Out of desperation this morning, I put in a Gross Jet that I had on the
shelf. The leak is stopped! We'll see if it holds. Now to buy the new
battery (either an Optima or an Exide Select Orbital ) and I might be in
business for Saturday!!!

My two cents: Same here on Gross Jets. The last ones I got last year worked
fine. Going to Gross Jets solved a recurring problem I had.

Sorry Alan-------#2 "Grose jets--throw them away". "Only when you pry them
out of my cold/dead hands!!":):):)
I think we have had this discussion where it was determined that "some" of
the later Grose jets may have been poorly designed. If his are the "older"
(don't know how old) ones, they probably are perfectly OK. Mine eliminated
a frequent problem I had with the original style jets.
