I just received a pair of Dellorto 45 Trijets that I had planned to clean, rebuild and mount on my 2.2L JH engine when I'm finished. When I opened the box and removed the carbs I found several deep scratches and a couple of deep gouges to the surface of one carb where the carb mounts to the intake manifold. No question in my mind that the damage will interfere with the "O" ring sealing. Any suggestions as to how I can salvage the carb? Is there some kind of filler that can be used that will fill in the damage and smooth the surface out so it is like new again?

You can try one of the aluminum-filled epoxies. Once the stuff sets completely, you can smooth it down with the aid of oiled wet-or-dry sandpaper on a glass plate, and/or one of those $10 electric die grinders the auto parts stores sell, depending on the exact nature of the damage and the repair. And if that doesn't work, and if time and labor costs aren't issues, there's aluminum brazing, and even welding.

Mark, thanks for the response. Any brands you recommend or stores that carry something I could use. I have a can of Metal to Metal from Evercoat that is used in body work, but I don't think I can use it for this application due to the exposure to fuel. I have heard of products like what you are referring to but have never used one. If someone on the board knows where I might find something please speak up. I think the damage is minor from closer inspection. The largest gouge is along the outer edge and does not seem to be of any concern. There are several deep scratches though, that are directly under the "O" ring. These definitely need to be filled and sanded. Good suggestion Mark. I will do some research to see what I can find. Someone on the Jensen email list mentioned some products that might work. Now if I can just find the email.

I don't have any specific recommendations, as I haven't had to look at one of those epoxies for quite a while. Thanks for mentioning the fuel resistance, it had slipped my mind. If the damage is only a little more than what you could expect the o-ring to seal, you might try applying Hylomar over the entire sealing region. I've done that with my Strombergs and have had zero leak problems for the past year-plus. The stuff remains flexible indefinitely.

Dan, I have had good luck with Devcon products for repairs of this nature in the past. Their products supposedly match the physical properties (ie. thermal expansion, etc.) of the parent material. You will likely have to go to an industrial supply store to find it or order from somewhere like McMaster Carr. Andy
