  • GREAT LITTLE MOTOR @ REASONABLE PRICE
Used this to replace a briggs&Stratton 550 140cc engine. On a troy built push mower EVERYTHING WAS DIRECT BOLT ON. Reused motor mount bolts,shaft bolt and plate along with blade mount. Only thing that needed done was i tapped the bolt holes for the engine. My test run was in the rain cutting 2.5" wet grass, Engine didnt even try to die. Obviously the bischarge got clogged but acted like a mulch plug. ... show more

  • Cheap solution
Has an unusual bolt pattern, but starts easy and runs pretty good. It's a cheap price and I'm going on my second summer using it as backup mower.

  • Perfect fit
Bolted right in place of the Honda engine. Now just waiting for the blade adapter.

  • UPDATE TO PRIOR NOT SO GREAT AFTER 6 MONTHS WITH LITTLE USE.- NOT VERY PLEASED !
UPDATE TO MY PRIOR REVIEW FROM 2 STAR TO 5 STAR - The Seller contacted me and his engineer's determined the problem with the motor sent to me. They found the solution and have sent me the proper fix for the concerns. I am pleased with the Seller's Overnight response and solutions. My rating is now a 5 STAR ! THANK YOU SELLER. This Motor looks great. No complaints about packaging, arrival time, instructions, noise is typical, etc. But, the motor runs irregular, fast slow, fast slow, takes 5 to 10 minutes for it to calm down, but still does not run at a steady RPM. I used it once on a mower and it had good power to easily cut. After 30 minutes of use, and upon restart later. When pulling the start cable 3 times, it blew off the air cleaner cover, braking the hinge mounts and clip mounts that keep the plastic filter cover on the carburetor. The bang was loud and was not expected. I never had a motor do this before. UPDATE: I sent email to the Seller requesting replacement air cleaner cover. NO REPLY NOW TWO DAYS WAITING ! UPDATE 4-14-2026: THIS ENGINE IS 6 MONTHS OLD, THE RECOIL STARTER COIL AND PAWS ASSEMBLY BROKE. IT IS STILL UNDER THE 1 YEAR WARRANTEE. WROTE TO THE SELLER AND WAITING FOR A REPLY REGARDING WARRANTEE COVERAGE. INITIALLY THE SELLER TOLD ME TO GO TO A REPAIR SHOP OR REPLACE THE ENGINE WITH A NEW ENGINE, DUE THE HIGH PART COSTS. AND NOT REPAIR IT. WOW ! WAITING TO SEE IF UNDER WARRANTEE ? ... show more

  • None serviceable.
It's not a serviceable engine. No oil drain, which means it won't last long.
