I have made a spreadsheet comparing the usual jet needles { Spring Type } found on standard Reliant motors .
Needle Code ; AAT is the normal needle found on most
9.5 compression 850cc engines .
I have compared the following needles against the
AAT .
Needle Code ; AEB is the needle found on most
10.5 compression 850cc engines often referred to as Yellow Tops .
Needle Code ; AAC is possibly the needle for
8.5 compression 850cc engines ?
Needle Code ; ABS is possibly the needle for
7.5 compression 850cc engines ?
Needle Code ; ABQ is an unknown needle I have in my collection of used carb spares so it has come out of a Robin or Rialto I have had ?
