Thank you so much for this video! I tried two types of cork, switched to felt and eventually found the teflon you mentioned (Moss had it the whole time) and FINALLY my H4 jets are not seeping fuel. Seems the cork seals even in the Burlen kits – with new jets/bearings – is no guarantee.

THANK YOU .put the teflon in ,polished eveything even pistons  and needle ,8 or 9 flats out and the TR4 is running better than it ever has , and No fuel leaks

I know I am 4 years too late, but I would guess that the fuel level in your float bowls was set too high and the forks that shut the fuel flow off needed adjusting.

Did you soak the Cork seals in oil prior to fitting? That's all I can think..

Thanks for posting. I have an MGA car here with a drip from the bottom of the jet.

Thanks Dabiv, great video! pls can you help me sending the part number for the kit. I would like to buy it by ebay for my Riley 1,5l 1947. Regards from Argentina

Awesome guide! Quick question: did you have any issues with the main jet leaking? Mine stays damp and I can smell fuel in the cabin. I noticed I can actually move the jet side-to-side by hand—is that normal?

Once mine is in place on the car the choke lever operation is then tight as the jet moves down and doesn't return on its own.. Any thoughts ? The glands are new and oil soaked.

This is even before the damper is fitted.. does the cork need some time to free up ?
Thanks
