Post subject:  Air fuel meter recommendations

I’m thinking of buying a air fuel meter I can use for checking the tuning of my carburettors.

Can anyone recommend one?

I was looking at something like this,

I use an mtx-l, have had no problems. I set it up in a Jaycar box so it's portable.
Have done a couple for other folks here.

How do you attach the o2 sensor?

The kit comes with an M18 spud fitting.
I welded a nut to a 9" length of 20mm steel tube with a clamp bolt. Tube sticks up into the tailpipe. Copied from the fitting that came with GR's Innovate LM 1.

Edit
It won't read at idle because of the air choofing in and out with a decent cam in. But once you give it throttle it's fine.
