That is correct. The only thing the head was re-done to use a 1/4x32 glow plug. This was done about 7 years ago. After reading the Gas/Glow fuel mix and use of a hot 4 cycle pug....I decided to see how the 25cc Homelight would run. On regular 10 percent Glow fuel It starts so easy its amazing. Just a light backwards bump of the prop and its running! With just a few min of running the compression is getting high enough so the electric starter will not turn it over anymore. I kinda like this engine....except for the bad viabration it has at about 1/4-1/3 throttle. P.S. It is realy simple to convert to glow now. You can order a glow plug adapter and its plug and play!
