Hello; I have a Laser 100 in a Taube that I don't fly very often, to start it I fuel it up then hold a finger over the carb opening and turn the engine over anti-clockwise until I hear the goosh-goosh sound that tells me that the engine is recieving fuel. I then put the glo driver on it and turn it clockwise until it gets stiff, then I just twist the spinner nut clockwise, with the throttle at idle, it usually starts right away. If it fires but doesn't start, I take the glo driver off and prime it again, goosh goosh, and twist the spinner nut clockwise again and away it goes.

One thing with my Laser was that the carb is quite high, being mounted right next to the head with a short intake pipe. My carb is higher then the fuel tank, and without muffler pressure behind the fuel, your fuel hoses have to have a good connection to keep the fuel running to the carb or you'll lose your prime, and it will be difficult to start and run.

Most other flyers at our field have a starter, so if I am having any difficulty starting it, someone will drag their starter over to where I am and offer to spin it over for me. I don't think I have had to use a starter on that engine more then twice in all the time I've had it. It always amazes newcomers to see how easy it starts, and how quietly it runs, and how low it idles.
