I have an 02 Grizzly 660 that is not wanting to rev. It idles fine but only revs to, and I'm guessing, 1500-1700. If I hold my fingers over the intake and carefully regulate the amount of air going into the carb it will rev like normal. Could this be caused by a short? It is getting enough fuel to the carb and I just had the carb rebuilt by the dealership so it "should" be clean.

Thanks

 

Im sorry for going off topic but how much was the rebuild....


if u coverup the carb and then it runs fine i think your geting to much air (odviously)[img]i/expressions/face-icon-small-tongue.gif[/img]:

 

they might not have the vacume diaphram seated correctly,or got a hole in it while they were working on it

just fishing????? take it back to those who rebuilt it

 

its probably clean, but the jets arent right they need to readjust them

 

I just realized that I did not mention something...it ran fine in both high and low gear for about five minutes but in reverse it would spit and sputter. In reverse would at least move on level ground not it won't do nothing besides stall out. In addition I had it idleing in the garage for about five minutes with an occational quick rev just to check before I took it out for a ride.

 

It almost sounds like the reverse limiter is kicking in. Is the motor breaking up like there is water in the fuel?

 

Since I've forunately never had water in the fuel in any vehicle I could not tell you for sure. That being said, I guess it could be. How would I check for the limiter?

 

I agree kinda... You are not able to achieve the desired 13/1 air/fuel ratio. It is possible that you may not be getting enough fuel.

 

Actually, I was wrong. If putting your hand over the intake made it run okay, then it is a fuel problem. Does running with the choke on make it run better. The choke is just a fuel enricher. If it does run better with the choke on, then it is definetly a fuel problem. Also, check your spark plug and see what color it is. Mabye, change it to eliminate as a possible problem.

 

oops my bad posted to the wrong thread
