It looks like the number you are giving are from the mower deck, and would work great for anything but the engine. On a flat head engine above the spark plug on the tin air shroud there will be some more number and they go to the Briggs and stratton engine you have.On a overhead valve engine you should look on the valve cover. There will be model, serial , and spec numbers, all three would be great and would make it easy to look up the primer bulb and post a link to it for you.

you will need the model and type numbers from your engine to find the correct clearance numbers

go to MTD web site for info .

There is no way to get the diagram without knowing the model number. The model number will be under the seat most likely.

sounds like it broke a ring to fix better to buy new moter not worth trying to fix

I am pretty sure this is a 4.5 Hp engine with the carb on top of the tank. Plastic carb 4 or 5 mounting screws mating carb to tank. Remove the air cleaner... and tighten the carb to fuel tank mating screws. It is drawing air between the tank and the carb. This should stop the surging. If is has been a long period that you used the mower with the surging problem the diaphragm between the tank and the carb may be either out of position or damaged. The diaphragm is not expensive. Usually the first time this symptom presents itself you can resolve it by tightening the carb to tank scresw. IF you have the primer bulb carb..mash the rubber of the bulb against the carb body. If the surging stops... the primber bulb has a pin hole in it.

You passed the mower model number and not the engine model number. When we use the 11A number you passed all we get is the base and handle parts. If you need more help I need the model number off the engine just above the spark plug wire on the air shroud.

Thanks for choosing Fixya,
