petcock

[mainiac]

I was removing my carbs for cleaning and when I pulled my fuel line off the brass nipple pulled right out of the petcock. I am going to have a hard time trusting it not to leak or come off again. Is there some kind of epoxy or something that I could use to put it back on? Maybe a little JB weld or something?100_0472.jpg Also I get terrible mileage, no better than 35mpg, no matter how I ride it. I have stock exhaust and air box with a KN filter. However I saw that the PO had replaced the main jets with 102.5's and all the information I can find says they should be 100's. He also drilled some 3/8 holes in the bottom air box. I have ordered some 100's from jets are us and plan on sealing the holes on the air box. Am I being reasonable to expect better mileage than 35 mpg? Any thoughts or suggestions would be appreciated, thanks

I might trust JB Weld temporarily but I think it's time for a new petcock.

Yea, you are probably right. I have another one that works, I just never head of one pulling out.

I've had it happen before. I just gently tapped it back in with a small hammer. i believe the hole is tapered slightly. No leaks, but ya' never know. Mine has been working great for a year!

By the time you tap it back in gently, it will be seated nicely and sealed, so a touch of JB Weld around the outside of the joint should hold it securely and should never get wet with gas.

I put a little JB up near the shoulder of the nipple and tapped it in with a block of wood. let it sit overnight. Looks good this morning. Thanks

i think it might be a press-fit anyway, no big deal
