These jets will fit all Arreche/Amal carbs from 17.5 to 21mm choke size.To set the carb up one usually starts with an overlarge mainjet. This will cause the engine to missfire (fourstroke) on full throttle. You then gradually decrease the mainjet in size (in steps of 5) until the engine starts running properly. Finetuning is then achieved by juggling around with the in-between sizes. Be careful: too small a mainjet will result in a lean mixture and piston seizures.
