If the engine is revving and the quad is not moving the clutch is fried or needs adjusting.. I thought from your description the engine was bogging down..

 

thats just the thing, doesn't rev , just acts just like brake is on. goes up same hill just fine when just starting

 

Try turning the choke partially on when it happens and see if it gets better or worse..

 

Another possibility is a bad coil.. Less spark when it gets hot..

 

why choke it then. how do i test the coil?

 

Putting the choke on 1/2 way will add fuel.. if the condition improves you have a lean condition.. If it gets worse you have a rich condition(which I doubt). If it does nothing it eliminates the carb as the problem..

I usually replace them but there are ohms resistance tests for a coil..

 

Great i'll try the choke . Thanks a million .

 

Does this have a chinese spark plug in it? If it does replace it with a NGK C7HSA and see if that helps..

 

not sure about the plug ill check it. a few things , carb float over flow filter doesnt drain , filter looking thing has no outlet, and seems to be way too much draining from float. bogs down with full throttle, so i cleaned carb, took apart and all. no change with carb cleaning. is better with 1/2 choke. whats the remedy for this?

 

the spark plug just has an R on it
