This morning I finally got some time to goof with my carb some more. After soaking it in good ole' WD-40 for 2 hours I was able to push the emulsion tube out with very little effort with a small flat head screwdriver from inside the throat. I then finished cleaning the entire card, changed out the spark plug, reassembled everything...three pulls and it starts and runs like new...no sputter, no miss...it's back to perfect. THANKS TO ALL OF YOU FOR CONTRIBUTING IN THIS THREAD!
Best news this year!!!!
Did you find anything in the tube? Was the end of the tube that protrudes into the venturi area discolored?
Jim
The tube had your typical gluey crust of old hardened fuel clogging almost all the holes. I cleaned all the holes using a mini drill set from harbor freight. No discoloration anywhere though.
Wayne (Reddog1) and I did a mod on our honder's last year...
We installed an extended almost clear fuel line and added a glass filter found in auto parts places. He has experienced numerous carb problems, me, 3 times. My Honda is about 4 years old.
Last week we did an inspection of our fuel system....
His had a weird sediment, mostly liquid but like a syrup in the loop of the fuel line along with some in the filter. There was also some fine contaminants..
We put the gas/syrup in a clear bottle and removed as much of the gas as we could....The syrup was thick as molasses....We do not have a clue what it was but he was thankful that it had not entered his carb.
Wayne's honda probably has more hours on it that most of us...It was his primary source of shore power for a few years before he got solar.
The discoloration I was talking about is that the tip of the emulsion tube that protrudes into the venturi is gray in color.
We saw that with Wayne's tube....Initially his was difficult to remove if I recall.
The syrup really bothers me....I have older Briggs Stratton engines in everything... 2 riding mowers, rototiller, pressure washer, chipper shredder etc....I have not had a carb problem on any of those devices....I have never drained the tanks to take a look.
I have many old VW aircooled carbs that I have taken apart to rebuild..See lots of dry powder corrosion, never anything like what we saw. These carbs were all pre-mtbe/ethanol.
