I spent about 5 hours yesterday step by step tuning and trying to get the engine to run but to no avail. As soon as I try to go WOT it sputters and dies and the fuel leaves the line and runs back into the tank and the engine dies. I checked for air leaks and used RTV sealant on the muffler to make sure I wasn't loosing pressure but no luck. MY LHS has a OS .61FX that has been sitting on their shelf for almost a year and the guy dropped the price to 120.00 so it looks like my twist will be getting a boost in power this Friday. Any other Evo owners out their had a similar problem?

Thanks,
