my tiller has been sitting in my garage for over a year. I took it out yesterday and would not start. I put a new plug in it and put a little gas in carb. it ran till it buned the gas/oil mix in the carb. would not restart without pouring gas into carb. Does this tiller have a primer like gas blowers,chain saws ect.? Need help staring. Mine has NO compression button. Also used choke. there is a lever under the carb that opens the baffels in the card. are they to poistion certian way?
