if you didn't treat the fuel prior to storage,sounds like bad gas still running through.dump in some seafoam or other good fuel system cleaner with your fresh gas(depending on what you use ,you may have to put in 1st then fill up,or may have to fill up first with gas then add additive)

sounds like bad gas the quality of fuel these days isn't the greatest. or water in the gas. If you didn't have a full tank over the winter condensation could build up. You can try some heat gas line anti freeze but ration it for your size tank a bottle treats like 20 Gallons.

Ooops, 1/4 fuel left 3/4 empty and that's your problem. Condensation forms everytime there was a temperature change in your unheated garage. Not only do you most likely have water in your tank but you also have the start of a rust buildup. Dump the old fuel. Best to remove the tank and get rid of as much as you can. Fuel up with Caltex, Chevron, whatever has Techron in it and you should be good to go

I'd also pull of & re-seat the spark plug wires.

My biggest fear is when I die, my wife will sell all my guitars for what I told her I paid for them.
