This engine is certified to operate on
unleaded gasoline and with the
mix ratio 50:1.
Your two-stroke engine requires a
mixture of brand-name gasoline and
quality two-stroke engine oil with the
classification TC.
Use regular branded unleaded gasoline
with a minimum octane rating of
90 RON (U.S.A./Canada: pump octane
min. 89!). If the octane number of the

result in preignition (causing "pinging")
which is accompanied by an increase in
engine temperature. This, in turn,
