Hi mark, do i make those turns on the H and L from the position they are in. I've not touched anything from purchase so assumed it would be tuned already from manufacturer. Now it won't run on idle, keeps cutting out. I did the first four heat 15 min heat periods on idle then ran it for 15 mins on quarter power but since bringing it home it won't stay running on idle even though I've not adjusted anything. Nightmare. Can you help? Explain in detail what I've got to do on carb to tune it. Soz for my questions etc.
Regards
