Another "Boratified" blower.

Well no snow so I had to have something to do today. Came up with a little different approach. There were two things I wanted to be able to do when this mod. was finished. One was to be able to adjust the RPM at will. The other was to be able to get the bottom cover off without having to mess with any strings, wires, cables, etc. This is what the factory gov. setup looks like on a Toro CCR 2450 Here's what I came up with. I make an arm that I bolted to the handle. Drilled a hole in the end to hook the gov. spring into. I wanted to use the factory spring so the gov. could still function. Also I wanted to be able to return things to stock if I wanted to. This photo shows the arm and spring at what would be the factory position. This photos shows the arm and spring in the "lets blow some snow" position. The spring can be pulled 1" to 1 1/4" past the stock position. I revs up pretty good, but it doesn't have that scary "I'd better back it down" sound. You can see where I slotted the bottom cover so it can be lifted right off. Finished look. After I took this photo I went back and drilled a hole all the way through the handle. So I could use a bolt and self locking nut to hold the handle, to the handle. That set up allowed me to snug down the adjustment handle just enough so that it would move but stay in it's position. The first way I know would have rattled loose from the vibration. You push the handle to the right to increase the RPM. I had to bend the handle out from the handle like that. Other wise it hit the cover before you could run the RPM up enough. Where's the snow?

Nice job, jrtrebor! You do really nice work. Cut and bent sheetmetal that looks like it could be factory. Very cool. And thank you for taking the time to write it up and post it.
I think the string idea is really good, to let you control it as you operate. I think a way to rev the engine by simply squeezing the bail would be really cool. Anytime you're not blowing, the engine RPMs drop immediately. Squeeze the handle, and they climb. Ideally, the belt would start to engage before the RPM's start to rise, so the belt doesn't slip as much (engaging at 3600 should be easier on the belt than engaging at 5000). Haven't tried this yet on any of my stuff. With something like a turnbuckle adjuster, inline with the string, you could "fairly easily" adjust the tension on the string, so that your high-RPM setting will go higher or lower. Or, just pull the string more, of course, if you're doing it "by hand".

Nice job, thanks for posting. I am also interested in a variable rpm control. I'm still in the layout phase, taking my time: Power Clear 221QR Here is my idea for a control cable: http://www.hobby-lobby.com/pushrods_connectors_393_ctg.htm I need to study all the available components, a lot to learn since I'm not a RC guy (yet)
