I made a decision to buy a set of HIF6 carbs from Tradera a few months ago and finally got around to mounting them on my B20. Well, the front carb seems to work as planned but the rear started spewing fuel from the overflow tubing/hot start area. Also then noticed that no matter how much I screwed in or out, the jet wouldn't budge from well below the flush level.

I'm also at a loss to what model these carbs are. I'm assuming they may not be matched at this point but I'd like to get a rebuild kit for it. Is there a way to determine the model or year of the carbs by looking at it? The metal tags are missing from the top. I was told they were rebuilt...guess not.

Ugh, foolish me!
