Small Engines (Lawn Mowers, etc.)/Carb


Hi Eric
I have a fairly new (5 years?) WeedEater lawn mower I bought from Sears, with a Briggs and Stratton motor. Sorry I dont know the exact make and model. I keep it clean, change the oil and spark plug once a year, but this year the engine started revving a bit. I checked and the spring and wire on the carb were stretched and bent. I took it to a shop and they said I needed a whole new carb because it was 'one of those cheap plastic ones'. I dont mind the expense, but I feel it is too new to have to make a major repair. I remember my Dad's old LawnBoy lasting forever! Thanks for your thoughts and have a great summer!

Depending on the engine model it may be cheaper to just replace the carb.  Some parts in the plastic carbs can not be replaced.  The combination of plastic carbs and ethanol fuels is not a good situation.  Each year, over the past several years, we have replaced a lot of carbs and it is getting to the point that it will more common to replace rather than repair due to carb designs and cost. Can you attach a picture or your engine

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.
