Blue sent a link to the FSM for these engines which shows an illustration for the L20A engine as having a single down-draft carburetor; did it come in both this configuration and the dual Hitachi side-draft carbs?

And this one; interesting if you have not seen it already.

By "cooling setup illustration", do you mean the water jacket outlet on the side of the head? You don't have that?

The L20A was also used on the JDM Gloria and 2000 models. These units were offered with the single downdraft carb.

I think that Kerrigan's quest may be to find out what's true and not true. How do you know?

Lots of conjecture out on the internet. For example, all of my comments in this thread about no need for L20A until there was L20B are wrong, if the information in the links in Post #21 are right. Apparently there was an L20, then an L20A, then an L20B. Apparently, according to the internet.

Yes, the water outlet to the radiator is on the carb side, above the distributor.

That has been the frustration. The people whose opinions are respected and admired have offered up different answers, in good faith, which has made this been probably one of the most interesting quests for information I've ever embarked upon.

It's been highly informative and interesting!
