I have a ST4500 converted to gas. It has the Pro Spark ignition system using a 1/4-32 spark plug. I had needle bearings put on the con rod as well. Plan on converting my BGX-1 as well. Hey Max, how much do you charge?
I fit the wabro support, walbo mnimagnet and hall sensor no need con rod bearings, I ported it. is very powerful more power full than my zdz 40cc
u can instead use a walbro use regulator and is nice
