Hi All,

has anyone used Fabre/SU Midel to overhaul their SU Carb?

I have put a kit through mine but i think the shaft bushes are a little worn, but before i commit to them for the $300 odd dollar rebush and service kit (service Kit out of UK last time for the HIF Turbo carb was around $80 bucks) so its not too bad a price i guess.

anyone got reports of their work?

or i can get this

Ive done both, had SU Midel service a carb, and rebuilt my own.

I always felt it was an AWFUL lot of money for very simple work. The only challeng part of overhauling a carb is overdrilling the spindles to accept the white metal bushes. Saying that it only takes a gentle hand or asking a machinest to do it for you. The only real trick is making sure you push the bushes in all the way through to the carb throat and then using a fine file to get them to match the curvature of the throat to prevent air getting past the spindle.

I've rebuilt every carb I have owned ever since. You are rewarded with a perfect tuning carb, and a car that stays tuned.

I used Carburettor Service Company in Burwood....

http://www.carburettorservice.com.au/

highly recommended if you want to pay someone to do the work.

Can the bushes be purchased loose? yes.

I THINK I picked up bushes from minispares, but may be mistaken. I usually buy the complete kit because I will baseline the whole carburettor if I am going to the trouble of rebuilding it.

I like them shiny so I blast the lot and plate the loose bits, but is it absolutely necessary....no.....but it looks special.

You can buy bushes and spindles from Burlen in the UK.
they are cheap.

Google SU uk.

Always wondered about drilling out for new bushes, is there a chance you can drill off centre ? coz the original holes can be quite oval. If they are off centre wouldn't the butterflies not close properly ?

The butterfly can be adjusted in the shaft (a bit) because the 2 screw holes are BIG.

Sometimes I have found that the bushes have not quite lined up perfectly when I have pushed them in. This makes the shaft a little stiff initially. All it takes to fix this is to spin the correct size drill through the bushes to take a high side off.

It doesn't affect the hole size, just the high point of an imperfection.

What a rough cost of having an su serviced/rebuilt from these guys

I just dragged out the receipt and they overhauled and adjusted the carbi, repaird the throttle action, repaird the choke and fitted an inline fuel filter. Parts included a repair kit, 5/16 x 3/8 bush, metering pin, t/disc 1.5 su, screws, filter, clapm, hose. Labour was 2 hours ($100 per hour). Total cost = $321.90 inc GST.

Car ran and continues to run awesome.
