looking for anyone out there that may have timing specs (or any tweaks that may work better) for Joyner 650 Sand Viper.
Looking for initial timing (idle timing), total timing and timing curve.
I have an aftermarket Weber 34 ICT carb and running Joyner performance exhaust. All ignition/distributor/etc. is stock.
Thanks,
Papa Buggy

Timing advances via a spinning weight and by vacuum. Many people block off the vacuum and just set idle advance somewhere between 25-30 degrees based on what runs best for them. More advance may require higher octane and ambient temperatures may affect how much advance you can apply before getting pre-detonation.
