The other day on A post someone mentioned how they leaned out the low end just by using A glow driver. Sorry, I can't remember who or what post it was. Anyway, I had to lean out the low end on A Saiot 100 today and decided to give it A try. The idea is that an engine that is fat on the low end has the idle go down as soon as the driver is removed, very true!! You are supposed to remove the driver, if the idle goes down then put the driver back on and lean in the low end screw, remove the driver again, repeat until the idle no longer goes down and the low end is now in tune. Well, what would have taken A lot of time using A Tach and mark one ear took only A couple of minutes today!! I thought I had been taught every way there was to tune an engine but this one takes the cake!!! Just way too easy and worked perfectly. Whoever posted that last week, Thank You Very much. So far last week I learned two great tricks!! One on engines and one on covering. Just goes to show, even an old blind hog can find an acorn once in A while!!
