Thread: holley carb

Tweet

I have a 750 vac. sec. 3310 carb . I went to change the jet's for the first time and the threads came out with the jet . The carb is about a year and a half old . has this happened to ayone before and what do I do to fix it . If I can't I will have to get a new metering block.I was thinking of a set of Quick Fuel blocks so I could change the jets in the sec. side too .But if I could fix the old one I could take my car out a couple more times before the cold weather rolls in . wich isn't too long away. appreciate any help.

Never heard of this happening before. Contact the customer service people at Mr Gasket (Holley parent company) and they should step up to the plate and take care of you.

i have Heli-coiled the bowl threads before. about 25,000 times ( slight exageration ) but never the Jet threads. there should be some kind of fix out there.

I have a message to holley co. right now but they haven't got back to me . tried looking for a heli coil for this.1/4 20 is all that I could find . Don't even know what tap to get . The threads look like they are 1/4 32 , please help , any info would help right now .

i was just looking around. I dont see any jet repair. Odds are if its some odd sized thread there will not be a heli coil made for it. Even if you managed to get your hands on the correct sized tap, you still have the problem. You could just find another metering block. ? I wonder if the Loc tite form a thread would hold up to the gasoline. Do they still make that stuff?

Tried everything ,gave up oh well I wanted new metering blocks anyway , thanks for the help . Ordered new quick-fuel metering blocks for front and rear through Jegs should be here in a couple of days . Can't wait !!! it's only money anyway right.
