DanTM Posted October 25, 2021 Report Share Posted October 25, 2021 Hello All, This is my first time using the forum for a questions, here goes. I had a fuel leek when trying to set the su carb mixture on my 1955 TR2, as idle problems, but gaskets old and shot so petrol dropping from the bottom of the mixture nut. When taking the jets out during the rebuild to polish and replace gasket set, there was a difference between the two carbs, one side had the glad gaskets and brass gland washers either end of the gland spring. The other one just had the spring, no washer or gaskets. Is this some sort of different jet set up,or is it a bodge (my first carb rebuild). Any thoughts appreciated. I have not replaced the needle or jet as the car was running ok if idle wasn't great. Regards Danny Quote Link to post Share on other sites
Lebro Posted October 25, 2021 Report Share Posted October 25, 2021 Does this help? http://sucarb.co.uk/technical-h-type-carburetter-diagram Bob Quote Link to post Share on other sites
DanTM Posted October 25, 2021 Author Report Share Posted October 25, 2021 Cheers helpful diagram. So I take it the fact the car ran for the last 10 years without these parts in one of the carbs, these should be in place as per the digram, but clearly not essential to run th car.

Lebro Posted October 25, 2021 Report Share Posted October 25, 2021 I don't know how the errant carb managed to not leak fuel everywhere ! Quote Link to post Share on other sites
DanTM Posted October 25, 2021 Author Report Share Posted October 25, 2021 I know I guess the metal parts must have been a nice fit, but the larger cork washer on the outside was enough, but I had never seen petrol drop over the past year since aquiring the car. But agree not sure how it lasted. Quote Link to post Share on other sites
Paul Parky Posted October 25, 2021 Report Share Posted October 25, 2021 I replaced the large cork gasket with a suitable rubber o-ring when rebuilding my carbs. The cork gasket had dried out and was leaking fuel. As long as you apply a small amount of lube to the o-ring it will seat well and seal. Quote Link to post Share on other sites
