Not often we see a lawn mower thread, so I hope you don't mind me showing a few pointers for your Honda where you don't need to go and find a Honda shop or pay OTT....????
Pull start cord, Thaiwatsidu, 5bht a metre.
Pull start handle that doesn't hurt your hand, made up out of a few plastic electric conduit fittings...
An old style throttle lever that stays where you want it, new from Lazada, think it was 30 bht.
The local bike shop made up an inner and outer cable to my measurement to fit the lever, think that was 150bht..
Food for thought.....????
