Get a new one. The relay feeds power to the dpm , ect...
Dpm goes full rich with out power.
The running rich gives it away.
Keep a spare as even just water ( like no cover on a open trailer , go to start it to drive off the trailer and it was fine when loaded )
Buddys had his screw up last year , he bought my old rev for his wife.
They switched relays for 3 days lol. Got her up to the top , goes through gas like crazy.
Update... Took it in for check up. Carb clean and v force. Called after these were in and had compression issues. 100 and 70. Not good. Pulled pots. Needed pistons, pots, they checked it out further.... Crank wore past specs. Picked it up tnite( Friday) headed to vale Sunday ... Put fox floats on,ripped across field and now got a coolant leak. Fkn choked!!!!
