Re: Force 70 hp 3 cyl
Im sure others can define 2 stroke in a simpler<br />terms but:: A 2 stroke fires every 2 strokes or<br />one revolution.A modern 2 stroke requires oil<br />to be mixed with the fuel for librication.<br /> A 2 stroke has few moving parts Basically<br />the piston,connecting rod and crank.3 moving parts<br />per cylinder.A 4 stroke has many moving parts<br /> piston,rod,crank,cam,2 lifters,2 valves and valve<br />springs,cam follower,oil pump.<br /> 2 stroke used too have efficientcy and polution<br />problems but modern 2 strokes do very well.<br /> probably too much info.
