Try removing the spark plug and rotating the engine by hand.
It could be just a little corroded from shipment over the ocean.
But once you have it loosened up and the oil circulated, it should start much easier.
Make sure it has oil in it, because sometimes they drain the oil before shipping.
You could also have someone else try the starter rope. A new engine can be hard to start.

off you ask them they have it. ask maker of engine, the tool make would not. (sump) service manual is the name. ask maker https://www.briggsandstratton.com/na/en_us/support/manuals/results.html

This appears to be something for a Briggs and Stratton engine, so I moved it from the Microwave Ovens category. 'Make model (what is is)' in all questions please and in this case (what it is off) as well :>D Call Jack's Small engines.

Doesn't look like anyone came close to answering this question correctly.While I realise I am answering a VERY old post, a correct answer may help others that come here in the future who are experiencing the same problem.The issue is with the starter clutch. It screws onto the crankshaft and works like a ratchet wrench. It allows the crankshaft to turn freely one way but "catches" if turned the oher. Most people don't maintain them properly so it gets rusty inside and the bearings don't move like they are supposed to. Hence the clutch doesn't lock.It's usually a pretty simple fix. Remove the flywheel cover, secure the flywheel so it doesn't turn then use a rubber mallet and a drift to loosen the clutch. It has normal threads so it turns counter clockwise. It should come loose pretty easily. Once off, look at the front of the clutch. There is a cover which is just pressed on. You should be able to get it loose with a hammer and small flat head screwdriver. Carefull you don't loose the bearings (there are 6) which are pretty large. Clean the whole thing out, removing any rust and debris.Then spray the inside with some lite machine oil (don't use grease or any other thick lubricant).The shaft should have a piece of felt in the center of it. This should also be soaked with machine oil. To reassemble; place the washer and shaft back into the housing, then place a bearing in each "hole". Give it another shot of machine oil and press the cap back on.Put it back on the engine and replace the cover. You should now have a workng starter. There is a small hole in the front of the clutch. You should periodicaly squirt some oil into it to keep the clutch lubricated.

hi I think that the problem you have is not with the coil. let me explain : when there is the need to stop the engine simply we push a button or use a lever in both cases what it simply does the coil is grounded to earth this stops the spark supply to the spark plugs . find the cable which connect from the switch on to the coil because this cable intermits to short to earth stopping the spark going to the spark plug ( replace cable this will prevent the engine to stopping )

The engine is running too lean.

check for excessive oil in the sump the hose allows compression build up in the sump to escape to the air cleaner so the valve (????) is operational

If the engine is locked, it could be any one of several things. Most are rather expensive, like: seized due to no oil; broken rod; bad valve, etc. An engine mechanic is going to have to troubleshoot it for you.

What model number?

tank filter carburetor , sprayer , gaskets (sometimes) OIL-LEVEL to low or (it can happens but not often ) defect oil-control if oil level is good temporarily pull the oil monitoring loose bougie BCPR6ET does sometimes good equivalent services. If the ignition module is defect no sparking and you are order a new one you must know the serialnumber of the engine type to get the right one because of modifications by later build of the same models van later construction year. or there is a valve problem But that is rare . to high overcurrent for start start the generator without connected tools .

priming bulbs are normally held in place by a ring around the base with 2 or three screws remove that ring and the bulb comes out of the seat take it to a mower shop as most bulbs are the same if that is not the case ,take the carby to the mower shop and they will fit a new one for you
