What colour is the float bowl gasket on the 30 Evinrude ?----Black or brown?----If brown , it will stand up to modern fuel.----Just run carburetors dry when motor is not in use.
I clearly stated that you push them out.----Use the special factory " pusher ( i have a set ) or improvise with a nail.----Simple when you know how I guess.
???----It is a cast iron sleeve !!---If you look at the intake and exhaust ports you can clearly see that it is a sleeve.------The sleeve is not removable !----A ball hone will give you a " nice looking " finish and it follows all imperfections .-----A hone with 3 new stones will show...
Try the plugs in different holes.----The procedure is called indexing.----Use a torque wrench and do not exceed 17 FT LBS.----4 sparkplugs and 4 different holes , you should be able to come close.
There are some spray on gasket softeners.----Yes the block is aluminum.-----In the hands of a careful worker even a sturdy paint scraper will remove gaskets with no damage to aluminum.----Brushing some oil on the gasket may soften it up.
Pop the wire link out off the SLOW SPEED mixture needle ( white nylon piece ) set it 1-1/2 turns out.----Start motor and adjust on the boat in the water.----Slide white nylon piece off the needle.----Slide it back on pointing to the right and horizontal.----Re-attach link to the knob.
????--Nonsense -----It is the MIXTURE adjustment !!-------Idle speed is at the bottom of the tower shaft.----Ignore the " start " on the twist grip, turn handle to the neutral stop.----Check thermostat.-----They are often stuck open or missing.
Doubt it.-----Post your compression values here.-----Does spark jump a gap of 3/8" on all leads ?-----Replaced the water pump impeller about every 5 years?----Inspect exhaust under powerhead for blockage.
