I have a Magnum FS 120 on the front of my W of M 120 Ultimate ARF.

As this is my first 4-stroke I have been trying to read as much as possible from the net and follow the manufacturers guidelines. I have not been able to start this engine for the past two days. Today I re-routed all the fuel lines to by-pass the refueler valve to ensure an unrestricted flow to the carb (via a filter). The engine will fire on occasion (so I know the glow plug is working and juice from the battery is not a problem), then it does nothing. When it does manage to start it runs for no more than 5 seconds and dies.

There is plenty of fuel, I've adjusted the needle valve and attempted to start with the recommended 2 1/2 turns of the needle up to a full 3 turns and even at only 2 turns of the needle and nothing seems to work. I understand the larger 4-strokes need to be "wet" to start, but I have done that repeatedly, no hydrolock yet. I went and calmed down for a while and let everything drain and started over again but the results are the same. As a last resort I let everything settle down, applied power to the glow plug, grabbed the starter and tried to get it going, just like I do with my 2-strokes, it fired, ran for a whole 8 seconds and then died.

I reset the mixture to the factory settings and tried but to no avail.

I am going to buy a new baseball bat, hopefully I won't need to give it some Louisville encouragement!, any suggestions, please tell me I am doing something obviously wrong.

Cheers

Dave
