Timing and hand throttle levers

[RHD]

Centre punch the ends of each rod, and using a 1/16” drill bit drill a small shallow 1/16’ hole in the end of each.
Push the two control rods through the new or good condition top bush and down to near the exit points on the steering column. Using a small unwanted screwdriver, grind a point to the end, and push the screwdriver unto one exit hole until you make contact with the control rod hole previously drilled. Once the screwdriver tip has entered the small hole, gradually bring it through the exit tunnel and do the same with the second.
Fit the springs and toggle arms and re-pin. This is easier said than done. The spring must me compressed considerably to get the pin to enter the hole in the end of the control rod. (Swearing profusely at this point will not help one bit.)
