Ahhh, Thanks Grumpy and now I appreciate Jaffa's point a little better too.Unfortunately it's hard to see fuel coming out the venturi because there is a metal guard across the intake area. I think it's the original prime system. It all seems to be good now as it does start first pull with everything back in place...and a couple of primer presses. I repaired that gasket with some aviation gasket goo. Seems to have done the trick. Thanks to all for their help.
