Question about Craftsman Push Rear Bag Lawn Mower w High Wheel (CA)
I have a Sears Craftsman 6.5 HP mower. It's about 4 years old. It has become more and more difficult to start, and today a big problem. After getting it to start after priming and pulling a few times, it started to "knock" after about a minute, then shut down. I got it started again, but the knocking continued and it shut down after a few seconds. It's not a blade problem. Then, when I tried again to start it, I heard a loud "pop" and smoke came out of the side (muffler?). I tried again, and it popped again, Then, I tried to start it on an off for the next couple of hours....nothing! There's gas, oil, it's clean underneath.......I don't know what the problem is. Can you help ?

Sounds like you have water / debris in your carb fuel bowl. Using spray carb cleaner will only work if you remove the bowl and clean the carb jets. Also, you could have water in the gas tank as well. First, remove your air filter, then remove the 3 screws that attach your filter bracket to your carburator and mower. Take off your fuel line at the carb and drain all your gas into a clear jar. If it looks very yellow, cloudy, or see water in the bottom of the jug, change your gas. Using a half inch socket wrench, after gas line is disconnected, remove the fuel bowl and clean with carb cleaner. Also, examine the bolt you just removed. There are 2 jets in the side and one at the end. Using the carb cleaner, make sure they are clean as well. Use the carb cleaner extension tube to spray up inside the bottom center of the carb, where the bolt threads, to clean that area as well. After all this make sure your float assembly is intact and reassemblt the bowl to the carb and reattach the the fuel line. finish by reattaching the air filter support bracket making sure the gasket between the carb and the bracket isn't damaged. Also, never use last year gas, alway buy freah every year.

I think that this is a 4stroke engine and runs on neat petrol.Have you been putting oil in with the petrol like a 2 stroke engine needs because this would account for the smoking.If not the check that you havn't overfilled the gearbox oil.

Do you meanengine mounting bolts, blade boss, and 'Operator Presence Control' cable? If so, they are generic parts - not specific to your mower. I have no idea why you are having problems ordering them - they are consumable parts, and should be stock items for ant garden machinery repair outlet.

On many Tecumseh engines, there is a crankcase breather located under the flywheel. It has a cork gasket to seal the top plate of the breather. Either the rubber breather housing is cracked, or the cork gasket needs replaced.
