1987 318 Tuning with Summit Carb

I haven’t seen a carb like that in 10 years or so and I forgot exactly where the IFR is.

If you can get to it to drill and tap it you can change it.

Did you ever get a measurement on the idle air bleed?
I don't have a way to accurately measure. Wife and I decided to try a new bar tonight, so I didn't swap the carb back on. Tomorrow I'm headed to Carlisle. So I'm on hold.
