3 deuces cars used it as well then. I have thought of other leaks that might be beneficial in a similar way without changing or raising idle mixtures. My head is still stuck back then in many ways, in my thinking.wwmtlineman wrote: ↑Fri Jun 15, 2018 11:51 am Worked back in the late 60s for NHRA stockers until they caught on and used a sniffer to check them. A lot of 2 barrel cars slowed down after that. They would idle around in a black cloud of rich mixtures
just enlarge the power valve fuel feed drilling and it will not affect the idle richness as you are only looking to richen up wide open throttle.Fireonthemountain wrote: ↑Sun Jun 17, 2018 12:46 pm3 deuces cars used it as well then.
