Honda GX200 Govenor Adjustment

[wobbedennis]

I have a GX200 from Honda that my AUTO shop teacher gave me. It runs fine, but immediantly runs away, the govenor dose not seem to work at all. It was not compleat, I had to take the carb, govenor linkages, and most of the springs off of a GX 160, but it also is from Honda. There is little to no tension that should cause the govenor to fail and stick like it has. It is on an old Go-kart that my uncle gave me. I'm stuck. I have tried adjusting it in both directions, but nothing has worked. Also, I don't know if this is related to my issue, but the cylender was baddly rusted so the engine would not turn over at all. I got it to turn over and the rust has been removed.

Static Governor Adjustment:

Does not matter what type of engine, if it has an internal governor the static adjustment is the same on all of them.

Locate the governor shaft where it comes out of the engine block. Loosen the arm that is attached to the shaft. Hold the throttle on the carburetor to the wide open position and note which direction the arm attached to the governor shaft moves. While holding the throttle wide open rotate the governor shaft in the same direction it would turn to open the throttle, turn it until it stops. Tighten the arm back down to the governor shaft. Thats the procedure for making the static adjustment on any internal governor, horizontal or vertical.

If after following the above procedure the engine still runs away, then the governor assembly inside the engine may need work. The rust on the cylinder would not have caused the over speeding issue.

does it run right just operating the throttle? If so, on a go-cart, I would just by-pass the governor.

Norm, no It's fast enough as it is, it dosen't need to do 70 or 80 mph, And to the static adjustment, I did that. When that didn't work, I did it in the other direction. When I operate the throtle manualy, it dose run fine, really good acctually. What could go wrong with the shaft that sticks out of the block?

The fkyweight mechanism inside the block which operates the governor shaft is probably blown.

DUH!!! . . Who said you had to run it at wide open throttle ? People don't normally run cars and motorcycles at full throttle.

or on the go-kart it most likely was purposely disconnected INSIDE the block during a previous overhaul, etc!

Look at these two links especially the second one and it will give you an idea of governor operation, when normal. The first link is the Perr Home page Notebook link for other selectable GOOD basic info!
You will have to find a exploded view of your Honda engine for your exact governor set-up inside!

Thta was what I was begining to think. If the weights or the slide are stuck, then that would give me my issues, or worse case senario, the gear is stripped. Otherwise, I do understand basic engine operation, even if I can't spell.

It's a bit hard to imagine the Honda governor being no good.


You could do a test by doing this;
Disconnect the governor from the throttle. (leaving the arm attached to the gov' shaft).
Add a little spring pressure to it, (pulling inthe same direction to close the throttle)

Start the engine and throttle up and down manually. The governor shaft should react accordinally. If it doesn't, you'll need to crack the engine open.

If it does, I'd play around with spring tensions to pull the governor closed (which actually sets the throttle opening). So far, not much has been mentioned about springs. (or which hole the link is in the gov'ners arm)

That is inginious!. But I have tested the springs, it is not them. I ran it with out them and made it idle manualy. It remained closed, but I had to make it closed. I found the issue. The slide that the wieghts control, was missing. once that was replaced, it runs fine now.
