I had a Super Tigre 75 and it used to spit raw fuel when it was running (out the carb, by the way) but it started easily, ran good, and had good power. So, I don't know what to tell you any more than I've already said.

Perhaps taking it to the field when there are experienced flyers there and maybe one of them can put a finger on your problem and get that engine running.

Good luck.
