Trouble starting...needs throttle opened to catch?!  By  markavionics (Read 1,196 times)

It could be both ways, too rich or too lean, your air filter might be too restrictive, I've had that issue before, try tuning the carb without the air filter, just the bare carb, it won't hurt the engine to do so just to check everything is ok, then if you find a setting that works fine without the air filter, put the air filter back on and check if it still runs fine, if not, try adjusting the A/F a bit, if it doesn't work, get a less restrictive air filter.
