Leaky SUs where to buy rebuild

Share this page

Thanks for the Advise and help so far!

I haven't got to rebuild them yet, LarryK (Thanks Larry!)gave me some of the seal kits but I'm still missing the bowl seals and main jets. I started the tear down I see one float has a standard needle and one has a Grosse Jet, should I just replace both with std needles or add one grose-jet? Anyone have good experience with the Grose-Jets?
I think I might just buy a master kit just to have some extras if need be and maybe one grose-jet to see if notices any difference. Also the other kit I have has 2 main needles with 2.0 on them should I use this? Guess it depends on what I have in there now. I'll keep you posted once I get them back together.
 
If one has the Grosse and the newer kits have them use them. Just hope I helped a little.
 
Personally, I'm allergic to Grose Jets. I've fixed more problems by throwing them away than I've seen caused by the stock needle valves. The Viton tipped needles with the spring in the plunger are the best IMO. But others (primarily non TR drivers ??) seem to love them.

Not sure what the 2.0 needles are; those aren't usual SU markings AFAIK. But then I didn't know that TR4s went back to using studs to mount the float bowl, so ??? I've only owned one TR4 and it got pretty promptly cut up for parts (mostly the OD). But I'm pretty sure it had bolts just like all my TR3/A did. The TR4 SPC also only shows bolts, for the H6 carbs.
