Grandpa's old cub is living again

[Mach5rider]

Grandpa's old Cub Loboy is finally coming together and looking like a tractor. My daughter and I took it for the maiden voyage - first time under it's own power since it was disassembled at least 30 years ago.
The short story is: freed stuck valves, new head gasket, carb, sediment bowl, clutch, wiring harness, electronic ignition, alternator, rebuilt starter, brakes, seat, rebuilt hydraulic touch control, rebuilt danco 5' deck, rebuilt Servis 5' deck. and many other things I'm forgetting.
I'm currently assemling the sheet metal and getting a fuel line from the sediment bowl to the carb. However my sediment bowl seems to be leaking around the gasket - slowly weeping from the top of the bowl. I wonder if it has to do with the screen interfering with the gasket seal. Any ideas on what I may have done wrong? I have a new sediment bowl but it seems to have different threads and doesn't fit my fuel line. So a new fuel line or adapter could be a possibility, but it's always good to see the original IH parts still doing their job after all these years. I'm trying to get this going as we're well into spring here in Ohio and it would sure be fun to get some seat time on it.
Thanks to all who contribute to this site as it has been invaluable to me on this project.
If I can figure out picture posting I'd put one in.

Hi,
Good that you have the Cub running again.

Often the gas strainer bowl gasket won't seal if it is old, and you try to reuse it. They need a new gasket. TM Tractor at the bottom of the page has them.
There is supposed to be a screen above the gasket, all of them I've seen are smaller than the OD of the gasket, so it doesn't interfere with the gasket sealing.
Sometimes the nut needs to be tightened slightly with pliers, if it won't stop dripping.

If the Cub has Touch Control, and the hood is on, move the Touch Control arms to the rear or down position before working on the gas strainer, it is easier to get to the strainer.

Good advice from Glen.

If the brass screen is the same diameter as your gasket, chances are it won't seal. Use a pair of sharp scissors (not your wife's ) and trim off approximately 1/8" all around the screen. Reinstall and check. Additional trimming may be required. Just don't trim it too much; shouldn't be smaller diameter than inside diameter of gasket.

Glad to read you have your LoBoy up and running. Take some pics and post; we'd like to see.

The metal seat can warp/deform over time from over tightening the bail. Test the seat for flatness by firmly holding the glass bowl in place without the gasket or screen and see if it will rock back and forth.
I have also seen one where the hooks on the bail, or the shape of the bail, was slightly off and the thumb nut bottomed out on the threads before it pulled tight enough to seal.

I realize this is an old thread now, but i feel i should close the loop: i had a new large screen and it was as described by Stanton above. Once i switched to the old screen, with a new seal, it has been sealing ever since. In fact for an old machine, I'm impressed overall with the lack of fluids on the garage floor. There is a weep of grease at the rear of the final drives and thats all ive noticed.

Congrats on the fix.

Sometimes ya just gotta tip your hat to those engineers, parts builders and assemblers ect. behind these Cubs. They did well!

Glad to hear you got it fixed up!

BTW: It's perfectly alright for the original poster of a thread to come back after some time away and update everyone. So, thanks for doing that.

Thanks to all for providing this useful platform and generously sharing information to enable us new folks to learn and have the tools to keep these tractors going for another generation.
