RE: [Honda-C70] 1981 C70 Passport - Getting it Started..

You said gas is flowing to the carb , but you also said no gas comes out when you open the drain at the bottom of the carb. That is a contradiction. Try turning the petcock to off & removing the 2 screws that hold it to the side of the carb. Hold the petcock over a clean container & turn it to run then reserve . You should get a good stream in both positions, & shut off tightly in the off position. If you don`t get gas the fuel lines or the tubes in the bottom of the tank are pluged . If gas flowed well there is the possibility that the float is stuck in the closed or up position . If a couple of raps with the handle of a screw driver doesn't shake it loose. You will need to get inside the carb to find out why gas isn`t getting in. Good Luck! Baby Huey

Subject: [Honda-C70] 1981 C70 Passport - Getting it Started..

Before I take off the new carb I put on last year... am I missing something obvious?

Gas in tank
Flowing to carb
Petcock on
Run on
Switch on yolk (no key) is on.
All lights in place.
Choke on
Battery fully charged.
Throttle cable working
Runs for a bit if I spray that quick start in.
If I open the drain at the bottom of the carb nothing.
If I tip the bike nothing runs out.
Blowing and (sucking) on the vent tubes nothing..
Is there some type of vacuum that needs to get established?
Should I be able to flood it by opening the throttle and tipping the bike?
Best advice...
We had one almost nice day to be out in the unheated garage... I was hoping to kick it over and have it aimed at the door ready to ride. Michigan weather sucks...LOL
Thank you.
