I am going to re-test it and the float tomorrow to make sure.

Ill bet that fence would get better performance if it was fuel injected.  ::)

I am going to re-test it and the float tomorrow to make sure.

The 'ting' test  ::) (a small tap on ea. brass tank while holding the float by the center hinge part) to each little brass float 'tank' w/ a coffee stir stick is very 'telling' for me.  ;)
The ring that it has will resonate differently between ea. side if it has fuel inside of either one;but you can't be 'tone deaf' otherwise it won't work.  :D

Figured out the carb leak today.  Looks like I might be in the hunt for a replacement bowl unless I can figure out a way to repair it.  I filled the bowl up with gas and let it sit for a while.  When I checked it there was a tiny amount of fuel on the overflow tub that comes out of the bottom of the bowl.  Wanting to see exactly where it was leaking from I plugged the hole in the pipe that is inside the bowl with my finger and blew some compressed air into the overflow tub.  I instantly saw the bubbles.  Nothing like 42 years worth of galvanic corrosion to make a pin hole.

Thought it was a stand pipe problem, Seal All may work.  I'll check to see if I have a spare float bowl in my 350 pile of stuff...Larry

Looked up the tech specs on the Seal All.  It says that gasoline breaks it down.  Seeing how it will be submerged in it I don't think it will work.  Another suggestion has been to braze it.  I like that idea, but I don't think my mini torch will get hot enough.

there was a thread where someone found a brass tube at a hobby shop that perfectly fit over the stand pipe.  Forum member Jim French could fix it for you if necessary. I haven't had a chance to go out and check my reserve supply...Larry

Can't you just put a bit of solder on it?  Shouldn't need much at all....

Bring it to a craftsman/artist who understands how to heat different metals and let him use his smallest torch tip to braze that area;it'll work Harsh  ;)

Better yet, send it off to be micro welded. Costs more, but last indefinitely. And holds permanently.

Cal,He has it so very well prepped already braze will readily adhere to both those surfaces.

I think I am going to send it off to one of the members here that does micro welding.  I think JimF is his user name.  I need to send him an email and see if it is something he can do.  The different metals might be the only issue.

I tried heating it with my micro torch and it didn't even remotely get hot enough.

+1  Have Jim F micro weld it. 

I can just imagine the look on a jewelers face when you go in and ask "Can you please braze my carburator float bowl?"..... Ha!

Picked up a new carb pretty cheap so the leak should be fixed.  Waiting on a few parts to arrive because the wife changed her mind on what she liked...go figure.

Other than that I haven't had much time to work on the bike because I had to go to the great white north.  I can officially say that my relief is in the house.  My daughter graduated bootcamp last Friday and is down in Florida for her initial school.  She is going to be a jet engine mechanic.

Progress is slow these days since I don't have a lot to do and I am saving for the paint job.  However, yesterday I replaced the float bowl and mounted the new tail light.  I like this one much better.  It retains the stock shape, but isn't nearly as ginormous.  Unfortunately, I dropped it and cracked the plastic.  It wasn't bad and I could have super glued the crack and no one would have ever noticed.  The bad part is that the tiny brass piece that the screw that secures the lens goes into snapped off the backing plate.  So a new lens is on order.  I am glad you can buy the individual pieces.

I also mounted the tank just to get it off my work bench.  It actually looks like a bike.  Now I just need the new seat cover to arrive so I can get it mounted.

Looks really good, Harsh.  If you don't mind, where are you getting your seat cover from?

I bought the seat cover from dis-covers on eBay.  They sell a matching strap with it as well.  This is the one I bought.
