Just a quick note to say that everything went just great. I was 97% positive that it was installed correctly, but that could be a humdinger of an error and this being my first time and all...
The key I think for me is when I removed the old valve, I kind of messed it up, but that ended up saving me. It was real stuck in the tight space and I turned it the worng direction. Anyway, when I was trying to wiggle it out, the L pushed a lever all the way to the front, and so I could feel that through the valve. So when I installed the new one, I already knew what it would feel like to push that governor all the way to full throttle. When I put the new one in, I made sure it was hoked on properly by pulling it out and making sure it pulled the bar with it. I did this about 10 times, because it couold come unhooked if you wiggle a little when pushing it straight in. By pushing in and then pulling out to see if it was still hooked, I was able to install it properly and be positive by the 10th in and out and back in. It only came unhooked 1 time in there and I had to wiggle the thing in a certain way. Anyway, that info is for the next person who has to do this task. Very easy, but make damn sure!
Remember the #1 rule of wrenching, if you are getting a bit frustrated, walk away! Come back when you head is clear and you are calm. That will save you everytime!
The bolts are 10mm, and I used a combo wrench and a small rachet. Also, the bolts are 10mm for the air housing assembly. THe only special tool needed may be the little hex nut on the plastic throttle assembly which you must remove to access the valve. All in all a good job, but you can bet I had my 17mm wrnech in hand and a piece of wood for the hole when started!
