So I've got a Magnum NX with the .18 in it. It's got about a 15 tanks run through it. I was originally having some issues with it getting too hot and bogging down until it quit (even when it was running rich it would bog and quite). I cut some vent holes in the body which seemed to help. I ran it a few times this past weekend and when I went to pull the starter, the string just snapped. I proceeded to take off the engine and the pull start and noticed that it had actually melted the string. The strings that were coiled up inside were also melted and came out in clumps. Has this ever happened to anyone else? I know for sure the cord recoiled back into the engine after It ran so it's not like it was sitting on the exhaust or anything. Can I just run down to the hobby shop and get "pull string"?

Thanks,

Dave
