First off I am special ed. when it comes to these engines...(or maybe impatient)I have a seagull edge with a super tigre g90 on it. I bought the engine used on here........with about half a gallon of fuel in it. It is not fully broken in yet. Which buying it used could be the problem I know, but money is tight for me. The engine appears great and almost new and still has warranty left.I cant seem to get the engine to run right. I take off the glow heat and it dies everytime.It runs great with the glow heat on but take it off and that is it.!!! I have tryed glow plugs with no result. Maybe the fuel line is to small????. The tank is ok and the clunk is free from the back of the tank.......... Any help???????????????
