Carb problem

[iron man]

So that Grizzly 660 sitting in my driveway is having technical problems. When we rebuilt the carb, my brother put a new gasket on the bowl of the carb from a rebuild kit and it didn't even come close to fitting. So I bought one specifically for the carb and put it on and tested it for a few minutes. It started leaking gas from the bottom of the carb looks like right at or above the bowl about 10 minutes after I fired her up from the same locale that it was before. Thought it could have been the brass screw that controls the fuel flow so i changed that out with the old one and that didn't do a thing. I'm just about out of ideas. I know its not leaking from the tank or any hoses.

Sounds like the pin is missing from under the "Y" shaped bracket that holds the float in place inside the bowl. Not sure exactly what its called though.

I just hope it is correct, easy to miss and easy to fix. :D

I can fix it for a small fee ......$50 an hour 8 hour min ,plus parts @50% mark up.....lol

Seriously it sounds like you didnt install the bowl gasket correctly or the carb is going into a flood stage. The brass screw you speak of should be for the fuel/air mix and one possiblt for the idle. I have never seen a screw to control fuel flow on those type carbs. If the needle or seat is bad it will flood or if you for got the float pin it will.Also make sure the float is in the rite side up . Its hard to correctly give the fix without seeing what is happening .

The hell with that carb, you need to find some more tree minnows!

Thats what the screw is for. We'll pull it apart again tomorrow after we get off the range.

Float pin had the same issue with my generator... Bought rebuild kit and kept leaking from what looked like from the bowl... Bad float pin got stuck letting to much gas in and flooding out

[alex.tallman]

if it isnt the needle valve it may be the float itself and you might have to adjust it. did you remove the float when you had it off the bike?

I have a Yamaha Big Bear that had carb problems and it was easier to buy a new carb rather than rebuild the old one. Bought a new one for like $110 from an online parts house. No adjustment just plug and play.

Shoot man, I can fix it, I'll pick it up, bring to Yama shop, pay for repairs, bring back, charge you 100% markup! LOL
