mfi adjustment on '73S

I copied this reply from Tyson Schmidt from another tread. This is what I'm experiencing with my 2.4S. My mechanic set it to factory specs. Can I adjust this with an LM1, or do I need to put it on a 4-gas analyzer.

I think what you might be experiencing is the fact that you have to set the part load mixture pretty rich for it to run right. If you set it to factory specs, it'll have poor driveability and a flat spot around 3000rpm at part throttle/part load.

When I use the 4-gas analyzer, I set them at 8% CO at 2500-3000 rpm free rev. That usually gets it right. MFI gets leaner under load, so you have to compensate.

I just remember 5-6-7-8

5-6 for idle
7-8 for part load.

I have an LM-1 with the bung in the muffler inlet, works fine.

Again, others more knowledgable than I may offer advice. Tyson is one of those persons. . . Grady is yet another. . .
