Re: Starts cold, runs, hard time restarting when warm.
I would suspect you have done some damage to your bore from being too lean. You need tio pull the jug (cylinder).

Re: Starts cold, runs, hard time restarting when warm.
What do I need to do to fix it? Is any thing salvageable? It's it time to just learn to live at 41mm?
