STARTING PROCEDURE HINTS AND TIPS FOR HYPER 7 PBS
Thank you for purchasing the Hyper 7 PBS Ready To Run buggy. The following tips from our R&D guys will help you get
the car started more easily, especially during the often fraught running in period.
1) Always ensure that the fuel is one of the makes AND blends that we recommend. If not all of the information we
supply isn’t relevant, which may make the car harder to start and set up, or even lead to damage.
2) Fill the tank with fuel then remove the glowplug and washer. Turn engine over with the starter box whilst blocking the
exhaust outlet with your nger until fuel is pumped into the engine. The engine cranking speed will increase slightly
as the fuel lubricates the internal parts. Remove your nger from the exhaust outlet, but continue cranking the engine
for 30 seconds, to clear any excess fuel from the engine. Stop cranking the engine, and ret the glowplug and washer.
NOTE:- DON’T TIGHTEN PLUG ALL THE WAY, LEAVE 1.5 TURNS LOOSE. This will reduce the compression,
lessen the load on the starter box and engine components too. Switch on the radio and car, attach the glow starter and
attempt to start. So long as the carburettor is set correctly, the engine will start, but run ‘lumpily’ due to the engine
being cold and the slackened glow plug. Tighten the plug. If the engine tries to stall, ‘blip’ the throttle gently to keep it
running until the engine warms up to normal operating temp. The car is now ready to drive.
3) If at any time the engine ‘locks up’ or becomes excessively tight, remove the glowplug and washer, and run the car on
the starter box to clear the excess fuel in the engine.
4) Sometimes the piston can become ‘pinched’ at the top of the bore, especially when new. This is perfectly normal, and
will reduce dramatically and probably disappear, during the running in period. If it does lock up, remove the glowplug,
turn the car over, and lever the ywheel over with a large at bladed screwdriver until its possible to turn the ywheel
easily with your nger. Then repeat step 3).
5) After using the car and stopping the engine, turn the ywheel to ‘bottom dead centre’ to ensure piston isn’t pinched as
it cools, causing a problem when restarting the engine from cold. (bottom dead centre is 180 degrees from the tightest
part of the engines rotation).
STARTER BOX ETTIQUETTE
The starter box included in the PBS is the ideal way to start the engine, but only if a few guidelines are adhered to.
1) the car is positioned on the starter box using 4 x adjustable pegs. These pegs ensure the alignment of the ywheel
relative to the rubber starter box wheel. NOTE:- CORRECT POSITIONING OF THESE PEGS IS CRITICAL. The
rubber wheel must not touch the chassis at all when attempting to crank/start the engine, or starter box/motor damage
is very likely (this is not warrantied, as it is abuse rather than a manufacturing fault). A little time spent checking the
alignment, and subsequent regular checks, are essential.
2) the starter box will not turn over a ooded engine (full of fuel) or locked up/pinched engine. If the starter rubber wheel
is turning, and the alloy serrated ywheel is not, the rubber wheel will be destroyed very quickly (again not a warranty
issue, as the rubber wheel can only be damaged by a locked engine and not manufacture). If the engine is ooded,
locked up or pinched, refer to points 3) and 4) above to clear it, before continuing. Failure to do so will cause damage
to starter box and/or engine.
3) Check that the rubber wheel is free to rotate in the plastic starter box case, and isn’t catching on the ends of the slot
in the case (see picture). There is only a small amount of clearance here, and any amount of catching will slow the
cranking speed enough to stop the engine from ring. Excessive weight used to press car onto box can distort the box
case and cause the case to catch the rubber wheel too. If the case is catching the wheel, remove approx 10mm of plastic
from the slot, to allow clearance. Care must be taken so as not to cut the rubber wheel itself though.
Make sure that the locating pegs are the correct distance apart before attempting
to start. The rubber wheel must clear the chassis and only make contact with the
ywheel.
Check the areas pointed out in the picture. The ywheel needs to rotate freely in
the slot. When pressure is applied to the car while on the starter it can press the
outer case against the ywheel causing it to bind. Check this area and remove ap-
proximately 10mm of material to allow for extra clearance. Be careful not to cut
into the wheel.
