Hi Group!
Recently, a friend who has a 1997 Honda Helix asked me to help him with start ability issues with his scoot.
Issue:
The scooter starts, runs for 15-20 seconds then stalls. Its like someone turns off the scooter when it’s running.
Tried:
I rebuilt the carburetor. Gas fills the bowl and I’m able to drain gas from the carburetor bowl.
I changed the autobystarter to a new OEM Honda one.
There are no vacuum issues.
A new air filter was installed.
I replaced the fuel filter.
Strong battery cranks the scoot well.
The fuel pump is supplying ample amount of gas to the carburetor and passed the service manual test
100-octane gas is being used. Either will not keep scooter running after 15-20 seconds.
The spark plug is supplying a hot spark on test to the cylinder. The cranking test confirms this.
The CDI was the only part I was unable to change out.
What has others exhibited with similar issues? Give me some ideas here.
