I see no reason that would make a difference. Once I get it to start with the spray can it will idle perfect for as long as I want. Exhaust doesnt have a bad smell like if it was burning bad fuel.
As a side note, last year the last time I drove it was right after buying it for my son and I had just rebuilt all the brakes,new tires,new coil,wires,plugs,fixed the broken EGR tube and new battery installed. I moved it around my driveway a few different times with no issues this past summer.However it became a no start issue out of the blue about 4 months ago.
