Float bowl spacer

Hi guys - the HS6 carbs had a rubber (?) spacer on them that I've not seen on other HS6 before. They were dry and crumbly, and generally broken-up so I discarded them but now I'm wondering if they need to be replaced.

There was an extra spacer where part #10 goes;

"...so I discarded them but now I'm wondering if they need to be replaced."

Yes, they perform two functions: 1) they isolate the float bowl from vibration and 2) they set the float bowl at the correct angle (level).
Cheers,

Jimmy Hilton is a guy in Texas that rebuilds SU carbs on the side and does excellent work. They come back turnkey with little adjustment needed and are better than new at reasonable price. I currently have one of my Bee's carbs being rebuilt by him. He did an excellent job on my Cee's carbs and I highly recommend getting yours done by him. It makes all the difference getting the dizzy (Jeff) and the carbs (Jimmy) in getting these engines running without a bunch of guess work.

Hilton is the like the Jeff Schlemmer of SUs.

Or is it the other way around?

Have heard nothing but kudos for Jimmy's rebuilding services.

Hi guys - turns out that Moss carries the spacers.

Robert Edwards has saved me from me (they really were shot) and took all the mystery and work out of this (thanks Rob!). They are Moss 372-670 and 372-680. References to Healeys.

Mark S - maybe something for the newsletter? (that I still need to send you money / paperwork on)

Just did a test fit of the Volvo carbs that i rebuilt for Tom R's 122s and they won't work as temp units on the MGC because I forgot that the Volvo intake manifold is at an angle. The float bowls are offset on the 122s carbs to keep them level, and when mounting on an MGC they'd be at a weird angle. Oh well..

Now where did I put that spare HS6 main body?

Tom:

If they are also HS6s you just use a different float spacer - OOPS! -

That reminds me that the Healey carbs are all 30 degree semi-downdraft types, so the Healey spacers will just make your MGC carbs into Volvo carbs. Better recheck those part numbers again.

I have used the HS6 carbs. off a Volvo by changing the float chamber adaptor (spacer #10) from the one used on a Volvo to the ones used on the MGCs. The angel of the rubber adaptor was different on the Volvo carbs. I had which held them at a slant just like you experienced. Also these adaptors are handed so they only have the correct angle if installed on the front or back carb. they were made for. The originals I have seen were one blue and one red so they would not get mixed up. I just don't remember what color went to which carb.
Hope this is of some help.

Got the broken shaft out of the original carb body, so maybe I can scrounge up a replacement pivot bolt and get back on track here.

Would it be the same one as in the HS4 b carbs????

Not sure - good idea though Swamper! I don't have a set of HS4's handy to check, but I'm staring at a pair of HS2s right now and they sure look the same.

I have a spare set of SU HS6 carbs so if none of the guys have one locally I'll cannibalize the spare set. Shhhh. Don't tell Tom R since it was going to go with the car once is comes to his senses and buys it...

There is one other issue to be aware of in the difference between the normal 20 or 30 degree float bowl mounting, and the horizontal mounting. In SU carbs that have horizontally mounted float bowls, the bowls are also different. All bowls that are for non horizontal mount will use an 1310 bowl. All that are horizontal will use a 2140 bowl. At first glance they look to be the same, but are not. The 2140 bowls sit lower in relation to the carb body. The jets and choke lever setup are also vastly different for a horizontal mount bowls to accomodate the shorter distance.
