Dragged my Victa V40 engined Honda mower I made out of the shed today. Since it has always run a bit fast at full throttle, I gave the outer adjustment screw a turn in to slow things down a bit.
Doing this made me question what the inner screw actually does. I am guessing it is something to do with limiting/extending choke movement, but have never seen anything specifically about it.
Anyone know what it's for? Guessing it would be the same for Honda GXV.
