Do you take out the old rubber gaskets and put hylomar in the groove instead or how do you do it? I'm afraid I'll block something in the carbs with the squeezed out sealant after assembly.

I used to recommend using sealant but you do run the risk of it causing blockages, though it never caused me issues in 3 years of racing.

These days I use Rick Oliver's replacement o-rings, only a few quid for a set of 4, bargain!

Shipping takes ages, so I only order from the UK if I have time and getting several things at once. Cammo did you leave the old gasket in when using the sealant?

Yes - i always left the gasket in when using the hylomar blue - but as cammo said, order a load of the o rings anyway, saves the mess everytime you need to open and reseal.

Dont do it, blue hylmor will turn blue jelly and gum up carbs, did it on my petrol tap few years back, never again!!

Personally, I would use Hylotyte Red (Hermetite), because it's semi hardening.

To back up what Abr and missis said - I did get some of the blue gunk in my carb bowl ! but i used to slap a load on as i was sick of the petrol peeing out ! if your careful, blue does it just as well.

a thin smear of grease to seal.

Same here red rubber grease here used to use hylomar but switched to red rubber.
