Chronic carb leak fix-when all else fails

Like the old saying says: ''When all else fails,stop using all else.'' Look for something different.

I've been fighting a carb leak for months now. I have replaced needles,polished needles, cussed screamed and almost sacrificed a chicken to the cause. Gas would randomly pour out of the overflow nipple no matter what I did.

Well,while fooling with it tonight it finally dawned on me that the fuel level in the bowl was not high enough to reach the top of the overflow tube I was looking in the wrong place.

Problem was I had a cracked overflow tube. Blowing on a hose on one end,finger over the other and a dip in a bucket of water exposed the leak.JB weld fixed it.



Kinda hard to spot,but here's the crack.it's at about 3 o'clock.

LOL   Hey,I'm a busy guy.If I'm not working my job, I'm working on a project.

I did find yet another cause of my leaky bowl issue. I was bummed when I fixed the cracked tube and still had an intermittent drip. Turns out,I somehow obtain every faulty part ever manufactured. The float in the suspect carb was soldered together wrong. You can see where one of the float thingies is pointing out rather than in. It was getting hung up and would just barely seal.Go figure...
