OK guys, good news. I tore it completely apart trying to decipher just how this carb works. I spent NUMEROUS hours of poking & measuring depth of drill bits into all the holes under the lead plugs. Rather confusing.
Apparently this carb is vented out holes on the front (thru slots) under the breather. However there were no holes out the upper part into the float chamber. One hole went straight down to withing 1/8″ of going into a flat boss in the chamber. I just drilled it deeper & into the chamber. Then replaced all the plugs, and reassembled. It did not flood and started on second pull.
I am still unclear as just how that was supposed to be vented, but IT RUNS.
On all the other OMC carbs that I have worked on there was a vent hole somewhere on the upper outer part of the main body. Like I said, there will be a big mark on my shop wall for this one.
Than you frankr, maybe someday we can get together for a beer.
