adsm08 4,323 #1 Posted 23 hours ago The boy went to mow tonight and couldn't get the engine to start. I took a look, and fuel was running out of the carb. So I took it apart, checked the float and needle, they are working at best I can tell. They pass every test I know, I can flip the carb over and not be able to blow through it, I can hold the float up and get no fuel, I can let go of the float and it drops, along with the needle. But as soon as I put the bowl on and prime the fuel system fuel starts running out of the carb. This is one that has had an electric pump installed. Aside from the pump overwhelming the float I'm at a loss. Share this post Link to post Share on other sites

Are you using the little bent wire clip that loosely attaches the float to the needle? Improperly installed, it can cause the needle not to close all the way....

Shortly after I built the flame it started spewing gas. Yep pin hole in float. I was too stupid to pull the float off and check it just dropped the bowl and checked the valve. I had the bowl off ten times before I got off the recliner and checked the float. A very small hole and just for $hit$ & grins tried to repair it. You know just to see if I could. Enlarged the hole with a dental pick and shook the gas out and set in a warm place to further evaporate it out. Then just soldered it shut. Being brass soldered up easy. Still working to this day. I had pics if I could find them ... Edited 10 hours ago by WHX?? 1 Share this post Link to post Share on other sites

I hate to admit it, but the little bent wire has bit me a couple times in the past. I've never heard of a e pump going bad and start making more pressure but guess it could be possible.

peter lena 9,821 #10 Posted 10 hours ago @adsm08 have electrics on my units , 2-3.5 PSI , no issues at all , sounds like a VERY TYPICAL COLLECTIVE ISSUE , not one but EVERY stage of FUNCTION , would recommend an entire carb swap , remove it from the problem , start fresh , like a fuel check valve and filter just before carb ? clear fuel line , verifies standing clean fuel to carb ! have that basic on all my small engines , stand by gen too , no issues , pete Share this post Link to post Share on other sites
