Thanks Guys. In process of rebuilding carb, tanks has a little gas left in it. ugh!!! nasty. Soaking sediment bowl/cutoff with PB, havn't been able to remove it to drain tank yet, will need to replace gas cutoff. Appears to have a small drain plug in tank just forward of sediment bowl.
Thinking about temporarily removing oil pressure send unit in order to plumb a gauge.
Owners manual on the way.
