Briggs & Stratton 21hp TWIN Engine Swap on Racing Mower 

If anybody knows the displacement size of this engine then lmk! Or if I can get billet upgrade parts for either one of these engines!

I love those opposed twins. Such a unique engine!

I have one of these on an 82' snapper. Was made in 01😄 great engines

Go bulldogs! love the shirt !!

I have an old rider and I want to engine swap it but on the old engine there is two wires coming from the solenoid to the engine but on the new engine there is three, what do it do?

Amazing genius many will believe in Comparison. Just a musician here trying to build Craftsmen and John Deer x400 plows and cabs home made. if I only had your Brain Strength🦾.🤔🧐😆👍

What kind of engine did it use to have

You always film yourself looking in to the camera while driving? You should be watching the road, your monologue can wait.

Mine has a 18 horse twin, and they are very reliable. You just need ear muffs, ear plugs, or a helmet. The governor bypass won’t hurt it, mine knocks and won’t blow even bypassing the governor

I just did almost the same swap, a rusty LT1000 with a good 21hp twin and a solid LT1000 with a blown 17hp single. You don't just swap the motor, you have to also swap the rear fuel tank, from battery tray, fuel line, battery cables, come cable, and throttle cable from the 21hp engine. The carb is in a different location, which is why it's easiest to keep the cables with their engine, and the 21hp engine will hit the tiny fuel tank, making it best to bring the huge rear fuel tank and hose with the engine. The twin muffler was junk, I had to get a new one off Amazon. Taking the body off for the tank swap was easy, 6 bolts and twist the shift knob off.

Think of it in cc though. He slapped a 700cc monster onto that thing. Mines a 19 hp.

Have you ever thought of flipping the trans so you don't have to run a jackshaft?

Man your channel is so underrated. Keep up the work dude looking forward to the next video

Does hooking the throttle cable directly to the throttle arm on the carb Bypass the governor? On my stock twin engine, its hooked up to this little plate underneath the carb

Hi! I need an advice since I got an opposite 18hp and I can't remember how I should assembly back the intake valve, the order of oil stem spring and retainer. Plus I need to know how bad can be that I made a govenor delete, since I can't assembly it back cause the thread for the pin(retainer) is shredded so needs I fresh thread to keep the governor assembly. Thank you in advance.

It would be cool if you put a 212 on a mower. Nice video!

I was given a Briggs & Stratton push lawn mower but the cord seems really hard to pull, ideas?

Very cool bro
