Running an SU carb yeah? first you need to make sure you are using the correct needle and spring for your engine http://forum.suzukiclubuk.co.uk/vi ... =13&t=2249

Then run your engine up to temp and check the timing is correct

Don't forget to make sure your dash pot is full to the correct level and preferably the correct grade oil, straight sae 20 weight oil is best and what you'll find in a bottle of SU carb oil.

When adjusting the carb blip the throttle and let is settle between every adjustment.

how to tell that your mixture is right when tuning by ear. Once the engine is up to temperature remove the air filter and use a screw driver to slowly lift the piston 1-2mm while it's idling and listen to what the engine does......

If it stumbles and the revs drop you are too lean so enrichen the mixture. (don't forget to blip the throttle and let it settle)

If the rpm picks up slightly (50rpm or so) peaks and then drops back to idle you are about spot on.

If the rpm picks up and continues to rise then you are running too rich.

I sort of do a combo of the above and also listen to how the engine picks up when you move the throttle, a few quick blips of the throttle and a steady rise etc.

I took a different approach in the end.

Step 1. Get your car running, no matter how rough,

Step 2. Drive 214 miles to wagtail.

Step 3. Let the zuk boffins tinker for 20 mins,

Step 4. Enjoy a tuned SU.
