Straight connector 1/8NPTx6mm brass (burtonpower.com) That was me though I think it was mentioned in your members cars thread John? Can't remember now. Over the last few nights I've been messing about with fitting a screw in barb to a carb top while the nights are long and the days are short. My barbs were very tight in the carb top and I've left the return outlet alone for now, but bit the bullet and did the deed with the inlet pipe. Here's what's left of the brass fitting after mucho messing about. This is the point of no return, so had to crack on and get the rest of the brass fitting out of the hole. This probably were I am a tad lucky as I have a small tub full of reamers and I managed to get most of the brass fitting out. Then I used a 9mm drill bit to drill the hole for the tap. In the last conversation regarding this topic it was mentioned to use a 9.5mm drill bit but I used a 9 and it tapped pretty well. Bit of removable thread lock and hopefully this should be ok. 1 Quote Share this post Link to post Share on other sites
martog 128 Posted January 22, 2022 Bought this kit from Top Performance which comes with a powervalve and an extra gasket so that it opens up waaay more than the original. Moar POWER!!! Excellent! 1 Quote Share this post Link to post Share on other sites

Apologies, I got the company wrong. Should be Total Performance NOT Top Performance. £29.99 posted though they forgot to add the accelerator pump diaphragm in my kit. Not too bothered about that since I rebuilt the carb only 3 years ago using the Weber kit so it should, in theory, be ok...

martog 128 Posted January 23, 2022 So fitted the powervalve and it's gasket to the carb top along with the gasket that goes between the carbs two halves and fitted it to the car today. This is the scary bit...You need to push the carb top onto the bottom bit whereas before you just drop the top onto the bottom. This opens up the valve that sits in the bottom of the float chamber and will no doubt opens the powervalve so fuel is now dribbling into the secondary choke even though you don't need fuel there until you plant your foot to open up that second choke. Yes, it works and doesn't mess about when you rev it up to open the second choke, I just don't like the idea of fuel disappearing down a hole when it not needed. So next weekend I'm going to remove the powervalve gasket (not the diaphragm) and get the engine running and see what happens then. Quote Share this post Link to post Share on other sites
