SP250 Dwell angle
Posted: Fri Feb 14, 2020 8:38 pm
Good evening guys,
Today in France, it was a sunny day ! A good time to have a ride with the SP250 currently into my workshop.
The ride was a real pleasure, the engine, recently and completely rebuilt, seems to run perfectly. Once back at my workshop, just by professional consciousness, I decided to check up the dynamic ignition timing and the Dwell angle. For that purpose, I use a Gunson G4123 Supastrobe Professional.
10°BTDC at 750 rev/mn : perfect. But concerning the Dwell angle, 98% !!! Can any engine run with a such Dwell angle ?!? The data given by the official handbook is 32% !! Should I incriminate my device or should I adjust my contact points gaps ?
Thank you,
Julian
