Well, Guys,

I just got back from trying out the suggestion to shift into low to start and see if that made a difference. It did not. I will check for that adjustment screw and also look to see that the exhaust is open and there is no air restriction.

The other thing that I will try is to replace the fuel filter and make sure the fuel lines and the banjo bolt are clear.

I did notice that at idle, the oil pressure went down from three to two but as soon as I stepped on the gas, it went right back up again.

Thanks for all your help.
