If you have tried to find a pull start for a K4.9 or 5.6 engine, you will know that they are very difficult to find as they use an unusual 9mm or 11mm hex starter shaft. In fact they are no longer made, and most stocks have now been depleted.

This is a replacement Pull start kit that contains a starter shaft that converts the 9mm/11mm  hex to a 12mm hex allowing the use of a modern standard pull start. The kit also includes a high quality "stronger than steel" unbreakable cord pull start and bolts to fit the HPI Engines.

If you break this cord, I will replace it free of charge.

Kit contains

1 x 12mm Starter shaft to replace existing 9mm/11mm shaft
1 x Pull Start made with Kevlar / Carbon Fibre cord (stronger than Steel)
4 x Pull Start bolts. 2.5mm x 10mm Hex head.

Pull starter case measures 27mm between fixing hole centres and 32mm across the complete width.

Please note the K4.6 and 5,9 engines are high compresssion engine and cheap pull starts will not be strong enough for these engines. 

Note* Only the cord is guaranteed. I am unable to guarantee against brut force breakages, or against any damage caused by engine malfunction. Whent starting you engine use "short sharp" pulls and never pull to the end.
