Hello all,
I am used to working on classic fuel pump fed carbed machines, so this is a bit new for me. I am wondering where to start to diagnose the fuel delivery issue on this sled. It fires up for a bit with starting fluid, so good spark. I took the carbs out and cleaned what I could. I've uploaded a video with the sound the EFI is making (not sure if it is a normal sound or not). Owner said it ran good last year. and He has started it this year but it smoked like crazy. I already fixed that - the oil injector was stuck all the way open. That part operates as it should now. Any thoughts? Thank you!
