Remove the spark plug and see if the flywheel will turn. If it does, then there is excess fuel in the combustion chamber--install the starter and pull it through vigorously several times to expel the raw fuel. If it does not turn, then suspect that the engine has seized due to insufficient or no oil premixed into the fuel. Remove the muffler and inspect the piston, ring(s), and cylinder for excess scoring. The repair is to replace these parts--an expensive process even if you perform the labor. Any existing warranty will not cover this problem. Hope this helps!

I ran over a rock with my craftman 650 lawn mower and it now makes a funny cranking noise when I try to start it I changed the fly wheel key and it still doesn't start.


When you try to start the engine pulling on the rope, is it easier or harder to pull to turn over the engine? If easier there is internal damage as below, if harder there is internal damage as below. That cranking or grinding sound could be the rope starter or the clutch of the rope start. So when you have the cover off of the flywheel pull on the rope and see if it makes the sound you are hearing and check the clutch that threaded onto the the crank holding the flywheel in place see that it turns in freely in the opposite direction of the engine running.

You may have bent the crank, take the spark plug out, put the mower on it's side with the carburetor on the up side and turn the mower blade by hand and see if you can tell if there is a wobble. While you have the spark plug out, look in the plug hole while turning over the engine to see of the piston is moving up and down. Another possible problem the cam gear could be broken and the valves not opening and closing in time with the crank.

Craftsman weedwacker 32cc how to get clutch off to replace pullcord


It is threaded onto the end of the crankshaft (with regular R-Hand threads). I spray some PB Blaster solvent on it, let it soak. and the whack it on the inside "ears" with a flat blade chisel or a piece of small hard wood. I know...you have to lock up the engine so the crank won't move...and you can. Here is the entire process.

Remove the tube that holds the flex-drive shaft from the front of the motor cover. Remove the throttle cable from the carburetor. Mark and unplug any wires for the on/off switch if possible. Now if you have pulled the driveshaft tube out of the way, the clutch drum is up next. Inside it, screwed into the very end of the engine's crankshaft is a Torx #25 screw. Before you loosen it, ou will have to lock up the engine. Remove the spark plug. Pull on the starter until the piston is down, then insert a length of clean, soft rope into the engine. The engine will come up and compress the rope, thus locking it in place to allow clutch drum and clutch removal. Loosen the T-2015 screw inside the drum.. It probably won't come completely out...it is made this way. Next, remove the clutch. It is screwed onto a small threaded section of the crankshaft Removal is counterclockwise.. It will be pretty tight. To help, apply peneterating oil. Whack the ears of the clutch near the center with a dull flat-blade chisel and hammer unless there are bolts. then use wrench. It will turn counterclockwise for removal and there will probably be a removal direction arrow on it's face. After getting that off, remove the Torx screws holding the cover to the engine. The starter unit should be mounted inside as it mates with the bottom of the flywheel to start the motor. Remember to preload tension (5-7 turns) on the starter unit. Make sure the handle is installed. Jam the unit with a screwdriver or something so you can insert and tie off the new rope. Then remove jam device and let recoil pull your new rope into place. Reassemble and you are done. Disassembly requires Torx head drivers ranging from T-15 to T-25.

Motor will not turn over. Checked air filter compartment to find 2 oz. of oil and filter soaked.


Not sure if you mean engine will not turn at all (locked) or engine will not start. The engine may have been on its side causing this condition. Clean carb and filter of excess oil. Remove spark plug and clean cylinder and plug of oil that may have entered causing locked condition. Replace oil lost from crankcase. With spark plug removed and kill swith on off, pull rope to blow out oil and verify that motor will now turn. If it still does not turn could be lock rod to crank or faulty pump. If engine had very little or no oil in crank and was run, suspect locked crank, however if your engine has oil senser, this condition would have prevented engine from starting. If you mean that engine will not start, low oil senser most likely preventing start due to low oil. Good luck

Pull starter rope will not retract


Disassembly and inspection/repair will be required. Here are the steps to take.
Remove the tube that holds the flex-drive shaft from the front of the motor cover.Remove the rear engine cover. Remove the throttle cable from the carburetor. Mark and unplug any wires for the on/off switch that go to the ignition coil (underneath front cover) if possible. Now if you have pulled the driveshaft tube out of the way, the clutch drum is up next. Inside it, screwed into the very end of the engine's crankshaft is a Torx #25 screw. Before you loosen it, you will have to lock up the engine. To do so, remove the spark plug. Pull on the starter until the piston is down, then insert a length of clean, soft rope into the engine. The engine will come up and compress the rope, thus locking it in place to allow clutch drum and clutch removal. Loosen the T-25 screw inside the drum.. You may be able to remove it with a long thin-blade screwdriver also.It probably won't come completely out...it is made this way. Next, remove the clutch. It is screwed onto a small threaded section of the crankshaft Removal is counterclockwise.. It will be pretty tight. To help, apply peneterating oil. Whack the ears of the clutch near the center with a dull flat-blade chisel and hammer unless there are bolts. then use wrench. It will turn counterclockwise for removal and there will probably be a removal direction arrow on it's face. After getting that off, remove the Torx screws holding the cover to the engine. The starter unit should be mounted inside as it mates with the top of the flywheel to start the motor. Remember to preload tension (5-7 turns) on the starter unit. Make sure the handle is installed. Jam the unit with a screwdriver or vise grips so you can insert and tie off the new rope. Then remove jam device and let recoil pull your new rope into place while holding the handle. Reassemble and you are done. Disassembly requires Torx head drivers or a good flat blade screwdriver for some models.

Your piston cylinder is partially full of oil and/or gas. Take the spark plug out and pull the rope four or five times to blow everything out of the cylinder. If it's still hard to pull over with the plug out check the oil level in the crank case to see if it filled with gas while the mower was on its side. Make sure the plug is dry and clean and reinstall it. When it starts it's going to smoke a lot until it cleans out the cylinder.

Chainsaw pull cord won't pull to start


Simply check to see if motor is locked is to remove spark plug and try to pull start. If motor turns, then he may have gotten gas in cylinder and created hydraulic lock. If moto does not turn, it is just a few screws more to take side cover off and see if rope caught in pully. In fact, you may want to take side cover off first, and make sure rope pulls out of housing, and self winds, like it should. At hat point, he can simple turn flywheel by hand to see if motor is locked up.

If the motor is locked up, you can put small amount of motor oil, (half a tea spoon) into spark plug hole, let it sit half an hour or so, and then try to work the flywheel back and forth to break it free. This condition may have been caused by running straight gas, not mixed. And, even if motor frees up, it may still need to go in for repair.

We have a couple of Poulin Pros at this saw mill where I work, and have had the piston lock up more than once, from guys dumping in straight gas. Sometimes we'ra able to free up piston, and make saw run again. And sometimes we end up tearing it down and repairing piston ring. Good Luck
