[Healeys] SU carb reamer needed

[Niels Bengaard]

I had a machineshop ream my HD8 carbs and rebush them 5 years ago.

I recall they say in the manual that comes with the set that you aren´t supposed to drill straight through, but drill from both sides and leave some material.

That took a bit more time to align, but it was possible. He used a reamer for both the outside of the bushes and the inside.

Get standard bushings and have a local machine shop drill the body and insert the bushings or insert them yourself.

With adequate resources it's clear that addressing both the shaft and bushing would be the optimum solution. However as an impoverished student over 50 years ago I recall changing out the throttle shafts on my Sprite, at minimal cost, convincing myself that this made a difference! Joe Curto wants around $500 to rebuild a pair of SUs. Now as a retiree I have more resources but still need to manage how much money I spend on my hobby.

 

If the wear is limited, maybe shaft replacement only might be cost effective?

Might be a better idea to send out the bodies to someone like Joe Curto and have them reamed and re-bushed for a standard shaft.

I have H6 carbs on my 100 Le Mans and the 5/16" throttle shafts are loose.  I would like to go ream out the bodies and go to the oversized .320" throttle shafts.  Moss wants $270.00 for the reaming tool and I do not anticipate I will need to do this job again during my lifetime.  Does anyone have one of these they would be willing to loan or rent?
