Precision tuning of the carburetor

The use of a tachometer is highly recommended. And, again, never adjust the needles while the

engine is running!

1. Using the tachometer tune the engine for maximum power with the high needle (H).

2. Again using the tachometer; richen the high needle (H) until the motor runs 100-200 RPM

less than the maximum RPM. Now you are tuned slightly rich on the high needle (H).

3. Let the engine run at idle for one minute. Check to see that the idle RPM remains constant.

4. If the idle RPM drops until the engine stops; the low needle (L) is too rich. Lean the low

needle (L) until a constant idle RPM is achieved.

5. Check the transition with a quick throttle advance. The engine should not sound strained

at any time. It should sound like it is making quick steady power; without any hesitation.

6. An optimally tuned engine will feel a bit rich after a cold start. It will start to run right after

it has warmed up for approximately one minute.
