Hello everyone. I have a new to me Honda 25 HP year model 2003. This engine is clean as can be and only has 137 hours on it. When I test ran the motor I noticed it idled rough. I asked the owner about it and he said it had not been run in a few weeks and that he always used stabil in the gas and sometimes ran seafoam mixed with the gas and this seemed to help. He also said he always ran the carbs dry after each use.
After getting it home I replaced the fuel, checked the fuel filter etc. However I noticed that with it idling when I pulled one plug wire off at a time the middle one made no difference. I tested the spark and it was just like the other two. I squirted a little gas in the sparkplug hole, replace the sparkplug and started the engine, it started right up and purred like a Honda should for a few seconds until the gas I squirted in was burned.
I suspected a plugged carb so I ran a small container of concentrated SeaFoam through the fuel line, tapped around on the carb but nothing helped. Now I know I probably need to pull the middle carburetor and give it a thorough cleaning.
I have a service manual and it shows pulling the whole intake manifold to get to the carbs.
Is it possible to just remove the air breather and linkage and only remove the middle carburetor?
I'm open for any other suggestions also.
Thanks.
