A 21hp Briggs & Stratton engine may smoke due to several reasons, including oil overfilling, worn piston rings, or a damaged valve seal, which can allow oil to enter the combustion chamber. Additionally, using the wrong type of oil or running the engine at an improper temperature can contribute to smoking. If the air filter is dirty or the fuel mixture is incorrect, it can also lead to excessive smoke. Regular maintenance and proper oil levels can help prevent these issues.
A good quality 30wt is Briggs recommendation

if it has one, it will be simple to remove the bolts and pull it off. if it doesnt, then you have to pull off one side of the crankcase.
Yes, the push rods on a 21hp Briggs & Stratton mower can differ based on the specific engine model and configuration. Variations can include differences in length, material, and design to accommodate different engine specifications or performance requirements. It's essential to consult the engine's service manual or parts catalog for the correct push rod specifications for your specific model.
If it an opposed twin, then an RJ19LM. If it is a V-Twin, then an RC12YC. Either gapped at 0.028 - 0.030"
A 21 hp Briggs & Stratton engine typically holds about 1.5 quarts (or approximately 1.4 liters) of oil. It's important to check the owner's manual for the specific model, as oil capacity can vary slightly based on the engine design. Always ensure to use the recommended oil type for optimal performance and longevity.
there should be a screw in the side of the carbuerator. turn the screw all the way in be careful not to bottom it out tight you will ruin the needle valve. then turn the screw opposite 1 1/4 times this should be good slow idle and also fast idle speed.
Also does anyone have any reviews for comments on the Ferris zero turn mowers, i am looking at the IS500Z 21hp with 48" cut.
10W30 is always a good one. SAE 30W oil is recommended for use in weather above 40 degrees Fahrenheit. Below 40 degrees, you can use a multi-weight such as 10W30. You can also use synthetic multi-weight oil year round, but it must be changed as often as indicated in your owners manual, which is 50 hours (25 hours if used in extreme conditions) or once a season.
They are very similar engines. Someone that has had an issue with a B&S in the past will tell you to get the Kohler. Someone that has had issues with a Kohler in the past will tell you to get the B&S. On paper, it looks like the B&S offers a tad more torque, so that's an added bonus. I'd go with the B&S personally. When I think of Kohler, I think of toilets and shower heads. When I think of B&S, I think of small engines. However at least the 21Hp that is used on the husqvarna has a serious problem with the carb....has a solenoid on the bottom of the fuel bowl that gets hot and boils the fuel when you turn it off. Causes clogged jets.
I think they are about 21hp with a race exhaust on. They do aprrox 65-70mph i believe, which doesnt sound extremely quick but they are designed to accelerate rapidl instead of having high top speeds due to the nature of motocross. I would like to see a 0-40 time for a cr85 as I think that would be more intresting.
Converting rated Watts to HP 17520watts = 23.5hp Converting surge Watts to HP 26250watts = 35.2hp Selecting midpoint 23.5hp + 5.85hp = 29.5hp As such, it’s probably 30hp give or take. A Northern Tool data sheet specs the BP17500E out at 30hp. Search for it. This post doesn’t permit links.
