Thanks for your reply. How do I remedy the lean condition at cruising speed? Can I reshape the cone inside the mixer? What are my options? also, does the converter mounting position have anything to do with it. As of now it is horizontal over the top of the right hand valve cover.
I just converted my 86 chev 1/2 ton 350cid 4wd to liquid propane, 425 mixer, model E converter (no computer) I installed a 1 wire bosch O2 sensor, connected a digital volt meter and I can adjust the idle mixture to about .5v, but cruising down a flat road at 50-55mph It runs about .18 to .20v...
