[Mg-t] Gas leak Jet Bearing

[Dave and Liz DuBois]

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
