I have a 1959 35 hp. johnson. I want to install a tack to optimize the engine.It has a electric start but no generator.It has a standard ignetion,points ,cond. ,camshaft.after checking it appears the only tack avaiable are the ones you wrap a wire around one spark wire for the read out.does it work on any no. of cyl.( 2-3 -4)and are they accurate or just another toy that may or maynot be at best a reference point but not the actual RPM.
