MFI tools
 

Can anyone comment on how the MFI tools sold here compare to coming up with your own to do it? I've used a bunch of 1/4" drive extensions connected together. While it works, it's not the easiest thing to use, but maybe it's just the nature of the beast?

Thanks.

i went ahead and bought the tools (air flow meter, long screwdriver, long hex nut, long socket) just to make things easier on myself. i've never regretted buying them because i have used them over and over again.

biggest investment for me was a gunison gas tester ($125??). that was vital to getting idle mixture set correctly.

I recall that the MFI adjustment procedure made use of protractors. Anyone ever use these? Are they worth trying to find used, or worth fabricating based on the original tools' design? Thanks.
