Recently bought a Laser 75 4-stroke. Do some four strokes not start well by hand?
It seems the only way to get it going is to flood it with fuel, turn it to the compression
stroke, add glow juice and flip counter-clockwise. If it doesn't start, I need to immediately remove the glow juice and repeat the procedure. This works only a small percentage of the time. Backflipping (clockwise) doesn't work because the engine doesn't seem to make enough compression backwards. It doesn't seem to have a lot of compression counter-clockwise either, but when it's running it idles and
transitions well without glow power. It wouldn't do this if the ring was shot would it?
All of my 2-strokes start easily by hand so I got rid of my electric starter. Do I need a new starter or a new engine? Ross
Are you sure that the throttle was open when you checked the compression? A four stroke with a closed throttle has almost no compression because the carb is not letting any air into the cylinder to compress.
