Small Engines (Lawn Mowers, etc.)/Poulon Pro PBV200 blower/vac


Recently had this unit checked out at local small engine repair shop. Technician said it had only 55lb compression and would cost more to fix than replace. Wondering what needs to be done and if there are instructional videos/instructions/youtube to direct? I've never done such engine repair but am a quick study! Unit has new plug and clean carb.

With that low of compression you either need a new ring, piston, cylinder or all the above.  If we were repairing for a customer we would replace all those parts.

If it were mine at home, I would just try a ring but knowing a new ring might not fix the problem.

If you decide to just replace the ring MARK which way the piston faces the exhaust.

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.
