The engine on this Honda HHR216 mower (3HNXS.1871AK) does not run smoothly, it surges. I can see the governor linkage moving in time with the surging and if I grab the governer link and hold it steady then the engine smooths out. Why might the gov be doing this and how do I correct it?

Surging is a common Honda issue and it commonly occurs because the carburetor idle jet is blocked. Cleaning the jet usually fixes the issue, I say usually because sometimes the whole carburetor will need to be removed, stripped, and cleaned.
If the spring is set in the wrong position it can cause the engine RPMs to surge. Over time the spring can stretch out, causing the same engine surging. Often surging caused by the governor can be fixed by simply adjusting the governor spring. It usually only takes a small adjustment to correct the surging.
The mower surges when the carburetor sucks air through an unsealed gap in the air intake manifold instead of through the air filter. Dirty carburetor. Clogged fuel jets inside the carburetor commonly cause the lawn mower engine to surge. Clogged jets can`t provide the right mix of air and fuel to the engine.
The problem may involve an annoying change (up/down) of engine speed while cruising at a steady pace, a low drop (or even cut-out) at idle or when approaching a stop, a wild high engine speed of several thousand rpm followed by a drop to near zero, etc.
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
Engine surging is usually a warning sign that your car or truck is having combustion problems. Since a vehicle`s ignition wires and spark plugs play a major role in proper engine performance, it is likely time to check your engine`s electrical components.

The RPM’s are to high and I can’t not turn them down. I tried to adjust them by turning the adjustment bolts. NO LUCK
You need to adjust the governor spring. Did you recently do some work on it? If so, you must have got that particular spring on wrong. What hp is your motor?Jim
Racing of a Honda 160 CC lawn mower engine
When a small engine “surges” in all speed ranges the possible causes are:
*Dirty air filter
*Water or contamination in the fuel system.
*Breaks in the spark plug wire (leaking), loose or corroded terminal connections causing an intermittent failure.
*Misadjusted or malfunctioning governor.
Problems with surging only when under load or at idle are likely caused by carb blockage or misadjustment.
Hope this helped and good luck to ya!

The engine surges at idle and then does not run constantly underpressure. sounds like fuel but cleaned all lines and used new fuel. any suggestions
A new spark plug and don,t forget to push in the choke after start.
Honda HRR216 does not start at all ,what could be the problem
Check to make sure you are getting fire/spark at the plug, if so then do the following:Check/Clean/Replace your fuel filter if you have one.If the mower/weedeater/edger is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.Be sure to use compressed air to blow out all the fuel and air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instrucitons you get with the carburetor kit.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.

Good question first you need to find top dead center.if you cant find any marking on cam shaft remove spark plug. place thumb over hole and gentle pull motor over first will be suction next you will feel compression agaist your thumb this will be the power stroke as you pull motor over note when you first feel this and when this stops .this will give you a ball park idea of TDC.align the ignition system to fire here
