The damping of the mounting hould be cho en a hard a po ible, becau e engine could
way/ wing it elf with damped mounting which i too mooth. Thi lead to problem with
the fuel mixture (i.e. foam up of the fuel, uncontrolled centrifuge of the fuel pump diaphragm)
and o to an un afe running of the engine.
-Recommendation for fixing:
Engine i mounted on a tabile fixing plate that i nearly doubled a the bottom ide of the
engine (the bigger the better). At the two exterior of the fixing plate there will be fixed, in
axial way, four hard rubber damping element (on each ide two element .
Thi complete ba e will be fixed by the e rubber damping element on an according ground
plate that i connected trong with the in trument.
1.2.2 Air suppl of the engine
The engine ha to be in talled in that way, that the upplied fre h air i ufficient for cooling
and for the carburettor.
For an enclo ed in tallation it ha to be en ured that hot exhau ted cooling air i not upplied
to carburettor, becau e thi lead to dra tic reduction of power.
Al o it ha to be en ured that hot exhau ted cooling air could e cape from ca e without
ob truction, becau e thi lead automatically to an overheat of the engine and o to de truction
of it elf.
Sufficient fresh air suppl has to be attended.
1.2.3 Fuel suppl of the engine
1.2.3-1 F 33 A
The fuel upply of the engine i upported by a diaphragm pump (Illu . 1.2.3-1), which
pu hed through crank ca e low pre ure.
Illustration 1.2.3-1 (Diaphragm Fuel pump)
Thi diaphragm pump i ituated in ide fuel line between the fuel tank and carburettor. A fuel
filter alway hould be mounted between the diaphragm pump and fuel tank.
The diaphragm pump i tied at crankca e.
