So i’ve been working on this sled for awhile now. I cleaned the carbs and fixed all fluid lines and it ran very well. I went home for break and came back and it won’t start. I replaced a bad spark plug boot and both spark plugs. I also tested the plugs with a tester to make sure it was getting spark and it is. It won’t even sputter. I’ve run out of ideas at this point. Fuel is running through the lines as far as I can tell.
