fixes for loose venturis?

[Rick Kirchner]

After many hours my 32/36 has a venturi that's rattling about. Are there any recognized fixes for this tat really work? I'm going to buy a new one anyway but I'd love to be able to use this one as a spare.

I can't help with this too much, but check out this guy on ebay https://www.ebay.com/sch/i.html?_ssn....m3561.l161211

I've bought lots from him and it's always been great and at good prices. He's in Bologna too.

A couple of Center punches on the non sealing side of the body has worked for me.

I did that several times over the years with a Weber 32/36.

I've done the same thing, but use a small flat face punch. Moves more material and less noticeable

doesn't the carb still suck air around the venturi instead of through it?

I would think so.

Nobody on the planet knows Webers like he does. He has done 48 IDAs and 40 and 45 DCOEs for me. Excellent service, good Gent.

A couple of walks with a flat punch and hammer of your choice to the side of the carb works pretty well.

Most of the air flows around the venturi in any case. All you're trying to do is seal the contact surface where the fuel gets sucked in so it doesn't pull air instead of fuel.

Some have used vert thin shim stock

Some have used very thin shim stock

That'll work unless it gets loose and sucked into the engine.

I always shim them I dont like using a punch on the carb body.

[Rick Kirchner]

Id think that a shim coupled with some thin high-temp sealant would be the way to go. Hadn't thought about shimming.

[DaveW]

Don't use sealant on the inlet end - it might block the fuel passage.

Rick:

Another thought.

My new rear hubs are slip fit into the rear new upright bearings. That is to say, the hub flange effortlessly slips into the bearing race. As explained to me, the anodizing of the hubs were decorative in nature as opposed to MIL-SPEC. The difference in the two processes is a couple thou in diameter. Thus, the MIL-SPEC anodized is press in.

I contacted Loctite, and spoke with their racing tech, to understand there is a bearing adhesive to 0.020” to secure bearing ID/OD areas.

I have the two item part numbers (one, the sealant, one, the cleaner). Biggest issue: 400 Fahrenheit to break the bond. This will most definitely eliminate the air bypass issue, and a THIN coat might release easier.

I've always used a little bit of an aluminium coke can as a shim, works perfectly.

Rick, the best solution I have found is to take the Venturi out and gently squeeze it in a vice (use soft jaws or a rag) perpendicular to the tube axis to deform and create a tight fit to the body at the port. Does a better job of sealing to the port and lasts longer than the peening of body. I’ll be at Buttonwillow this weekend if you want to talk about it. Todd

Thanks Todd! Unfortunately I won't be there. Hope you guys have a good event.
