« on: October 24, 2018, 08:33:02 PM »
Can anyone enlighten me as to what the divots are for in two of the carburettor insulators?

They look to me as something to ease handling, hold between finger and thumb? :-\

Thing is only two out of the four have them. They are listed under different part numbers.

Ah yes Dave, I can see that now 🙄🙄🙄. Off the top of my head and without looking at mine, I don't know why 2 have those flat spots but I do know that the 2 outers are different than the 2 inner ones, slightly different angle and length if I remember correctly.

If you look carefully, there are numbers on them. 👍

The numbers are raised and are on the edge of the rubber where the butt up against the carbs. So in other words you'll need a giraffe's neck to see them and the carbs are also likely to block any view.
I fitted a new set to my 400/4 bought from DS. I didn't see markings when originally installing them and it was only after struggling to fit the carb bank when I looked again and noticed the faint, raised numbers. I think they were numbered 1 to 4.

All 4 of mine have a flat spot on both top and bottom, simple when you think about it, you wouldn't be able to get the screws in there if the flat spot wasn't there. No idea if mine have numbers, eyes not that good 😀😀😀

I've just had a rummage through my old parts box and found the insulators. Apologies for the poor photo but the camera wouldn't focus..... Anyway, the number is on the insulator to the right of the fixing hole. They are numbered 1-4. I assume they are fitted with the number at the top. This will mean you cannot see numbers 1&2 as they will be obscured but you should see 3&4 as they will be on right hand side of the mounting set screw.
