Honda HR214 Manuals, HR194 Manuals, GXV-120 Manuals

So while the machine shop is doing unspeakable things to the honda gxv120, I'm getting my stuff in order so I can start putting the pieces back together when I get the block back.

3800 rpm Honda gxv120!

So after posting my "before" tear-down  video of the smokey hr214 mower, some of the guys over at "My Tractor Forum" said that Yoshimi was running a bit fast...like a thousand rpm fast! Whoops. So I ran out to Northern Tool and picked up a digital tachometer like this one and hooked it up. After a little  learning curve, this tach was pretty easy to set up; red wire gets wrapped around the spark plug lead, and the white lead gets grounded to the frame. The hr214 sparks every revolution (even during the exhaust stroke), so i left the stock settings in place, but you can also set it for different types of motors (distributor vs. non, etc).

So what did I find? Holy crap, this thing was about to fly apart! The specs for the gxv120 call for about 2,000rpm at idle with the blade disengaged, and I was up around 3200 at idle, and around 3700 at top speed.

Hmmm...after reading the manual, it looks like the idle gets adjusted at the carburetor via the throttle stop screw, but no dice! Long story short...the breather hose was actually broken off a the block  and had pressed the governor arm as far as it would go-keeping the engine running at top speed. After seeing the breather hose venting to the outside world, I decided to go straight to the tear-down, and spent most of today taking the gxv120 apart. Video of my rev-happy Honda below:

This post is for Vocegrande! He's missing a breather hose off his hr214, so here are some pictures that might help him find a replacement. It looks like a regular fuel hose from the auto parts store would do a pretty good job of replacing it...but if your engine blows up, don't blame me ;)

Let us know how the new coil works out Vocegrande!

Honda hr214 parts arrive!

The piston rings, blade, head gasket and tires all arrived today. I got the parts from plano power, and am happy with the cost and speed of delivery, but they included a wrong knob! So I'm waiting to see what they'll do. In the meantime, I got the tires put on; what a hassle! You wouldn't think that two bits of rubber would need a half an hour to install, but it took all of that and some sweat. Here is the offender:

Pro-tip: Use two screw-drivers like tire-irons to slowly pull the rubber over the plastic. Whew!
