Float needle jets leaking!

[John_Progess]

I took the car (64 BJ8) out for a ride and noticed that it was leaking gas and determined it was the front carb. I cleaned the needle and seat and it seemed OK. Took it out for a second ride and the rear carb started leaking gas! What is the opinion of the group about gross jets vs. standard jets. I hear a lot of pros and cons about both. Do you think I should replace the needle and seats? Thanks and have a good day!

Some folks prefer the Viton tipped needles, some prefer the Grose Jet valves. Simple as that.

I switched to Grose Jets about 10 years ago. They seem to work fine.

John,
I experienced fuel leaking from the float bowl overflows a few times, probably from gas tank rust. When I finally installed a new tank, I also switched to the grosse jets. they seem to work fine, but the others probably would have as well when the rust problem was corrected.

Obviously it could be dirt in the fuel, but we've fitted gross valves after two sets of Viton ones from Burlen refused to seal a d they've worked immediately, so I think the Gross are better.

We do lots of SUs www.richardjamesupholstery.com

So perhaps have more opportunities for failure.

I had the same problem with already new (standard) valves and was not very confident to solve the problem when I ordered the grose valves - but had no better idea.

What can I say now: from the day I put them in the problem with the overrunning curburetters is gone.

I had Grose ones and they leaked. I now have the viton-tipped standard ones and they have been fine. I also cleaned out and coated the tank interior and have a fuel filter.

I too am a Grose-Jet Valve man.

is the jet leaking or the needle and seat? I just ordered new jets from Joe Curto because my jets are leaking.Great service but for some reason they sent three of them.
