Another option, is to put a piece of neoprene hose over the nozzle of the
torch. This gives more control over where the gas is actually flowing. I also
used to use an acetylene torch with a small tip, "0" or "1" and correspondingly
low regulator pressure. (@ 1 psi)
To give an idea of what the change could be, put a small amount of fuel gas
into each carburetor venturi and note the rpm and 'smoothness' difference.
Using the hose, and the small amount of fuel gas (at low pressure), move the
hose around each of the base insulators or even the manifold gaskets. Check
around the throttle shafts. Don't rush and BE CAREFUL, you are using a fuel
here!

One of the Haynes repair manuals I have suggests using a unlit
propane torch for finding leaks. They tell you to crack the valve open
where you think there is a leak. Can someone try this first ? Maybe
Alan can he will try anything :-)
