SIP 360 ignition adjustment gauge for Vespa 83002400

Properly set ignition timing is essential for any engine.

The SIP digital Gradimeter is a very practical tool that should not be missing in a well-equipped workshop, it allows an optimal configuration of the ignition point of the engine. It can be used on two and four-stroke engines, regardless of whether it is a Vespa or a vintage Lambretta or a two and four-stroke automatic scooter 50-180cc. To facilitate simple and precise positioning of the gradimeter, the SIP graduated disk is equipped with three holes to accept long fixing bolts. This allows mounting by simply drilling three holes in the battery compartment, making it even easier to read the times.

Instructions:

1. Determine Top Dead Center (TDC)
2. Mark the position of the arrow on the flywheel on the crankcase with a marker.
3. Attach the degree disc and align the 0 with the marking on the crankcase.
4. Also mark the desired ignition point (counterclockwise) on the crankcase.
5. Remove the degree disc, start the scooter and with the help of the strobe light check the desired ignition marking lines with the arrow on the flywheel. Readjust the position of the stator plate until the correct position is found. To save time and effort during maintenance later, permanently mark both the crankcase and stator to record their position in relation to each other.
