Title: PVL ignition, too little or too much advance?
Post by: John Orchard on April 01, 2019, 05:45:40 pm

The instructions with the PVL ignition states that a 250 two-stroke usually runs between 1.8 to 2.3 mm BTDC ignition advance, my DT1 seems to like it retarded to 1.5mm BTDC for a little more top-end.

What are your thoughts & settings, could l be running too high compression?
