retro 4,048 Posted February 24, 2020 It looks like there is something holding that float valve open. Its probably a spec of dirt or a small flake of rust. I would open the drain screw on the float bowl and allow the bowl to drain completely, then open the petcock and let fuel flush the float valve for a bit. Then tighten the float drain screw and try again. Share this post Link to post Share on other sites

I think the fuel line may have been bad and I couldn't see it, judging by what's in the bowl. Edited February 24, 2020 by F250 guy Share this post Link to post Share on other sites
retro 4,048 Posted February 24, 2020 Great, you can fix it before you go back to the farm to reinstall. Once you get the leak fixed you can test that float valve by slipping a small funnel onto a short length of fuel hose to use to fill the float bowl. 1 Share this post Link to post Share on other sites
shadetree 5,884 Posted February 24, 2020 here's a simple trick: before you install the float bowl back on the carb ?, ( this works very well if you have a bench vise ? ) place the carb in the bench vise, attach a fuel line to the carb, use a squirt can, or funnel like retro said ^^, add fuel to carb, all while your holding the float up all the way, when the fuel line is full ?, slowly lower the float, then back up, see if fuel leaks past the float needle ?. think of this as eyes on test ?. 1 Share this post Link to post Share on other sites

Thought about it but wasn't sure how it would work with the bowl off, I'll do it and report back. 😁 Share this post Link to post Share on other sites

I do it all the time this way !. saves me from having to put the bowl on, take it off, back on..back off..when I can watch all this while the bowl is not on the carb. just don't do it in a enclosed area ?, or your run the risk of making yer wife mad from fumes ?, or blowing yourself up ?!..lol. 1 Share this post Link to post Share on other sites

Never done it before lol but hey I'm up for learning. I hate hot that fuel tank is made on the 300s almost impossible to get my hand in there, can't find a small copper tube or vaccum pump electric of course. So shook it yesterday sucked with a house junk vaccum shook upside down some more while sucking. Can hear you be grain of dirt still but the screen will stop that. I don't think I'll have my buddy clean it I'll see what this does to fix. Share this post Link to post Share on other sites

F250 guy 107 Posted February 24, 2020 (edited) Didn't have a hose long enough to suck fuel out of my riding mower so I used water and an old 4 inch long section of fuel line, long story short, couldn't see well enough cause the water would drop off the pin when closed so I pulled the hose off and blew by mouth and I didn't hear any hissing when float was up so I'll get a fuel line and run er this weekend.
