Hi i have a jd z445 zero turn that i just purchased it sprung an oil leak and is smoking. it has the27hp briggs and stratton engine . what would be the most common problem????

SOURCE: 31p777 18.5 hp briggs & stratton valve cover leak

Both can cause problems. It is recommend that you do not go on a grade more the 10% for your safety and the safety for others around. But if the valve cover is leaking this can lead to major problems if not repaired on a timely matter

SOURCE: Briggs & Stratton 4.5 hp running rough...too much fuel

Hi did you squeze excess oil from filter so it can **** air in??

SOURCE: Briggs and Stratton 22hp v twin OHV smoking badly

First thing to do is pull your dipstick and check for broken or missing O-ring also as you pull it, look to make certain that it was seated properly and all the way locked. If either condition exists, you will be leaking into the crankcase which will cause your symptoms

SOURCE: Briggs & Stratton Briggs Stratton Intek V -

these are common for doing this ,if you dont want to pull it down and hone the cyl. then i would use a heavier oil say 20w/50and that will probabley solve your problem

Hi and welcome to FixYa, I am Kelly.
When a primer bulb is slow to return to a static conditon there is a restriction in the fuel supply. Since this carb is mounted directly on top of the fuel tank the troubleshooting for this involves removing the gas tank and carb as an assembly from the engine. Remove the end bolt and then the side bolt spacer that is just above the tank. Be careful or the spacer will drop. Pull out on the tank until it slides off of the intake. When the tank is free of the engine tile the bottom of the tank toward you and disconnect the throttle linkage. NOTE the hole the linkage is connected to! Set the tank on a flat surface and remove the carb mounting screws. STOP! Do not lift the carb off of the tank until your sure that the gasket and diaphragm are not stuck to both mounting surfaces. You may have to carefuly slide a thin knife blade FLAT across the top of the tank to free the carb from the tank. There will be a SPRING on the bottom of the cabr also. Do not lose this spring and ensure you see how it is installed! Once the carb is free of the tank clean the screen under the carb and the carb with carb cleaner. Reassemble carb to tank. Fill tank with gas and re-check primer bulb BEFORE you reinstall the tank and carb on the engine. If it still does not work.. properly you need to clean the passages again. Worst case you remove the primber bulb to see if there is debris inside the bulb plunger area. Installing tank and carb to engine....
Tip the bottom of the tank toward you.. connect the throttle linkage, watch the o-ring that is in the carb intake sealing area and make sure it seals. Install side bolt and then the end bolt.

Just back tracking here.. I have determined this is most likely a 11A-B04E000 Yard machine with a 5.0 Hp engine... ( Briggs and Stratton refers to this engine as the 10T500 series.
