A---" crossflow "-- has a deflector on the piston crown to direct incoming charge to scavenge the cylinder.-----A looper has a flat / nearly flat crown and intake ports positioned to loop the incoming charge.
These " holes " in the cylinder are also found on bigger motors including V-4 and V-6 models.-----People often state that a motor has " good " compression.----But many have no idea what it should be !
I picked up a 6 HP Johnson for next to 0 beer tokens.----Tag says ---" low compression " ----as reason it was set aside.------I tested it at 90 PSI.-----Doubt there is an issue.-----These motors have a hole above exhaust ports.-----Bleeds off compression at low speed.-----Makes for smoother...
Many motors with small problems end up on the market.----Bonus if you know motors and simple trouble shooting.----Many dealers now frown on older motors because the owners are not an easy source of revenue.-----Older motor give you years of low cost boating if you learn the basics.
