@ Alan,
No worries! The problem with the compatibility is that it quite as well might not recognize the ports properly. If you're not getting the error anymore, that is great news!
As for the fuel, the pumps that come with the engine are not really powerful in order to be lightweight. That's why they have some height restrictions with respect to the engine, along with the fuel tank. In case you have not checked it out yet, there is a chapter somewhere in the installation manual, where the height location of the fuel tanks is described. So if you have the engine on a stand, you might want to raise the fuel tanks at about a a foot from the starter. Try this, and see what happens.
And yes, keep me posted on your progress with this issue!
Thanks!
