The adjustable engine mounts can interfere
with the bottom case of the engine.
As you can clearly see with this STS DB 21 engine the bottom cooling rib
is obstructing correct mounting. You can remove the rib or other obstacles
with a file so these engine mounts can be used. Or use the optional ONE
PIECE engine mount from Hong Nor.
Fit 3 x16 mm hexagon screws through the engine mounting holes.
Fit at the bottom of the screws 3 mm lock nuts a few turns by hand force.
Slide the engine mount over the 3 mm lock
nuts and tight the 3 mm hexagon screws using a 2.5 mm hexagon tool.
We have to readjust these engine mounts so only tight them lightly.
A quick test can be done with a break off
knife blade if the engine mounts are flat.
If this is not the case make sure the engine mounts are free from the
crank case.
