Without the priming system, we have to use the MA4/5 SPA carburetor The
SPA means that the carburetor has a sprayer or whatever you call it.
 

I bought an electric primer system from ACS. It consists of two cylinder fittings, some copper tubing and an electric solenoid valve. Primer fuel is taken from the gascolator. The procedure for priming is.

1. Flick on electric fuel pump
2. Press primer button for x seconds
3. Start engine
4. Smile
