Honda GX270 dies after a few seconds

I have a Honda GX270 9 horse power horizontal shaft engine on an air compressor. It starts easily, but dies in about half a minute. I can start it back up and it does the same thing. I have cleaned the carb, replaced the ignition module (coil) and disconnected the "oil alert", but the problem persists. I acts like it's running out of gas. Any help?

See if you can nurse it with some fuel directly into the carb and keep it running. This would confirm a fuel issue. If so check and clean the fuel system from the tank to the carb(filters, lines....) and verify fuel flow to the carb. Next would be to clean or kit the carb.

If it will not remain running by nursing it, remove the kill wire from the coil and check for spark.

The same thing happened to me. You have bad gas. The gas is old and has started to varnish. The varnish makes the gas sticky/gummy. The needle sticks inside the seat and makes the motor die. Enough gas seeps by and the motor will start again. Clean out the old gas. Put in fresh gas. Clean the needle and seat. You should be ready to go.

Well if my recommendation did not fix the problem (Azis=BFHFixit) then since this post is from 2005...it is probably of little consequence by now

Good tip just the same tho
