New to the site - but looks like a bunch of great information!! Need a little help - my father brought over his Grizzly 660 today and looks like it needs some carb work, I have everything removed from the carb except the throttle cable - can someone please tell me how to release the cable from the carb. I have taken the 3 screws and the cover off but do not see how to release the cable other than unscrewing the allen screw?? Any help would be greatly appreciated! Thanks

 

Anybody?

 

Open the throttle all the way. Than take a pair of needle nose and grab that brass fitting that the cable connects to and rotate it counter clockwise with lite pressure pulling upwards. You will hit a slotted section the cable passes through and will will pop right out

 

The thing you're looking for is the little circle brass piece on the rotating throttle assembly. Its spring loaded fairly tight. Much harder to get back on than it is off. I normally rotate it around with my fingers, then wedge a flat screwdriver in there to hold it up (allowing slack in the cable) while I pull out the little brass cable stop. Slide the brass piece off the cable after that, and then the cable will come out of the hole and you're good to go.

 

It worked - thanks for the help!!! Got it rebuilt and it cranks and idles great but give her gas and the popping and skipping begins!! Any Help??

 

I had a similar problem. My buddy has a 2007 660 Grizzly and his wouldn't start. Took the carb out and found the needle was stuck. Cleaned out everything and put it back together. Started fine and idle was good. But give it gas and it sputtered or died, but once it reached passed half throttle or so it ran like a champ.

Come to find out while trying to get teh needle out I bent the float tab and the bowl wasn't getting enough fuel. Here is the carb lesson I learned with this carb.

(Sorry I don't have the carb with me so this is mostly memory)

1. There are three jets to this carb (as do most probably have).
A. The first jet you need to check is the Starter Jet (Choke). That will cause your choke not to work, which doesnt seem to be your case, but for anyone else this might help. This jet is the short and round brass one (maybe 1/4 inch long).
B. The next jet is the pilot. That is the long narrow one. This guy controls your 1/8 to 1/4 throttle. So if you can get your machine to start, but it dies or runs really rough till you get past that point, it's either a plugged jet or not enough fuel in the bowl.
C. The main jet is the largest one. This guy controls 1/4 to 7/8 throttle. Fuel level really won't effect this one (I don't think anyway) unless you dont have any in the bowl. But if it's plugged than you are going to have poor preformance or will die out when you gas it after 1/4 throttle.

2. Fuel level was a pain. Not hard to set, but I had no idea the height needed for it. So I found a 02-06 manual. Float height is suppose to be 13mm, not pushing down the needle, carb upside down and level. Blah! Didn't work for me, I ended up pulling the carb back out, hooked a hose up to the carb, blew in it, and slowly closed the float myself. When I finally had it closing about an 1/8 inch past the pilot jet I put it all back together and it ran perfect.

Hope this helps, if not, hope it helps someone.
