_Wilson_™ 6,558 Posted March 8, 2021 sounds like the float valve, or dirt maybe keeping the valve from sealing good to the valve seat, might also check the drain screw, if it's ever been loosened. 5 Share this post Link to post Share on other sites
Goober 1,555 Posted March 8, 2021 Yeah not supposed to drip like that. Yes a loose drain screw could be an easy fix. Leaky float valve could eventually drain your tank, or if it gets worse, could leave you without fuel on the trail. Sounds like those 17-20 year old carbs are due for a rebuild. 4 Share this post Link to post Share on other sites
Tim-ANC 202 Posted March 8, 2021 But it's only been 20 years! 😄 Rebuild, good advice. Will put on my to do list. I've seen mentioned around here that a Shindy brand kit is the way to go. 1 1 Share this post Link to post Share on other sites
jeepwm69 7,582 Posted March 8, 2021 Yep, Shindy is the way to go. Some of these are an easy fix with a rebuild. Some of them require some extensive polishing of the brass seat to get the leak to stop. Sometimes I haven't been able to stop it and have had to get a different carb. But definitely check your drain screw first, make sure it's snug. Then pull the carb, thoroughly clean it and put a Shindy kit in it. Check the condidition of your fuel line and replace if it's old rubber, and clean your tank out thoroughly. 3 Share this post Link to post Share on other sites
_Wilson_™ 6,558 Posted March 8, 2021 just be sure to keep the petcock off, when till this issue is fixed, could also leed to a hydraulic locked cylinder, or gas thinned motor oil, i had this happen to a lawn mower engine, (thinned motor oil) while i was mowing, the shut off valve stopped the flow, when not in use, but running, the gas flooded the crank case, but i caught the issue, and I installed a new seat, and float valve. 2 Share this post Link to post Share on other sites

Tim-ANC 202 Posted March 8, 2021 How much did the kit cost and from where? I've got other problems requiring my wrench time. Will try to get my wife to do it. She has a knack for rebuilding carbs. 3 1 Share this post Link to post Share on other sites

Thanks😊 If you are having problems with a overflowing carb , make sure the fuel tank and petcock are clean , if you rebuild /clean out the carb and don't check the fuel supply , you might fowl it out right off the bat again , one flake of rust from the tank or some crystalized fuel with cause the flow neddle valve to not seat and over flow ---- don't think no one mentioned , if the float sticks , it can overflow into the cylinder and leak past the rings and dilute the oil , etc ,etc , got to go hold that thought 3 Share this post Link to post Share on other sites
_Wilson_™ 6,558 Posted March 8, 2021 (edited) well, she did a great job on the camo covers. @Tim-ANC I'd say go for it. Edited March 8, 2021 by _Wilson_™ 2 Share this post Link to post Share on other sites

Goober 1,555 Posted March 8, 2021 when i service a quad, first thing i do is remove and clean the fuel tank. Plastic tanks are easy. I spray the fuel gauge and petcock bolts with Deep Creep, then i remove them—EASY does it—low torque!! and then i wash out the tank with warm soapy water and a bottle brush. Dry with hair dryer. Lookit the bottom on the tank. Rough surface for trapping grit. 3 Share this post Link to post Share on other sites
SittyDown 37 Posted March 9, 2021 (edited) @Tim-ANC I ordered a kit from eBay because the seller shipped from Indiana.

Thanks😊 Anything to polish the seat the float needle sits to help it seal is worth a try. I've done many things like a Q tip and valve lapping compound on the bad ones to just tooth paste on "clean" ones. It's always good to be in the habit of shutting the fuel off if the machine is going to sit any length of time though. It only takes one drop of moisture to break that seal and allow fuel to slowly flow and possibly cause an issue. 2 Share this post Link to post Share on other sites
Goober 1,555 Posted March 9, 2021 I haven’t had any problem seats, so i just clean them gently with a cotton swab. I use clean Berryman Chemtool on my carbs. No dips or boiling. Most importantly you don’t want to get any scratches on the seat! my favorite is to use a plastic Blue Bunny ice cream tub. The carb will sit up in the tub without sitting in dirty fluid and I can still get the lid on. 4 Share this post Link to post Share on other sites
slowindown 494 Posted March 9, 2021 When I restored my 06 foreman last year, I was having persistent problems with the carb leaking some fuel. I cleaned the carb probably 3 times. The last time, I wrapped super fine steel wool over the cotton around the ends of q-tips. I made two or three of these. I pushed them into the seat and spun them with my fingers a time or two at fairly light pressure. I havent had it leak since. 5 Share this post Link to post Share on other sites

jeepwm69 7,582 Posted March 9, 2021 That JB welded carb that I posted a pic of a while back and thought was a 350 carb was actually a 250SX carb. Think it would be the same? If so, you want it? 1 Share this post Link to post Share on other sites
Goober 1,555 Posted March 10, 2021 QA02A? I am trying to pull the float seat out of that aftermarket carb. Has not gone well. I don’t have a bush extractor. How else could i do it? Machinist? Share this post Link to post Share on other sites
THH 295 Posted March 10, 2021 Does that aftermarket carb have the screw next to like shown in this picture? Did you remove the screw? If not it may be pressed in and difficult to remove if not impossible. I have run a tap into difficult ones to get a better grab for removal, 8mm or 5/16 UNC taper tap. 1 Share this post Link to post Share on other sites

I figured you might want to practice on a junker. 1 Share this post Link to post Share on other sites
