I have a 50 hp johnson 2 stroke; 2001 model.
Would anyone have a diagram of carburettor so I can identify low speed from high speed jet, or otherwise tell me which is which?
Thankyou

Re: Identifying carb jets

It'll describe the adjustable jet as the low speed jet. The "D" jet in the bowl is the high speed jet. Exactly what are you trying to do?

Try this link as well. It's the OEM online parts catalog. I am not sure exactly which model you have so you may have to go back up one folder to find yours.

As Dhadley said the top jet (Item # 18) is the adjustable slow speed jet and the bottom one in the carb bowl is the fixed high speed jet (Item #19).

Best of luck.

Thankyou both. I have found the diagram of the carby.
Dhadley, all I want to do is see if I can make it idle a bit smoother. Plus I like to know what is what when I look at a motor.

No problem, just figured you might be trying to clean them and were wondering about the passages.
