Hi chaps
I've got an 1 1/4 SU that I'm planning to overhaul everything seems ok except the spindle. Its pretty loose. what wears out the shaft or the hole and is it expensive to fix?

I am pretty sure both can / will wear. The shafts in my twin HS2's were worn .020".

Classic motoring in the ACT sell rebuild kits that include new shafts. Good value, good kits.

They both wear. Mine had to be drilled out on the body to the next size and it had larger shafts fitted. I think you can use the standard shafts with a bush to take up the wear but I would only do that as a last resort.

They work nice and I would recomend you getting your carb rebuilt (it'll be worth it).

There are a couple of rebuild kits - basic and more extensive. Check that the one you get has the inserts (spindle bearings?) to fit the spindle properly. A bit more fiddly to install as the holes have to be accuratly drilled and aligned but worth the effort.

$180 is a great price. I was priced min $240 a carb the other day.
Got a kit for $116 and am going to give it a go myself now.

just take your time and get everything spotless.... the choke levers are an odd little setup with a screw, sleeve, spring and some washers, so take some photos, and make notes about what goes where. Also, if you do one carb at a time, you'll have the other one to refer to when you get confused.

and one important point, when it comes to removing the bowl from the carb, and the odd shaped rubber that goes between them, DO NOT TWIST IT there is a little locating lug which can and will break if you twist them apart... drilling a hole in each side and aralditing a pin between them isn't a fun job :roll:

On the topic of this.....

Is it recommended to purchase the SU tools from the classicmotoring site?

I've done 3 without special tools so can't say if having special tools helps - I certainly didn't feel handycapped in anyway :wink:

Yes you don't need the tools but they can be helpful. I've never bothered myself as I already have a socket that fits the fuel float valve, which is the main tool you need.
