Have a running honda gd411 set up in a van of mine. its a pull start, ive got the knack and can fire it on the coldest of days, But i have a spare engine that runs, (rings have gone and smokes, also stop lever is broke) and this m/c has the key start. ive a plant fitter looked @ converting my pull start too key start with parts from my spare m/c, he quoted lottery numbers to do the job. Can live with the pull start system, but looking to make life a little easier.
has anyone converted. or any advice as to conversion apprec.
