That was my first problem to deal with after bring home # 21205
cant have the garage filling with fumes for too long.
There was leakage thru the valve and draining into the carbs.
I disassembled the body and took the black rubber or neoprene gasket and
turned it upside down.
IN my case that solved the problem. It seems the rubber sagged or was
not tight against the hole in the valve.
Turning it over gave a new seat area. Luckily its symmetrical.
good luck Pete

Hi All,

Well...I must say...I am about sick and tired of always dealing with leaky
petcocks.

The originals on my 70 Ambo are seeping a bit and I was wondering what
others have done to combat this cantankerous issue. By the way....does
standard plumbing thread tape hold up against gasoline?

On my 69 Ambo I have installed the newer type (from Convert etc...)
petcocks with an adapter available from Moto International. Works
perfectly
except the petcock comes down too far on the left side and gets in the way
of the throttle cable coming out from the top of the carb. Right side is
ok
though.

I was thinking of running an adapter 90degrees and bringing the petcock
further back. The pitch on these threads are 12x 1.0 right?

Any thoughts would be appreciated.

Regards....Ian
