Does anybody know the size screw needed for the Dellorto 11752 it’s the carb assembly screw. I lost mine and everywhere has a minimum order. Hoping I can get one on EBay etc

Thanks Daz

If it is the countersunk screw that retains the choke mechanism to the main body, then it is common across a lot of the Dell'Orto product range.

If I am correct, it is an M4 (x 0.7) & not anything uniquely made to suit. Unless you need one precisely as OEM fitted for Concours, the best replacements are stainless socket countersunk screws as they look better & are far better to tighten/loosen with the hexagon key. If slotted head is a must (for some reason ) then I think the earlier version ia nicer, as it was a "raised head slotted countersunk screw" similar (but not M6) to the screws that should be retaining the handlebar RH lever housing.

Always fit the longest that is possible to ensure full thread engagement, cutting longer screws down if necessary as the carburettor body is soft metal, being a zinc based alloy.

I hope that helps. If I am correct & you still struggle, I have spares. Finding them might be a problem, but I'll post a couple if needs be

Great stuff. Found some on eBay
cheers

Not so much these days, I fear I was trying to get a seal/dust cover for an MSC hydraulic some years ago. I really only needed the dust cover as they tended to disintegrate.

The storeman just grabbed a load of seals & dust covers of various sizes & handed them to me......


As for the screw required, today I have to drill & tap for a stripped choke mechanism thread in a VHSB34LTD. Fortunately, it's opposite side to the mixture screw, so I can drill through then tap. The owner also needs a new needle & slide. He could have had a brand new PWK 34 plus all likely spares required for less money
