RE: Change fuels - re-tune engine?
OK Troy......you're batting 1000. The tank made no difference, you thought it wouldn't. Here's the latest thing.....the fuel tank is not getting fully pressurized, not like it used to. I took my bicycle pump and gave the system a shot from the pump. The whole system pressurized and help pressure, so that tells me the check valve, tank and lines are all tight, the only thing left is the engine. (120AC). I sent an e-mail to YS parts and service, guess I'll be sending it in for an overhaul.
Thank you for your help. I'll let you know how I make out.
