Silent IN Zanzottera engine.

Zanzottera MZ 34 and MZ 35 - "The engine was originally designed and
produced by Zanzottera Technologies of Italy, but the design was sold,
along with the rest of the company's two-stroke ultralight aircraft
engine line to Compact Radial Engines of Surrey, British Columbia,
Canada."



"turn wrenches"...it's hard to find a techician willing to learn

Here is a manual dated 14-12-01 :

which gives trouble shooting details.

When I click on the Compact Radial Engines URL, its redirected to this

2 cycle engines do require periodic maintenance...replacing spark
plugs, removing fuel (carb/tank/line) when not in use for a period of
time, would be the main considerations

If engine is still being manufactured, there may be a shop manual for
later built engines
