Took the bowl off while carb still on bike, float was moving and looked like the needle was moving up and down w/float?? Put back on, got gas to the bowl, but now there's a leak, maybe the bowl rubber gasket isn't on right?? I'm just gonna take it all off tomorrow so I can see what I'm doing better. Thanks again for the help, will post after problem solved.

if the gas leak is at the bowl mating surface, then the tiny o-ring for the accelerator pump fell out. sits in a slight recess on the bowl, thinks it the bowl side? Been 6yrs since I've taken apart a stock carb. the 42, can do with eye's closed.

Oh Great- I'll never find that, more parts to order??? Thanks Neil
just looked at the manual, that o-ring is toward the front and outside of the bike, the leak was near back and inside (closer to cylinder) sp maybe I'll get luck and that didn't fall out ?? I walked into the basement, so if it's gone it could be anywhere??

A little vaseline helps keep those in place while handling the bowl. Don't over-tighten the bowl screws. Run the screws in evenly. Run all 4 in to the point of light contact. Put a half to 3/4 of a full turn on each screw to even the pressure on the gaskets (O rings) Then tighten to just snug on all four. Finally snug all four screws in a criscross pattern. This keeps the pressure on the seal as even as possible. If you tighen one corner all the way down first, it has a tendicy to push the seal away from that corner, and can cause it to dislodge from the channel it sits in and be pinched. Hope you find that little O-ring bud!

I lost the o-ring after a rejet last year, went to NAPA and got the smallest one they had. It's been in there ever since with no leaks.

When I got my grizzly it had a clear plastic cap over the valve, did you remove that cap?

Disregard my last comment, just went back an saw you are getting gas to the bowl.

Got it. Thanks for the help and suggestions. Still confused as to why I was getting gas to the carb thru the gasline, but I originally only got a couple drips out when I loosened the bowl screw when I originally posted?? I (fourtunatly) did not loose the little o-ring, and it wasn't because I'd tightened the bowl screws incorrectly or different torqued one corner. I did end up leaving the carb on and in the daylight I could see that it wasn't a leak form the gasket area of the bowl, but was overflow coming out by the pilot jet -whatever that other orifice is (manual didn't say). So I knew it had someting to do w/the float, and that's why lastnite I couldn't get it to start, just kept cranking- flooded w/to much gas. So again removed the bowl on the bike still, put a clear hose on the gas inlet held the float up (needle closed) and blew air - no air came out so I know the needle is diong it's job if the float is all the way up??? Thinking I need to adjust the float now I start to remove the screw that holds it on - and I see the metal rod that the screw goes against to keep the float in place is not set correctly -the end opposite of the screw wasn't set in the grove all the way, so everything was just enought out of alignment that the float could not lift the needle up into it's closed possition and gas was running out. Started after several cranks. It's still in the 40's today so going for a ride even tho pavements all wet ( last day of warmer weather here for awhile). I said in my last post "I knew it would be something stupid" seems like I can't get thru a simple project w/out messing something up, turned a 2 hr project into a 2 day affair. Now that I know it starts maybe I can put Erbman's battery cable on tomorrow, what adventure will that bring??? Thanks again for the help

A really good break down of what happened, that will help anybody else, and all the things to look for. Glad you got it going. When you said you opened the bowl drain and nothing wanted to come out, the last thing I thought about was that it could be flooded, and the bowl drain blocked at the time.

Glad you found the problem. I don't know whether you noticed or not but the float retaining screw doesn't have to be removed to remove the float. Just unscrewed enough for the hinge pin to be slipped out from under it. Makes it a little easier to reinstall the float with the carb on the bike, one finger to hold the pin in place and the other hand to turn the screwdriver.
