Gaskets
Trying to get a set of gaskets for stripping down the carb on, what I suspect is, an early 90s Qualcast 35sk. I've tried the place in Gateshead with no success. Any other ideas?

Struggling a bit but of the three possibles, Dellorto, , Walbro/Tecumseh and Tillotson, I can only eliminate the Dellorto.
Going to do a bit more research but meanwhile please give the carb a close examination for any numbers or even a name cast or stamped into it
EDIT
On second thoughts and looking at the shape of the choke lever, I think that it may be a Tillotson.
The bowl gasket would be Atco Qualcast part number F016Q10076 ( Tillotson No. 16-B388X ) and if you cant find one through the usual channels, try Jon Cruse at the Hailsham Mower Centre 01323 842477 or Hugo at Rowena Motors 01248 715552.

Which does look remarkably like the Tillotson logo
Does look fairly approximate
Does look fairly approximate ! I’ve neither a Tillotson carb nor a good enough image to do a detailed comparison but I think that we may be on the right track.
Got the appropriate gaskets
Got the appropriate gaskets from JAPG-mowers and stripped down and cleaned the carb. Was exactly the one in the PDF you sent. Thanks.
For anyone else doing this, a small pop rivet is the perfect calibre for tapping out the float fulcrum pin.
That’s good. I can’t
That’s good. I can’t recollect stripping a Tillotson , is that pin slightly tapered, making it only possible to remove it in one direction? The Bing carburettor on some JLO engines has a tapered pin which can be a difficult to remove while trying to support the carb while driving out the pin. My solution was to buy a cheap “automatic” centre punch and grind off the point to produce a flat surface. Then with the punch set for a low impact it became an easy two handed job - carb held in one hand, punch held against the pin and “ fired off” with the other.
I’ve obtained a couple of difficult to find parts from JAPG - they seem to be a useful firm to bookmark.
No. The pin wasn't tapered,
No. The pin wasn't tapered, just stuck fast.
My solution was to get a mate to hold the carb on the bench while I held the pop rivet in a pair of needle nosed pliers and gave it a firn tap with a pin hammer. Having an extra pair of hands is always useful.
The make of the carburettor
The make of the carburettor and an image will help.
