RE: Four Stroke Glow To Gas
It would cost something in the neighborhood of $500 to convert to gas.
1. 2ea CH ingiions @$170 ea
2. Custom needle valve and needle valve body, finer threads and longer taper
3. Custom throttle barrel, you need a barrel groove that is sorta like expo. Leaner in the mid range
4. An oiling system for the lower end, remember that these engines are lubed by blowby fron the cylinder. The only oil in the bottom end carried by the blowby. You will burn about %50 less fuel using gas sooo the lower end gets less oil. And you now need an oiling system.
