[Land-speed] Fuel Injector O-ring Lube...

[John Burk]

Mayf I can tell you how it works with propane . Put new o-ring seals in the 
ball valve of my hot air balloon . One o-ring was too fat and the propane 
washed  the Dow Corning silicone vacuum grease off when I was 1000 ft over a 
woods . Got so tight I hought the brass shaft break . With a solvent the 
benefit is temporary .
