I've been looking at all the worn out H-4 front levers in my collection. The cost of new levers are big bite in ones budget to replace. I had thought of recasting them but figure that would be too much work and cost Then I thought drilling and reaming out the oblong holes and inserting brass bushing in them. After going on line and finding that each bushing I would need cost 69 cents each plus $9.95 shipping I decided to make my own.

The bushing came out decent but when installed the hole they didn't come out centered. (I know why) My thoughts were to try them out on my 58 to see how much off of adjustment the SUs would be.

At this point it makes me wonder if anyone else who rebuilds SUs have tried this and what they came up with. Maybe the answer will save me a little time and work.

This may not solve your issue.
The only 'ovality' I have encountered that I thought would/might need correcting has been on the enrichment lever link thingy end. (below) I have always left this alone.
I recognize that one carburetor will enrich more than the other with this 'ovality' but have never worried about cold weather starts.

If I thought this a big enough concern, my approach to correcting this would be to;
1- carefully size and ream the hole in the brass lever
2- machine/turn short length of solid round bar to an interference fit to this reamed hole in the lever
3- press this into the arm and drill the appropriate size hole for the clevis, the lever or what ever.

Make sense?

You way is about the best.....But I just bought a watchman's lathe and am playing around with it. That's when I spotted the front levers and figured what the heck! I do like the idea of a bush in the lever. It's cheaper if it works.

John, I have put bushings in mine when I rebuilt the carbs. Mine were not as bad as yours but I did drill them out then pressed the bushings in.. soldered them in, then drilled them out to the correct size.

John,
Moss has those levers for $13.00 each (370-680 and 370-690). They are reproductions but don't appear to be too bad. I'm installing them on a set of H4s tomorrow. I'll let you know how it goes. At $26.00 for the pair, it's hard to justify doing the required machining to repair the old ones. After working a little over 25 years as a machinist, this is a no brainer (again, if the Moss parts are any good). On the other hand, if you are just looking for a little machine shop challenge this would be a good project.

Wayne,

I'm cheap, Haven't you figured that out yet? I feel that the price these levers are selling for are a little too high. Every little part adds to the rebuilding of the SUs or to any part of the MG. So If I can bring down the cost I'm better off. If you can fix it use it.

The cost is nothing for me to drill. ream to size, turn down a brass plug and install. If I had to send it to a shop then that would be another matter. I had looked into casting my own but its benefits outweigh its costs.

John,
As you’re doing a lot of rebuilding of these things and have a pile that you’ve saved, it makes perfect sense to jig up and rebuild them. The time spent developing a drill press fixture and rebuild your “ pile” will be time we’ll spent in the long run. Of course it doesn’t make sense to us that might need to replace them once every ten years, but in you’re case.....go for it. I also hate to dispose of usually superior original parts that can be repaired. Good on ya’.....

Rob,

Thank you, I reamed out the smaller holes. After letting the 1/4 stock I turned down sit in the freezer I pressed them in place. Nice and tight fit. I haven't any 3/8th brass stock laying around so I'll have to get some then do the larger hole. I'll see how they work out this summer when I put a set on my car.


Just to let you know that I plan to use them on my own stuff only. That and on the freebees I do for real close friends.
