I was hoping this would be the case. Maybe it's turned out to be difficult because I'm a nube...
Anyways, I've got a couple issues i've encountered tonight. The idle was originally running high - around 1200ish. I was able to get it down to 1000 by adjust the idle switch (still a little high). After driving it around for an hour or so, the idle suddenly dropped to around 500. I didn't yet try adjusting it from here. I also set the fuel quality switch all the way to the left (counterclockwise), which I believe is the 0 marker.
After calibrated the LM-1 and began with readings at idle (1200ish) around 20 AFR. I began adjusting the rrfpr with the vacuum line disconnected (felt like there was plenty of vacuum) and adjusted the on set screw clockwise, increasing the fuel pressure. This seemed to drop the AFRs to around 17. I increased the fuel pressure further but it seemed to have a counter effect, increasing the AFRs to 20. I eventually settled on the 17 AFR and took it out for a little drive. As soon as I gave it a little throttle it jumped to 14 AFR and to 10 AFR on moderate throttle.
I couldn't get past 3500-4000 RPM in any gear. It accelerated slowly to this point and then started running roughly and no more power. I'm going to verify that we're getting spark at all plugs next.
Any advice? This is first time tuning anything. I'd appreciate any help you guys can give. Thanks.
