Rebuildet the engine today, and the rear axel. I really don't know what i have done wrong, but now it goes from 0-35 mph in a flash... fun thougt... but with a steeringweel with 3 inch slip makes it funny with a twist...
Changed out the fuelpump from old school manual pump, to electrical fuelpump. Took some time to work out the wirering, but.... well it works.
