JR Pedersen 18 #1 Posted August 8 Last night I was cutting my grass for about 30 minutes and everything was working great...shut it off for dinner and came back and it would run for 30 seconds only on "Full" Choke and then stalls. Any ideas what might be the issue? Share this post Link to post Share on other sites
953 nut 60,352 #2 Posted August 8 Could be time to do some fuel system maintenance. Is there gas in the tank? Are you using gasoline with Ethanol? If you are then STOP. Ethanol will kill the fuel system. You can find a station that sells real gasoline on this site.https://www.pure-gas.org/ Check the outlet from the tank to see that it is not obstructed. Replace the fuel hose and filter. Check the fuel pump to see that it is pumping. The carburetor may need to be rebuilt. 2 Share this post Link to post Share on other sites

ri702bill 9,534 #6 Posted August 8 Dad'd 702 did the same thing. It ran great until you shut it off. The rings are quite a bit tired - carbon would bridge the spark plug gap giving a no start condition. An inline spark checker shows it HAS spark, but it is shorting out. Clean the plug, it starts right up...... 1 Share this post Link to post Share on other sites
