Stromberg 97 Repair?

I should mention that unless you're a real deadeye with the tap, it's a good idea to spotface the gasket surface afterwards. I use a 7/16-24 pilot in a handheld counterbore tool. Works well.

See? That's what I'm talking about. How is a stupid guy like me to know what "deadeye with a tap", "spotface the gasket", and "pilot in a handheld counterbore tool" is supposed to mean? Epoxy still sounds a lot easier to me. I haven't a clue what he's talking about.:confused:
 
FIS,
You are in Vestal...I'm in Orchard Park not that far away.
I make this repair many times a year. As was stated you'll need a small
miracle to retap the thread and have it come out square to the gasket
face. I fixture the bowl in my mill and after retapping the gasket face is
machined square to the threads...it's a quick job.
Email me off site if you wish.

Unlike most other carbs, the 97 carb family inlet to bowl threads do not see fuel pump pressures so a softer gasket is usually used and is more forgiving. I use a drill press with the bowl clamped and the inlet leveled, with both the drill and tap in the chuck to align (my shop is tool poor) . I lock-tight the insert in place at assembly. Has worked good for me on several carbs.

Also, I believe the original type inlet brass fitting could successfully be "JB epoxy" welded into a damaged bowl if prepped well and would not present any leakage problems. The problem would be to change out the brass fitting (and needle/seat) in the future if required.

In addition, the earlier 1934 model 40 Strombergs seem to have less pot metal in the area around the fuel inlet and may fail with any attempts at repair in my experience.

Better be careful cavalierly throwing out the "E" word on this thread. :eek: It can get pretty ugly. (See posts starting with #3 and thereafter.)
 
Uncle Max is the best out there when it comes to Stromberg Service. I wouldn't think twice about just sending it directly to him for piece of mind. Reasonable rates, great service and an all around great guy!

I realize that this thread is kinda old but after reading it, I thought my experience might be useful. Although I don't do a ton of Strombergs, I have rebuilt a few and also sell the new ones. I recently started in on rebuilding a Stromberg only to have the threads come out with the inlet fitting. The problem being, whoever worked on this before me epoxied the fitting in. it worked for him, but pity the next guy who has to work on it(me). I'll use an insert to fix it and save some frustration for the next guy to work on it.
 
I repair them the same way as U Max,only i make them myself out of common brass pipe,threaded inside and outside to accept original fitting threads. ken ct. Fix it right or dont fix it at all.
 
I just found a seriously odd repair and wonder if any of you have seen this...
I just bought a box of Stromberg 81 bases and main bodies from someone and started cleaning them up...
You have all seen Strombergs with the main casting cracked around the area of the inlet hole and that section bent away...common damage on carbs that have been on engines rolled around in a junkyard or in the back of a pickup. Hopeless throwaway castings.
Well...on this 81 as I cleared away the grease and dead spiders, I found that the section mentioned had been apparently WELDED back into place! The metal in the bead matched the carb exactly. They must have used a sliver of a worse Stromberg as their welding rod. The bead was very neat and precise, and I think if it were ground flat would be invisible. Definitely a weld, not solder, not goo, metal melted into the base metal.
Never saw anything like that...I think a very skilled pro job, maybe something done at a commercial rebuilder long ago...?? Maybe WWII period, a time when the V8-60 was actually valuable for mileage with rationed gas and parts were scarce??
