I HAD4bbl carb rebuilt last year, was getting a gunk in them from mtbe& methanol residues plugging tranfer ports(midrange circuit), made it 14 years, never quit but transitioned badly from idle to mains.
always had preservative,clean filters (2) and full tank.
filters are only part of job.
hope carbs do it, should last long time
only ran 12.9 gallons sat ,going to fish thursday and expect to burn 20-40gal .
its going to get worse as i cant get ethanol free fuel and e15 is comming.
Deathanol to boats fuel sytems.
