Just picked this up from a backyard mechanic.

The engine is smooth, quiet and quick but feels boggy . I am definitely not used to 100 to 1 so I may have mixed it a little rich.

Is it possible to put a 15 carb on this model ?

Where is the low speed idle adjustment ?

Where is the lean / rich low speed jet adjustment ?

Can't deny the quality build. SOLID !

Starting to believe.

I've located the idle speed adjustment and set it to 700 - 750 RPM

Where's the low jet / lean / rich adjustment ?

It is all detailed in the applicable service manual.
 
I just bought the motor and didn't buy the manual yet.

What's so hard about sharing the location of a simple screw
