Take all the shrouds off remove the head bolt remove the head gasket clean off the dirt then reverse the process. Hope this helps
The most common place for oil leaks is the sump/crankcase cover gasket. A torn gasket will allow oil to escape. A common cause could be a blown head gasket putting too much pressure in the crankcase.
No alignment is necessary on governor gear, only the camshaft (timing) gear.
Check the gasket between the air filter backing plate and the carburetor. Usually if that is sucking air then the primer won't work. Your best bet would be to just replace the gasket and possibly the primer bulb as well
Change the gasket under the carb. The part cost about $5 and will take you about 30 minutes to change.
White smoke is eaither a blown head gasket or you have water in the fuel system. This is not to be confused with flooding an engine and seeing white vapor coming out of the exaust in which that would NOT be smoke, it would be gas vapor's. If your burning oil, the smoke will be blue and smells of burnt oil.
Well first of all, what size or brand of engine? If it is a lawn mower engine, it deals with incorrect crankcase pressure from most likely a head gasket failure and/or breather problem. Briggs & Stratton engines thru the 90's are very known for this on the rider mower engine.
put the crankcase together with no gasket and move the crankshaft. the amount of movement you get will determine the gasket thickness. if it is a lot of play then use the thick gasket, if there is little to no play use the thinner one and if the movement is in between use the middle thickness gasket. not a super technical answer but it should help you out
There are several reasons the engine would backfire, but the three main culprits are a dirty air filter, a loose intake manifold bolt or gasket (vacuum leak), or a faulty spark plug. If the problem is not one of these three, check out a book on small engine trouble-shooting and repairs from your local library. You will find other procedures a little more complicated in the manual to help you trouble-shoot.
You must first split the case after draining the oil of course then pull the cam out being careful of your lifters not to fall out if they do just put them back in . . . now when you go to put the new cam in there is a dot on the camshaft and the crankshaft that has to be lined up in order for you engine to be in time. Make sure to line those up when you put the new cam in and you will most likely have to replace the crankcase gasket before putting it back together unless you managed not to rip the gasket when you split the case. After you put it back together put oil back in it normally around 1 quart and then you are good to go.
One of the causes is reduced airflow to the carburetter, so cleaning or replacing the air filter may help. That may help but that will not cure the problem. If the lawn mower is surging then it is getting enough gas then it is being shorted. If the airfilter was the issue, the engine would more likely just run at a slower speed(2500-2800rpm's). Since the engine is surging, the carb must be cleaned and the gasket between the carb and gas tank has to be replaced. This is a very common issue for the Briggs 3.5 to 4.75 vertical shaft engines. It is very simple to clean the carb that is on that engine. Simply remove the airfilter and the two bolts holding the carb/gas tank onto the engine. After it you have the carb/gas tank in your hands, take the 6 bolts out that connect the carb to the gas tank. Clean everything out and replace the gasket and you are good to go. The most important thing to remember when you are removing the carb from the gastank is to take note of what goes first onto the gas tank(the gasket or the diaphragm, some come with the gasket first and some are the diaphragm first...luck of the draw. Hope that helps!
