Small Engines (Lawn Mowers, etc.)/Honda EB6500SX fuel solenoid


Good afternoon. i have a honda EB6500SX that im having a small issue with. it was running fine with no issues up till about a week ago. it will run for a bit then stop. when it stoped and wouldnt start again i check the 3 sources. i have a good spark, the air filter is clean. im getting fuel to the carb. i pulled the fuel solenoid out cleaned it. i tested it with a 9 volt battery and it didnt retract the plunger. am i not testing it correctly? if i am then the obiously the soleniod is bad. Am i correct to understand that this only prevents back fireing? would it be out of the question to just not replace it and just plug the hole it came out of. I know im getting gas in the bowl with no issue that was appent when i pulled the solenoid. Any insight wout be apprecated. Thank you in advance.

Do you have the 2 wire fuel solenoid?  If your 9 volt battery is good you should be able to activate the might need to reverse the wires to be sure you have the polarity is correct to verify the solenoid is not working.

You are correct about the purpose of the fuel solenoid...prevent backfiring.  If you can find a screw with the proper threads you can just block off the hole...but the screw needs to be short.

I have seen some solenoids where the customer just cut off or removed the plunger...worked but sure looked weird.

Can you move the plunger in and out by hand?

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.
