Hi there.
I have a polini Thor 200 evo in a zenith frame. I've been having an issue that when I go into a 360 the engine will cut out, normally I just pull the starter and she fires up again. But today the same thing happened and it wouldn't start. Even now I cannot get it started. I've just changed the plug (which there was a spark anyway) it has a walbro carb on it, fuel is getting up to the carb when primed but I keep pulling the starter I would expect the plug to get wet but it stays dry. Feels like the compression is ok? Would be great if someone has any ideas. Cheers, damo.
