Briggs and Stratton 5hp 130202 3166-01 Code 90102427
Hechinger by MTD Tiller Model 211-381-372/06-054290

Tiller was running fine a week ago, wouldn't start this week, and when starting to troubleshoot, noticed throttle cable was having no effect at carb, nothing moving. Have searched web high and low and found many diagrams and videos, but none that I can see match the set-up on this engine/tiller. The throttle cable is attached to the mechanism attached under the gas tank and their is action/it moves....spring is attached to same mechanism so that when at full throttle position, spring applies downward pressure to governor arm. Single linkage from governor arm up to carb is in place and intact, but there appears to be nothing to cause linkage to move upward to action the butterfly in the carb, only the spring holding downward pressure? I'm thinking something is missing/broke/gone, but don't know what. Best picture I could get of current state is attached. Any help is appreciated.

First of all you need to find that oil leak. Second you need to clean that area shown in your picture so you can see what you have. After that read over section 4 of this manual to identify which governor control system you have. Then you will be able to see how everything is supposed to work and if you are missing an parts. Post back with your findings.

Understood and thank you for responding. The manual (Section 4) that you reference in your post...I am not seeing a link or file to access. Could you please point me to that reference?
Thank you for your time.

The govenor spring attaches to the govenor arm that attaches to the rod going up to the belcrank to the butterfly. The govenor gear inside the engine applies pressure to the govenor arm against the spring tension. When you start the engine at idle the govenor will overcome the spring tension and pull the butterfly to the idle position. Your linkage is probably fine.

Like Rivets said, that thing is filthy. What does the air filter look like? Oil?

Looks like a typical old tiller with a 5hp briggs. Used hard and oil not changed often enough then the 2 little drainback holes in the breather clog up and it starts blowing oil out of the breather all over the engine. Put gas in it and just add oil when it gets low and don't ever clean it. ?
Put a new spark plug in and see if it starts.

Thanks again to those who offered assistance. With the help of the attached manual, the linkage was identified as being very close to this setup with remote control as shown similar to the inset diagram:


With the diagram, and a bit more degreaser, I was able to confirm that all parts were intact, and functioning as should. Also having gained some understanding of the governor gear and associated parts, things made more sense. So, I was on a wild goose chase. Nothing was missing from the linkage, as Hammermechanic Man suggested. The actual problem ended up being a stuck valve, as diagnosed and corrected by my jack-of-all trades neighbor.
Yes, I have acquired a new air filter, will get a new plug and gap it appropriately. I change the oil every year, but the air filter seems to have missed a few maintenance cycles. After some research, I see that I need to take care of this one, because it seems they don't make tillers as heavy duty as this anymore.
Now, where are these "2 little drainback holes in the breather" that I need to be sure are free and clear?

If the oil is all over berween the crankcase and the gas tank it is a sign the oil breather is clogged. The cover on the side of the engine that gives access to the valves is the breather. You have to take off the gas tank to get to it. Not fun on that engine. If the engine has a lot of ring blowby it can cause the problem too.

Look at the gasket. There are two small slots that line up with the two small holes in the breather. If the holes plug or the gasket is installed upside down the oil can't drain back properly andbit will blow oil out of the breather hose.

Or someone dumped oil all over the engine when filling. Could be several things with oil all over it.

I think that clean and dry is the answer, I would be shot by my dad if I had a machine in that condition.
