OK.................I replaced the fuel pump and that was 80% of the issues on idling and pulsating RPM's. I did spring for a new carb so all in all here is the low down over a few weeks to get it right:
I emptied and flushed both fuel tanks with acetone then cheap gas before filling with 89 octane pump fuel. I replaced every line and shutoff on both tanks, replaced the T connector, replaced the fuel filter needless to say and changed the air cleaner and still had a lot of air coming into the pump and carb from the clear line installed from the fuel filter. (Small bubbles into the filter, large gaps of air coming out).
I changed out all the small lines with clear Tygon tubing from the filter to the pump and from pump discharge to the carb fuel inlet.
Next, I changed out the fuel pump but left the original carb on and it idled without choking indefinitely for the first time since purchasing it this Spring. (Woo-Hoo). It still however pulsated slightly at WOT so tonight I put the new carb on it and it runs like it should finally.
Now I can get the stripped out bowl screws out of the original carb and get it cleaned up and ready in the event the new carb starts going south. This weekend, it gets AV-100, (Aviation Fuel/No Ethanol), in each tank to lessen further the chance of it repeating these same issues and to see if the tinted red gasoline at the very end of the fuel system goes away. (Fuel in the tanks is not discolored).
Sorry for the long thread but it may help someone else with a twin GXV Honda. Thanks for reading!
