Back in 1997 my next door neighbor said he liked my D series Lawn Boy so he picked one up at Lowes. I remember him saying that the new one didn't rev up as fast as my 1976 mower did. His was a V series with a steel deck. Twenty years later he gave his Lawn Boy to me because it caused him too much trouble. I got it running good and remembered what he said about the slow RPMs. I twisted the knurled wheel on the air vane a few clicks and its running like a top. I also
was given another v engine lawn boy that when I got it running it would rev way too fast and I adjusted it down by turning the little wheel the other way to get it running at a normal speed. I don't have a tach but Iv'e been mowing for about 50 years and I know about what the right speed sounds like. Any way my question is how does that control the engine speed? I'm guessing that turning the wheel a few clicks changes the tension on the spring but I still don't understand how that changes anything. I don't understand how that if the air vane is moved more forward, how does that increase the speed of the engine.
I don't know why it gets more gas by moving the air vane more. Could anyone explain how it works?
Thanks,
Jerry
