Small Engines (Lawn Mowers, etc.)/Replacement Engine for B&S 130202 3010


I have a very old Lazy Boy 5 front tine garden tiller made by Parmi. It was handed down to me from my dad after several years of gardening and I have used it for the last 20 years myself. The engine has been maintained and servised regulary. But the time has come to replace the engine and I was hoping that you could help. The tiller has a Briggs and Stratton 5HP horizontal shaft, Model 130202 Type 3010 01. I'm sure there not a direct replacement, but if you could maybe direct me to a model that would work. Thanks in advance

ANSWER: Do you know if the engine has a gear redution on it.  The gear reduction will be an external part bolted on the rear of the engine, opposite the starter side.  

The link below is a good source for engine.

You will need to measure the diameter and lenght of the shaft then just match an engine.  You can send me the measurements and I can help narrow down your options.

QUESTION: There is a 2" dia gear on the shaft for the belt. The shaft is 2 1/4"'s long and 3/4" dia.

Many of these engines will fit.  Now all you need to do is verify your gear/pulley will work.  most likely the gear is held in place with a set screw and a square key.  Most of the engine have the keyway you need.

Tiller engines experience more wear than almost any other engine because of the dusty operating conditions.  I would probably look for a cheaper Briggs engine with a decent air filter.  When the engine wears out I would just replace it again as they are pretty cheap compared to today's repair shop labor prices.  A tune-up usually runs $65-85.  Two or three tune-ups and you could just replace the whole engine.

Make sure you can remove the pulley before you buy an engine.  Those pulleys can sometimes be real tough to remove.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
