I just ordered an adapter myself. I'll let you know how it turns out when It gets here next week. It is supposed to ship out tomorrow.
Edit: Other things I checked on mine, may help you out. EGR valve and its goodies, plugs and wires, O2 sensor has already been said, Fuel pressure itself (disconnect hose, Put in PB jar and crank engine, should get a strong flow) , clean the sight glass and look inside it. Its on the passenger side of the carburetor in the middle. You should see fuel around the middle of the glass. Remove the breather and open the choke, pull the throttle cable while looking for a good stream of fuel. I found mud in my float bowel but Narrowed it down to the absolute maximum.
