1. Remove the oil pump. 2. Leave the oil pipe attached to the carb, but cut it off about an inch long and the block it with a screw. 3. Upjet by 2 and start adding oil to the fuel, I use 100ml of good oil in 5 litres (50:1). With a 70 kit you may want more oil though
You'll pros fuck it up. Do you no how to get the variation off? Pull it off then there's a spacer then a little belt going from the crank shaft to the oil pump. Look at the oil pump, undo the throttle cable an undo the oil pipes. Slide the pump off then the belt etc. Then pull your 2/ tank. The pipe connected from carbon to oil pump, cut the pipe down to a few cm, then plug it. Then get a mixing bottle an mix up a tank. Important tired an I've got auto correct on so if anything Iaa spelt weird its ntt me
