[klwinter]

1.1 liter opel
2. Stock Solex downdrafts 67½ SR dual carb engine, non-OECS

Issue : starts and runs ok.

After warming up , I have noticed that the motor stumbles when accelerating.. IFI I hold half manual choke, the motor spools up MUCH better.....What should I adjust or change.

What year is your Kadett/GT? . . . i.e. early '67½ SR dual carb engine, non-OECS or later '69-'71 SR OECS dual carb engine?

Yours look like this?



. . . it's the later OECS (Opel Emission Control System) SR dual carb engine . . . any '69-'71 FSM will have complete adjustment procedure in it.

These pages might help, even if they are for the 68 and later (some of the 67 1/2 stuff is like 68).

Rebuild the carb-carbs would be my first step.

The carbs have been rebuilt.
