When we
look at fuel/oil ratios in the 2-stroke mix, it’s worth understanding the
affect that changing the oil/fuel ratio will have on your jetting. If you
increase the oil content, you are effectively reducing the amount of petrol
(gas) in the mixture. The converse is also true so reducing the oil content
is effectively making the mixture richer.
Getting your fuel/oil ratio
wrong will at best affect the jetting, at worst it could mean damaging your
engine!
There are many measuring jugs
available but to use them accurately is very difficult. They need to be
placed on a level surface - try finding a level surface when you're at the
track! The wider the jug, the more difficult it gets to fill it to the exact
level. When you empty the oil into your fuel, residue is left coating the
inside of the jug. |
