| Post subject: | Rocker Arm Adjustment/Carb adjustment help |
I'm finally going to be driving my '71 Valiant around town regularly and I need to get the noisy rocker adjusted. They're manual adjustments right? Here's what I THINK I need to do: 1. Remove valve cover 2. start car 3. adjust rockers from #6 to #1 4. try not to get oil all over the place. 5. replaced with new gasket and valve cover. Second question. I passed the Colorado Emissions but had to do a quick adjustment because my Co2 levels were a little too high at idle and 2500 RPM. Got it to pass on the second try. The tech who did the inspectioin suggested a total carb rebuild, and to use a ( 1 size smaller)smaller jet for better gas mileage at altitude. He said I'm dumping too much gas and am fouling my plugs and oil faster than I should. I'm not getting good mileage at all. I have no idea what size jet is in there (Holley 1920) Any suggestions on either issue would be greattly appreciated. |

I had an 82 Dodge Ram with a 318 that I took from Oklahoma to Denver. When I took it in for emissions testing the CO an HC were too high. I replaced the jets with a size smaller and retested. It was better but still failed. Since I was moving the right direction I went another size smaller and it passed easily. |

Definitely rebuild the carb, which sounds like it's running way too rich right now (Holley 1920s tend to do this when they need a build), or install a new (not "remanufactured") one. As for jetting, you'll probably find something between a 56 and a 58 jet in there. Dropping down two sizes might not be a bad idea since you're at about 5,500 feet altitude. And run NGK # ZFR5N spark plugs without the metal ring washers. |
