RE: A not so SUPER TIGRE
I am another unhappy ST buyer.
I have a ST75 that also will not shut down, the carb barrel does not seem to close completely unless I remove the end plate that carries the fuel nipple. With the plate in place there is a significant opening on the barrel still visible.
This motor (which was one of the older Italian jobs) used to live in my TF Corsair until I got tired of dead sticks.
Also had a ST61, this was no better at staying going, I sold it cheaply to someone after telling them the full story.
