Gee you sure made it sound easy...

Did not replace the 'O' ring float seal. Sounds like you have the manual which is good. The slow, or pilot, or idle jet is the one. Manual calls it the slow, same part # but with a -45 instead of -43 suffix.

Hardest part is some tight areas around the linkage when removing the carbs. Fortunately I have a special "tool" for these type of things (my 15 year old son who has smaller hands and better eyesight).

The Honda manual doesn't leave anything out, if you read it all (not a guy thing). Good Luck!
