Paul & Seth (18 Months) hard at work
OUR Go-Kart - based on the raven but some small changes. Cost about
$400 to
build.
Early photo - petrol tank
mounted on
engine - Soon broke free, now on back of seat. Good old Victa 160cc.
2 stroke lawn mower engine, approx. 1980 vintage. Removed old plastic
body
carby and fitted an aluminium
carby with butterfly throttle ( from an older model Victa mower ).
I machined 1mm off the
head in a
lathe. Enlarged the gas transfer slots in the barrel and inlet &
exhaust
ports with a rotary file. Home made stainless steel exhaust. Engine
5500 rpm (measured
before being modified).
Geared down to 10:1 and 13" OD rear wheels, 10" OD on front. Top
speed of 35K and will climb a fairly steep
hill. A good all round off road buggy.
There are electronic
modules
available from lawn mower repair shops that replace the points and will
provide
a
useful increase in power at the high end of the rev range. The cost of
these
things are about $25.
Solid 1" BMS back axle
makes it
hard to turn tight corners on concrete or bitumen when going slow, but
it will
go almost anywhere on rough terrain. Mechanic linkage on to a 1/8"
thick
disk of stainless steel 8" dia. gives
good brakes - I used the second hand pads out of my Ford Laser.
Here is a drawing of the
disk brake
setup
