Pull Starter Hints
The pull starter as tted to most of the entry level engines is, if
treated correctly, the easiest and most cost eective method of starting an
engine. As with every silver lining, there is a cloud. The pullstart system is
similar to that of a lawnmower to look at, but that is where the similarity
ends. The pullstarter is susceptible to breaking if the engine is ooded or
not lubricated enough. To ensure this does not happen, a few simple rules
should be followed.
1. Before attempting to start the engine from cold, remove the
glowplug and then prime the engine with fuel. For cars with a primer
button on the tank, press this until the fuel has travelled along the fuel
pipe to the carburettor and then a further 10-20 presses. For cars without
a primer on the tank, pull the pullstarter rapidly with your nger over the
exhaust pipe outlet until the fuel has travelled to the carb, and then a
further 10-20 times to lube the engine.
2. Then turn the car upside down and pull the pullstarter rapidly until
all the excess fuel has emptied onto the oor through the glowplug hole.
Ret the plug ensuring the copper gasket washer is also retted. Wind it
all the way in and then re-wind 1 to 1.5 turns. This allows gases to escape
thus lowering the engines initial compression.
3. Start engine. The engine will run “lumpily” or stop after a few
seconds so try and keep it running by blipping the throttle. Tighten the
glowplug while the engine is running if possible. If the engine has stalled
restart with the plug tightened.
The above procedure hould always be followed from cold or if
diculty with starting is being experienced.
Flooding of the Engine
The most common cause of engine and pullstarter damage is from the ‘ood-
ing” of the engine or a hydro-locked. More accurately this is too much fuel
inside the engines crankcase causing the piston to lock. The piston rises to the
top of the combustion chamber and instead of compressing a gas i.e. fuel/air
mixture it has to try and compress a liquid, fuel only, which isn’t possible. This
puts massive strain on the piston, conrod and crankshaft as well as the starter.
Invariably one component will fail, usually the conrod causing massive damage
to the engines internals.
To avoid ooding the engine, always start the engine from cold using the meth-
ods mentioned above and if at any time the engine becomes dicult to turn
over with the pullstarter, then remove the glowplug and empty all excess fuel
out and start again. The pullstarter assembly can only be damaged by either
over extension or a ooded engine. So if you break a pull start this is possible
warning of a ooded engine.
