  View original topic: Single Carb Zenith on a 2.0L T4

I'm doing it with industrial intake end castings, a T1 center manifold and running heat risers because... why the f*ck not.
Anyone have a suggestion on jetting? I've got a 0 mile rebuilt Zenith jetted fat for a 1679 currently.

I suspect you'll be the owner of an AFR meter and a box full of jets soon, that's really the only way to dial in a mystery combination like that safely and efficiently.
Good luck, sounds interesting, please post the results.

Jets are NLA. Everyone with any kind of stock on them only do a cash plus exchange basis so I need to know what is required. I've got the meter.

You pretty much need to start by knowing what jetting you now have and how the the carb now performs. I would guess that there may be jets available new for some other application that fit your carb. Can't say what they might interchange with though.

Or get your grubby hands on as many small jets as possible - and some jet drills to enlarge the hole and start the experiment.

This sounds like info from a story I read in this book while on the pot :lol:
