It failed for the 3rd time. Luckily the smog guy is cool and has manual moded the last 2 tests.
I have changed the cat, the plugs, the carb, the gas cap, the oil, ran a bottle of Sea Foam and...installed a rebuilt carb.
I changed the o2 sensor 2 years ago. I guess that could be bad.
The carb is a rebuilt of the original and bench/flow tested before I get it. It was set to oem specs.
The timming is 8 like what it asked for underneath the hood.
these are my results
15mph HC (PPM) 239 Co 3.77 No 109
25mph HC (ppm) 168 Co 1.31 No 181
I guess the carb is running rich. I have no clue to adjust one of these mikuni sonex carbs. I was able to adjust the idle but thats about it.
Anyone know how to lean or rich it out?
Thanks in advance
