Does anyone know if this can be used to seal between carb and inlet manifold, ie dies it resist petrol? There's nothing on the data sheet on their website.

id imagine itd do the job, but wouldn't like the possibility of bits of silicone going into the valves, and compression chamber, just my thought,

Can you not use the standard gasket?

Sealing for Oil and Fuels is usually a special property and one that would usually be high lighted if it were. I'd suggest it isn't.

I know it's used for sealing in between the block and gear box. Still got a fuel leak between my Weber and supercharger and I have an MOT on Saturday. I'm waiting for some sikaflex 221 to arrive but it may not get to me in time

Faces must be clean and flat. I always use a new gasket and smear a bit of grease on each side - the theory being as you tighten the mating faces together the grease allows the gasket to settle into place evenly.

Can't use a gasket. This is for the gap in between a Weber and a supercharger. The alignment is slightly offset so a gasket is no good.

should not be needed with the O rings and Thackery washers.

If it’s between the carb and SC what about Misab Plates??

I got rid of the sikaflex on my charger as when I took it apart there was a lot that had squeezed out and was blocking one of the pump jets
Refitted with misab plates now

I would like to use those, the alignment is slightly out, so the bolt holes on the carb have been milled out to fit the flange welded to the charger. There might not be enough meat those o ring gasket things to enlarge the bolt holes

is yours a vmax kit? And if so were the holes on your carb opened out a bit?

I've ordered them now. For the sake of £8 its worth a punt. The sikaflex has arrived today, so I'll whack that on for the mot and when the Misab plates arrive, I'll swap them over.

On my old RS2000 running twin 45’s I swapped from O rings to Misab and the difference was light and day. Yes Thackeray washers when set correctly should prevent leaks but I had constant problems.
