1987 260E R16/1 question
 

Hi All,

My R16/1 is located right below the brake booster and not really accessible. It is not the rotary type, but the plug in type.

The question is, how does one adjust this to trim for the different types of fuel per the manual since it's not the rotary type. I'm looking at the USA National model. Is there just one resistor inside?

thanks,
