it’s a fuel enrichment circuit (adds more fuel).

Anyway see if it gets closer to starting (or worse) by flipping the choke lever. Might have to play with throttle and choke. I’m not really sure what is going’s on.

Well thoughts appreciated lol so that all advice you got for me on why it’s not cranking?

Well you've got gas in your oil so I'm going to have to go with you're too wet to make fire

As for why, I can't be sure. I've never had a carb be that much trouble... not even the PZ19 I stuck on a Briggs Flatty despite being way to rich... it ran decent enough and belched fireballs from the pipe. I only bailed on doing anything with it on account of not being able to find the parts it needs to actually use.

It's a VM22 clone so it's got an enrichment circuit like a PWK except with a choke lever instead of a pull knob.

I'm thinking he's most likely got a compound problem on his hands where it's multiple little things making one big shıtshow

Do yourself a favor and start with default settings on the carb after you check it over like you said you were going to.

If it comes off, take it off. Enrichment plunger and ALL

Needle Clip in #3 (the very top/leanest is #1)
Screw in the A/F to soft seat, back it out precisely 2 turns
Screw the idle in to soft seat, back it out precisely 3 turns

Double check the intake lash with the exhaust at max lift (.005- .007)

Double check the exhaust lash with the intake at max lift (.007- .009)

Double Check the sparkplug gap (set to 028)

Double Check the ignition airgap (set to 0.4)

I have tryed both and nothing I do makes the crank sound any different “very low pitched hits, only 4 or 5 strokes I guess I would say” an oh **** got some big stuff coming now lol I don’t know which one I’m lacking but I only have one screw adjustment on this carb that I know of. I took it off an looked the extension piece did appear to be of the seal a little I centered it up perfect an no change.. but how do I measure for all these specs your telling me

 

[Ryanhodge2715]

I tryed all settings on the needle an none sounded different won’t even try to turn

 

[Ryanhodge2715]

lol I know engine good we was just ripping it the other week,

You do realize that "choke" lever down means the Enrichment circuit is open... right?

The enrichment being open is the equivalent of having the choke on and it sure as hell would explain why you're flooding it to death and can't get it too start.
[Edit]

My bad, I looked closer, that doesn't have the double pivot down is closed... you are a textbook example of why I avoid Mikuni and Chikuni (Chinese knockoff Mikuni lol)

It is however being held open by the nut on your intake manifold so there's your problem right there. Pull them bolt and flip them so the nuts are against the intake with washers, the choke lever SHOULD clear the bolt heads, ideally you'd toss those in a junk bin for something else and use a pair of button head allens (much lower head hight because of the domed shape "button") to hold that carb on.

As for the measurements, you need a feeler gauge

 

[Ryanhodge2715]

so your thinking it’s just a bad carb?

No RE read

I had to edit because I noticed something VERY critical and easy to miss

 

[Rat]

That ain't right dude

With the enrichment "choke" fully closed, that clicker on the lever is FULLY seated behind the hump on that spring blade.

Try flipping the screws, if it still hits without fully closing replace that junk pair of allens with button head allens... they are them domed ones you can only drill out if they strip because there's not enough to get ahold of with pliers or vice grips

 

[Rat]

You fix that and it should run, but I wouldn't do more than get it started and let it burn off all that excess fuel and blow out whatever is hanging out in the exhaust still until AFTER you change the oil.
Gassy oil doesn't lubricate worth a crap... kinda like how watered down liquor just doesn't inebriate worth a damn lmao

 

[Ryanhodge2715]

Nothing is touching or hanging up?

 

[Ryanhodge2715]

I take it the choke is off when then plunger is Down an when I lift up is on correct?

 

[Ryanhodge2715]

This sucks man I’m sure it something I’m probably doing wrong not gonna have it fixed for the party today I’m wondering if the jets that come are to big maybe they need different size?

 

[Thepartsguy]

Is there a fuel pump in use?
You can't use a pump with a slide carb, they exclusively use gravity (there are VC carbs with a built in pulse pump)

Smittys garage YouTube channel put a slide vm22 knockoff from eBay on his briggs 8hp and ran it off a pulse pump. He plumbed the pulse line to the valve cover.. His 8hp big hoss minibike Mikuni swap video.

 

[bob58o]

Is there a good seal here?
At least in this photo, something seems off.
I know you mentioned something about centering something better.

 

[Thepartsguy]

It’s not a choke... it’s a fuel inrichment port. As in you pull the lever lifting the needle out of the port. That opens the port and vaccume (pushes)?? Raw fuel through the port. And closing the enricher allows the needle to drop into the port blocking it so no raw fuel flows through the port.

 

[Thepartsguy]

If you are starting with the enrichment on it will chug a bit dump raw gas into the port and the engine pulse/chug of trying to run will spit all that raw fuel directly out of the carburetor opening.

It will sort of backfire puff raw wet fuel right out of the carburetor. My kohlers run great but I can leave the enrichment on so it dumps raw fuel and floods real good to get it to spit back out through the carburetor.

Dude it's not that kind of can't, don't confuse the ametures that already have a hard enough time getting their shıt to run and stay running.
