[Mg-t] Gas leak Jet Bearing

[brown dan]

Gentlemen,
 
Another email and the Moss Carb video pointed to the jet and that screw.  I
undid the jet lever and screwed the jet back tight.  I reattached the lever
and started it up.  NO Leak.
I know that I need to do a total carb overhaul, maybe after summer.
Thanks for the help and info.
 
Best Wishes,  Dan

Using 'O' rings is a two edged sword.  The size needed is a 010.  Definitely
DO NOT use a plain nitrile 'O' ring as it will swell in a very short period of
time when in the presence of fuel and make it impossible to pull the choke
out.  Viton is a better material  as it will not swell as quickly or as much
when exposed to fuel, but it will ultimately swell to the point were the choke
cannot be pulled out.  The absolutely best 'O' rings to use are teflon, but it
requires two in each position to work correctly.  Teflon 'O' rings are
available from Tom Bryant.  Tom can be contacted at: tbryant at suscom-maine.net
or 207-443-6338.

Before attacking the seals, check the screw that holds the linkage fork to the
bottom of the jet.  The screw often loosen up and leaks around the fork,
making it appear that the seals leak.  Removing the screw, cleaning the
threads and reinstalling it with some locktite will cure any leaks at this
point.

Cheers,
Dave
