FAQs

What oil and fuel mixture ratio is specified for the 5HP/6HP models?

The document specifies a fuel-to-oil ratio of 50:1 for the mixture. It also describes using the recommended outboard oil or an equivalent automotive oil type if necessary.

What are the spark plug and magneto point gap specifications?

Spark plug recommendations list Champion J4J, AC M42K, and Autolite A21X, with an electrode gap of 0.030. The magneto point gap is listed as 0.020.

How is the carburetor float level set for proper operation?

The procedure instructs moving the carburetor, unbolting and removing the float chamber, then inverting the carburetor body to check that the float surfaces are level and flush with the gasket surface. If not, the float lever is carefully bent and rechecked after assembly.
