Honda Passport C70 Choke/Carb Issue?
Just recently purchased a Honda C70 Passport scooter. The thing was garaged for the last decade so hasn't seen more than 100 miles in the last few years.
The bike has been running perfectly up until yesterday. With the choke off (pushed in) the bike still revs very very high, as if the choke is still out, and when I pull the choke on (pulled out) it seems to idle lower and then rev very high again.
Wondering where I should start looking to remedy the situation. The cable seems to be engaging/disengaging the choke.
Could it be that the carb needs to be dipped, cleaned? Jets? Floats? Not too familiar with carbs other than the basic assembly…
any and all help appreciated! 
Inspect little things first.
Check the air filter - clean or replace as necessary.
Check the air box intake - small animals like to build nests in tight areas.
check the condition of the intake manifold - specifically for cracks and a tight seal to the carburetor.
Next would be to remove the carburetor - completely disassemble and clean it.
- Where can I find a genuine 1994 Honda Fourtrax carb no aftermarket stuff? Can't seem to find one only aftermarket junk already bought one and it wouldn't run properly, thanks in advance
- Motorcycle dies when I turn off the choke? I don't know much about motorcycles just started learning how to ride from my boyfriend. I decided I'd ride my motorcycle to the store today to get some more experience so I started it and let it run for a few mins with the choke on and then when I took the choke off it just died. Could that happen if it needs gas? It has some gas in the tank but may be low. I'm hoping it's nothing serious. It's a Honda Rebel 250
- Motorcycle choke stopped working suddenly? I have a 1986 Honda rebel 450 that has never had a problem starting. I always use the choke if its cold and its always worked perfectly. However, the today when the bike was running, i put the choke on to see if it was working and it had no effect on the idle whatsoever. I now can't start my bike easily since the choke doesn't work. Does this sound like a bad choke cable? Is a choke cable the same as a throttle cable? I can't find them anywhere.
- Motorcycle choke not working? My choke stopped working on my 86 Honda rebel 450. Someone was messing with it the other day and found out that if you tug one of the cables, the choke on the carb opens up and is the same thing as applying the choke the regular way. The problem is, i can't figure out what he was doing and how he go the chok to open up. Any ideas what he could have done?
