LT80's suggestion above will tell you if it's fuel starvation as it wont rev with the wheels off the ground...I'd try that 1st...


My neighbor's LT80 was running kinda same as yours...lifted the rear and worked the throttle until it cleared itself...took about 5 minutes but it might do the trick for you...

 

And by "clearing" it self you mean the carb?

 

No, The term "cleaning out" means when there is excessive fuel in the bottom end, the machine will bog/spit/sputter till enough enough air is let in (full throttle) and it clears (high rpm's)the excess out and it can run normally.
I think you need to clean the carb. I didn't see that you did that.

 

Before the fuckup with the vaccumhose I stripped the carb in pieces and boiled it.
But I guess I'll have to remove the throttlestop and let it rip on high rpms for a while

 

LOL! I thought it sounded like hew didn't have his thumb in it.

 

Update:

Cleaned out the carb tonight. Man there was tons of dirt and parts of the disintegrated air filter in there. I cleaned all the jets, put in a new air filter, and put everything back together. Took a few start attempts but got started. Adjusted the idle screw and thought it was good.

I was able to run it flat out with the rear end jacked up and wheels spun fine. I then tried to ride it and it was o.k., but I still noticed the throttle was sluggish. It did not die at idle except once, but again, it would just not have that get up and go.

So, I'm getting that gravity fed petcock like you suggested. I intended to get it anyway like you said just because it's very hard to turn. Fuel lines are clear BTW. This was my first carb clean on anything. Now I've moved onto cleaning the carbs on my gas weed eaters that are sputtering.

 

now it's time to check the compression.

 

Is there a special type of tool for ATV's as opposed to cars?

 

Or the clutches...


Most compression tools come with multiple adapters to handle the different size plug holes/threads...

 

Harbor Freight good enough then to get that?
