This is a discussion on Help with Float Bowl setting within the Grizzly Talk forums, part of the Grizzly Forums category; Anybody have a process for checking the float bowl setting for an 02 660? They Clymer manual doesn't seem right or my float is way ...
One thing I noticed is that the Clymer manual has you hold the carb in such a way that the bowls are leaning against the fuel shutoff valve. I seen in the other thread, they are holding it right side up and horizontal and taking the .51 inch measurement.
Something seems wrong, it shouldn't be that far off. Is the spring loaded pin on the end of the fuel shutoff needle stuck? That float definitely looks like it's too low in the last pic.
It sure is. As a matter of fact, the new one I installed from my Shindy carb rebuild kit already had it installed. It just clips on the top of the needle shut off, if we're talking the same thing. Like I said, she just doesn't look right, however, it looks simular to the pic in the other thread. Take a peek at his pic and let me know what you think.
In your pic you aren't measuring from the right surface. You need to be measuring from the gasket surface so it's probably closer than it looks in the pic.
On a 660 that a friend of mine owns I raised the needle 1 clip position and adjusted the idle mixture 1/2 turn out and it got rid of the popping on decel and ran much cooler.
I think it's on the gasket surface. I'll keep playing around till I figure the thing out. Btw, I'll have a dynojet kit and it will be on the 4th clip position. Sounds like your friend was having other issues as that sounds like the decel portion of the carb. I think there is a jet just for that and it may be just dirty...sounds like you got it worked out anyways.
