Hello John, Thank you for the question. Sadly, I could not find the parts requested. I recommend contacting the manufacturer and seeing if they could provide you with a part number, and then you are always welcome to check back to see if we carry the part. Hope this helps!
just rebuilt this unit from the block out (carb replaced last year) Replaced the plug wire. It starts but will die at idle but it will accelerate and run as long as you don't let it idle. I use a 90 oct premixed gas mix from home depot
Richard Ballard for model number RY0842A asked on 2019-11-14
Hi Greg, this could be caused by a variety of issues. 1.Airflow Issues, check the air filter to ensure that it's not clogged with dirt and debris. 2.Spark Plug Problems, Another problem that can cause revving and dying of a lawnmower engine is a faulty or poorly adjusted spark plug. 3.Carburetor Adjustment,A carburetor that's incorrectly adjusted is a common cause of poor engine idling that results in hunting and surging. 4.Fuel Problems, If the fuel has been left in the mower while it was stored over the winter or while the mower has remained unused, drain it and replace it with fresh fuel. Thank you for your question and good luck with your repair!
