Gave it one more go and fixed it. it was indeed an issue with the fuel inlet valve. thanks to everyone that had helpful suggestions.

Found a local shop that has the Mikuni VM22-133 (what I supposedly got off ebay for $35 USD) listed for $75 USD. ugh... I hate being in a bind

I would put in the listing that it has the flooding issues. Someone may have more patience than me and want to fix it. What sucks is I am supposed to go out riding with my brother tomorrow =/ I need to find a local dealer that will have a carb that fits or clean out my old carb tomorrow...

Well, after tearing it down, cleaning it all out with carb cleaner, checking to see if the floats float... it still just overflows and dumps the fuel... I think I am going to give up and buy one from the local bike shop.

I will test the floats too now since they are out.

yeah I just broke it down and went to town with carby cleaner on it. The cleaner expanded the gasket so I have that sitting in the oven right now to warm up, then I will reassemble and see if its fixed. if not I will consider it a loss, go get a new carb from a local shop and then put this one...

Thanks I will try that now, there is indeed a filter on the line.

So I pulled apart my old carb again and noticed its spring is about half the length of this one... so I used the old spring in the new carb with the same results... ugh

So I have just yanked it off again looking for any kind of grime... its spotless, I am at a loss as to what could be causing this. One thing that caught my eye, is could it possibly be my throttle cable putting too much tension on it making it think the throttle is always partially open? Here...

and its flooding like crazy again... I think I may be a victim of crappy ebay sellers lol.

Well, took it apart, floats were set fine, put it back together and the issue is gone... I must have had some crud messing with the needle before. thanks again for the info!

Cool thanks. Not the answer I wanted to hear though. I was looking forward to opening up a beer, not my carb lol. Time to rip it back off the bike. Thanks again!

Hi All, this is my first post here. I have one of those Chinese pit bikes that are pretty cheap. I picked it up about 3 years ago really cheap from someone that didn't know how to fix it... a spark plug and a few shots of carb cleaner later I had a cheap little 125cc pit bike that ran good...
