Re: 4 gal Evinrude tank, pressure or suction?

[JACQUES]

the air line pressurizes the tank whicht then forces the gas into the engine carb

to start the pressurization of the tank……. you MUST prime the carb by pumping the gas up to the carb bowl with the push button ( about 10 times) on top of the tank otherwise the carb will be empty of fuel and the engine will never start to… pressurize the thank

make certain the tank screw cap is tight otherwise you will loose that precious air pressure needed to push the gas up the fuel line.

before you start your oldie you should check your impeller..and gearcase oil

check your plugs (out & grounded) to see if at least you have sparking when pulling the starter rope

if it is a real oldy the coils are cracked for sure (if never replaced) you will need to service the ignition suystem … visit Leroy’s site and utube for lots of good info and videos. with all the info available here on this site and lots of coaching you can do it !!

changing the impeller is not hard but the fleetwin needs to have the head pulled off…to release the L.U. gearcase. that usually means getting a gasket for the base of the powerhead when reassembling .. most parts are available but figure on about 100-125 $ in parts for another 50 years of service….if the rest of the engine is OK

try to get a compression meter to measure each cylinder for at least 70-75 pounds… most like 80-90 and up but mine has worked flawlessly with 70-75 pounds
