Thanks, back to the basics. If all the systems are not correct fooling with the carbs is a waste of time.

Hoping to get this issue cleared up and then on to setting the Webers up. We have an Innovate LM 2 with the tail pipe adapter. Has anyone had luck with this setup? I have never used it, but does look somewhat confusing. We will not be using the OBD function or the RPM function.

Does it have a way to just monitor air/fuel ratio? Commonly referred to as AFR.

Yes, I need to learn how to operate it.

BTW: I have a flip phone, no smart device for me

I know nothing about the Innovate devices but capturing the AFR and RPM simultaneously is highly desirable.

I would say it is essential for setting up carbs. Even on a dyno where you don't have to steer or brake it is hard to determine at what rpm an AFR dip or bump occurs by trying to simultaneously monitor the tach and the AFR readout.

Cheap soft mounts are very expensive.

Buy the best quality you can find.
Trust me on the Franck VF tube concept. Changes the entire thinking around Webers. Frankly, his explanations suck. But the tubes work.

I have an Innovate AFR and use it both bung-mounted as well as with a tail pipe adapter. The tail pipe adapter can be less accurate at idle due to reversionary air flow contamination.

But under driving conditions I’ve found both mounting schemes provided consistent info. Makes tuning carbs much easier.
