[Kartbuilding] Fwd: Clutch advice

[Stephen Burke]

Hi Stephen
Thank you very much for making this great site, its very hard to find
info about go kart building on the web and you have helped me a lot with
your advice and drawings, as i cannot currently weld and wish to make a
go kart i found a very sturdy "berg" style go kart but its built like a
tank the back axle assembly is made of 6mm steel plate, i got it at a
local farm and industrial shop for 200 euro. Anyway I am removing all
the pedals and i am going to adapt it to fit a 3.5hp briggs and stratton
engine but the biggest challenge i am having is a clutch system i am
thinking of a 1 : 5 gear ratio and an idle pulley that i can tension
with an old hand brake from a car, But i think there might be problems
taking off as the rpm of the engine doesn't change that much it goes
from around 3000rpm to around 4000rpm.
So i went in search of a centrifigul clutch but was told that these
would disintegrate on any kind of rough terrain or slope so the best
option seems to be a torque converter, i found a good one called the
"torq-a-verter 2" it adjusts torque itself to suit the terrain and has a
clutch built in. http://www.kartworld.com/TORQ-A-VERTER.htm but its 180
dollar which is around 150 euro so that doesnt seem to be an option at
the moment. So what i really want to ask you is do you have any advice
on which option to go for i will probably try the idle pulley method
first and if that doesnt work ill have to invest in a torque converter.
I will include a few pictures of the kart there are five pictures they
are around 200kb each.

Thanks alot for you time
P.S  Did you hear of anyone else adapting a "berg" go kart to fit an
engine if so please tell me about it
P.P.S I am in Ireland and its very hard to find places that sell go
kart/ engine parts if you know of anywhere please let me know thanks again
