sounds like low voltage and the starter solenoid is chattering

Toro published 3150 as the ideal rpm on my 21" recycler #20055. The industry spec of 3000 - 3400 rpm is based on 19000 feet per minute at the blade tip. Trying to set it by ear does not work unless you do it every day. You can get a free app for your phone that will give rpm or use one of...

by a borescope on Amazon and take a look inside the cylinder to see if it is rusty. That is where I might start. Next I would pull the starter assembly off and the spark plug out, then see if it spins freely with that. If it has electric start, also make sure the starter is not hung. Make sure...

It takes 3 things for a gasoline engine to run, air/fuel, spark, and compression. You will need to monitor the engine to see what is missing. Also make sure both cylinders are running when it is running. Sometimes when an engine is down on power it can be killed by load.

we are in the Looney state. Here they banned any new hydrocarbon engine that is under 25 HP. As a result, there are a plethora of backyarders running around snatching up every thing used for sale, cleaning it, and then flipping it. The only things not selling are the small tractors and older...

voltage has to be DC and it needs to be around 13V - 14V. If the charging circuit isn't putting that out, gotta figure out why.

not familiar with the model. That said, some mowers develop a belt and pulley geometry issue as the brake pad wears. Check the pulley brake pads on yours if it has them to be sure that the geometry is not changing due to pad wear - causing sensor problems.

take it to the dealer before you lose or cancel out your warranty. In the meantime loosen the gas cap just a little and see if that changes things. If you can see the fuel drain inside the tank with a flashlight (please don't drop it), see if there is loose grass or something blocking the pickup...

Check the valve guides

is the bushing oilite or plastic? If it is oilite the proper way to install it is hold you thumb or hand over one side, fill it with oil and then squeeze the center until pressure pushes oil thru the bearing. That will impregnate it with oil for its life. If it is plastic that doesn't work...

45 is awfully low. If it doesn't come up, even if you get it going what will the power be? Like that is about a 4:1 compression ratio. (45psi + 14.7) \ 14.7= 4.06. Many of these mowers are like 100 - 120 psi without a compression release. (120 + 14.7) \ 14.7 = 9.2:1 or about double what you have.

yeah right. Had a CJ7 that loved to build up carbon. One night while the manifold was off I took some chunks of carbon and put them in every solvent I had. MMO - no softening after 2 weeks Acetone - no softening after 2 weeks Water - no softening after 2 weeks Carb cleaner well known brand -...

Are you saying that even the starter does not turn over? Might want to get the volt meter out, check the battery voltage while turning the key. Then check it again between ground and the starter. Your incline problem can be a bad fuel pump or vacuum hose to it if you have a vacuum pulse type...

you need to pit down enough that someone can answer your question. need the actual engine number and serial In general there are many reasons it pops in the exhaust. It can be anything from an adjacent cylinder not firing, a misfire on one cylinder that sends a mixture of gas and air into...

??????? Maybe with a transparent tube.

unless you can find a core engine locally that runs or can be rebuilt, that engine is way more costly to rebuild than buying a new one, unless you are in a state like California where they cannot sell new engines due to state laws. Electric only new under 25 hp. Specifically by the time you...
