Subject: Carburetor repair/cleaning
Question: Hi.
I am trying to get a Murray riding mower running again. I have replaced the fuel line, spark plug, ignition switch, battery, etc. I have the engine running, but only in the choke position. As soon as I move the throttle switch it dies. I went to the local lawn mower repair shop, they gave me a carburetor kit and suggested I clean the carb out thouroughly. I have done all of that. The only problem I encountered was I could not get the inner screw out of the carb once I had the bowl and float removed. I left it in and replaced the other parts. I sprayed the carb well with carb cleaner, reattached it to the mower and experienced the same problem. Any ideas?
Thank you greatly.
Answer:
Hi Davina,
You are on the right track. An engine that only runs with the choke on, indicates a lack of fuel flow to the engine. The most common cause is dirt, debris or gummed fuel in the carb. Internal cleaning and a carb kit is the remedy but each and every small opening must be clean. Re-clean the carb and get that screw out. I have had to re-do a carb several times, due to missing just one small hole.
Let me know how you make out.
Michael
