How’s she sounding? I put 1 tbsp marvel mystery oil in each cylinder. tested both pumps prior and fired right up. was the MMO the reason it fired up? because it stalled out i’m guessing to no gas. I put 5l premium gas in the tank after cleaning it and replacing pumps.

 

The MMO probably helped the cylinder compression to the point that it compensated
for the possible bad/old gas. Check the Shrader valve to see if your pump is providing
adequate pressure. It is good you are replacing the pumps and removing the old fuel.
