Thanks for the responses. I've tried two new glow plugs including one that has an idle bar. Nothing seems to work. Called my LHS and they think the low idle is set too lean. I've already pulled the carb barrel and replaced the HS needle and am still getting the same issue.

I know everyone says OS engines are the best and all. But in reality, I'm learning every engine will have its issues. Now that I'm getting a taste of engine issues, it's making me less hesitant to try out a Super Tigre.
