i have a leaky bowl on my holly 750 blow through..it always drips around the bolt and plastic washer..so i decided to snug it up cuz it felt loose and it just kept turning!! i took the bolt out and it looks like it was only catching 2 or 3 threads of the bolt..should i heli coil the carb body or get a longer bolt? or what?? thanks!
hey thats a good idea with the wire..ill try that out now, and thanks for the offer on the carb! but ill pass.. i spent alot of money at The Carb Shop to have this carb specifically built for this engine
I ordered my helicoil kit but in the mean time I tried to find a longer bolt.. But holley uses a odd ball size bolt like a 12-24 or somthing like that couldn't find it any where!! It seems I can use abolt about a 1/4" longer then stock to bad I couldn't find it
That's one of the reasons I won't buy Holleys any more. They charge too much for what they deliver with some carbs, and those freakin zinc main bodies commonly strip. I've had the threads come out before the bowl gasket even compressed. They're fine at first, but after a while the threads are prone to fail. Zinc is soft.
Quick Fuel and Pro Systems both have blow through carbs. Pro Systems is going to be the better of the 2, but more pricey. Quick Fuel still makes good carbs though, I run one of theirs on my 67.
