The engine ran fine yesterday. Today I swapped the low speed jets from 115's to 117.5's and now it won't run. If I prime the engine it will run for a second and then shut off. My supply line is going into the bottom fittings on the carbs and my return is coming out the top. When I'm cranking the engine, I can physically see fuel going into the carbs and then going back into the tank via the return line. The pulse lines are hooked up as well.
Since all the lines are correct, could I have screwed something up in the carbs when I put them back together? I'm at a loss... The fuel filter and primer lines won't stay filled but they don't have a leak. The check valve on the tank appears to be allowing air out of the tank as well as in but I've fired up engines with the gas cap off so I can't see that being an issue.
