Gummed up passages are not unusual. For dried out fuel residue in passages I soak in laquer thinners.. The last carb on a smaller engine had apparently developed white corrosion in a small passage located where I could not accesss it as far as I could tell. Had to get another carb.

the white corrosion is due to water getting into the carb (being stored outside maybe) and reacting with the aluminum.

Yes, the carb is shot in that case.

Good tips on this thread!

Thanks for the increase in my small engine knowledge level in why I was having to use choke on one of my vintage Honda motorcycles I owned.

For the Honda carbs, the jet is not in the bolt that holds the bowl. Instead, the jet is screwed into the center of the carb (after the bowl is removed). If turn the carb over and look in the center, you will see a slotted brass jet. Use a small slotted screwdriver to remove it. Just clean that and it will run like it should- no more choking it to run.

There is a particular model and years of a late '60s to early '70s Honda MC that I just adore. The '68 through '73 Honda CL 350. I owned a brand new '71 CL 350 model in the day, sold it after a year, then years later in the early '80s bought an example of it, then sold it in the early '90s. Wish I wouldn't have because I can't find one near the condition for the money I sold it for.

I want like three of 'em now! If I can find 'em. They don't have to be perfect, either. I definitely want a '72 and a '68.

'preciate the help/tips!
