Hey Evan, thanks for all the great tips. I’m cleaning out the carbs on a 1974 Honda CB350F. I boiled the carb body, jets, and all the other metal components. Im trying to blow through the slow jets but cannot. Ive tried to push through a tiny metal wire, also cannot. Is this the way its supposed to be, or am I doing something incorrectly? Thanks
Pilot jets are ALWAYS the hardest things to clean out. They’re also the jets most likely to get clogged.
On a bike like the CB350F the pilot jets are tiny, making it even harder. Sometimes it just takes a lot of time and effort to get them clean. Let them soak long and hard in carb cleaner. Boil them repeatedly. Keep trying to push wires through them. Blow through them with air. Hold them over a lighter and try to burn it out. Use a combination of everything, it’s a giant PITA sometimes.
If you decide you want to give up just take those jets down to your local dealer, and if they’re any good, they’ll have some replacements in stock. Though they’ll charge you HUGE for them. They can be ordered online for about $3 a pop. A dealer will charge 5x that sometimes.
Best of luck! Don’t give up!
