Has anyone used these with success , I was trying to figure out how you would get a baseline setting then fine tune from there, thanks for any info you may have.
I did a bunch of test-bench work for various Strommie components. It was aimed at the BXOV-1 carbs used in GM Holdens, but applies pretty well to the EE carbs - exactly the same main metering jets, and can use the same adjustable main jets. Disclaimer: I am not a fan of adjustable mains. They were normally used in taxis to chase fuel economy. To tune one for a taxi, wind it in until the car is fuel efficient, then replace the crispy-fried exhaust valves. Having said that, the safest bet is to run an exhaust ****yser on a dyno and check you are safe across idle, transition, acceleration, cruise and WOT. When you don't have access to an anaylser, the info below is a good starting point: As an initial tuning point, the following may be used: · bring the engine up to operating temperature, · hold the engine speed at around 3000-3500rpm (mid throttle). · Slacken the lock nut on the adjustable jet then screw the adjuster in slowly until the engine speed starts to alter and run a little bit rough. Wind back the adjuster until the engine speed pick up and the engine no longer runs rough. · Tighten the lock nut.” Whilst this is valid information, if you now roughly what jet your vehicle should have then you can use the info below as a starting point. I then put together the info below by wet testing a variety of fixed jets, and also two typical adjustable main metering jets: Opening Equivalent Main Metering Jet (”) Two turns 0.043 Three turns 0.061 Four Turns 0.067 Wide, wide open 0.073 Hope this helps.

Thanks for the info, I think I'll contact Clive at stromberg and see what sizes he thinks are best at our 4000 ft al***ude.
Clive is good people. Been a few years since I last spoke to him, but give him my regards. Cheers, Harv
