    HOMELITE 30cc

    Hey guys,

    I've got a nice Homelite 30cc. It has the late model narrow rings (which I like), and large transfer ports. The pic shows the exhaust port as it came out of the machine; very little...
  2. Sticky: The best check is to look into the exhaust port...

    The best check is to look into the exhaust port and see what the piston and rings look like. If the piston is smooth, shiny, and a bit oily it is probably a good candidate for rebuild and hop up. ...

    If you can find a file that is narrow enough, like a flat jewelers file, I would use that. If not, a cutoff/grinding disk in a Dremel tool will work, but man, be careful with that.

    As I mentioned in the first sentence of the posting about pinning the piston, the pin should be whatever you can find that is about the same diameter as the width of the ring groove. It is a bit...

    Yep, it will draw that far no problem. It'll take a few flips with the throttle opened slightly and the choke shut to get the fuel to the carb the first time, but after that no problem. I put all...

    So are you saying that you probably use about 11 or 12 ounces for a 12 minute IMAC flight?

    You need to check with the manufacturer of the probe, and be sure they know it is going to be used on a small, model airplane engine. The distance from the piston is critical for getting the correct...

    32:1 is a good mix for that size engine. Regular gas is fine, premium gas would actually cost a little performance.
