We'll see. I ordered 4 NKG's for my'76 Batavus and will try them. The repair manual recommends Bosch, but I'm unable to find anyone in the area that can order them for me.
The previous owner was running a 16:1 oil ratio and I'm going to try 32:1 to see if that helps take the deadness out of the engine. The Batavus repair manual says that 50:1 is the normal ratio, but being unfamiliar with this moped's background I'm going to error on the conservative side for the oil ratio.
I'm getting the gas tank lined with Kreem because of the pepper rust that's going through the fuel line to the filter. Then maybe I can get an after market shutoff valve and it won't clog from the rust.
