Couldn't find that thread. However, I confirmed my belief by looking at my parts books that the AJ29A was on KF7's which were the Super 10's. AJ36A were the carbs on the KG4's. The KG4H's even came with the 36A but eventually the 32A which was on KG7's were allowed.
The 32A's were allowed when the 20H came out which obsoleted the KG7H, so Merc came out with a kit comprised of block & pistons to convert KG7H's to KG4's for racing. Perhaps the confusion on the thread is a result of the KG7 to KG4 kit was actually installed on a KF7 with the 29A carb.
