I have a 6139s 1972 Duster carb that swells up the X rings real quickly causing massive fuel leak into the primaries .

Please , I am desperate after three carb kits to get the correct kit or seals that will not swell up and fail .

Want to not replace this OE carb , when it is first rebuilt it runs really well

Thermoquad is my baby , but flooding is severe

Thank you sooooo much !!

Search Ninja Fuel Systems on Ebay. All the kits they sell are ethanol friendly. That's what makes the seals swell.
 
My one and only Thermo-Quad rebuild went well and the truck ran great. Then a few months later those well seals failed and it ran like crap again. I don’t remember the kit brand, but it was supposed to be a good one. Kinda frustrating

I did these TQ for a living in the 1970s and never had any come backs !!! USA parts ????
 
Living where I do back in the day before internet parts were hard to get so I would use SB chevie valve stem seals and they worked but we never had alcohol in our fuel .
 
Are we talking about "well plug o-rings"? Ninja sent me an email and they are asking me that. Thank you.
I understand they are Called quad X rings????? seal up the primary circuit . When these things leak the old 1972 Chrysler service manual says it will cause a RICH mixture , are you kidding me ???.....never seen a TQ puke more fuel in my life .But I guess they are not O Rings .....Thanks
