Thanks a bunch for the input. Can you tell me how you would measure it using water cup. I am willing to try anything at this point. I have adjusted all types of carbs on gas engines but never tried lp. I dont know if there is something wrong or I just am not getting it right. I do have two regulators that were filthy and I cleaned them both out and of course because it had been adjusted for the filth I do not know if the settings were adjusted for clean regs or dirty ones. So I put them where they were but it did not run right. Thanks Rod
