I currently have some fuel lines for a chainsaw on my manual primer and i believe they are too large allowing air into the carb making it run horribly at WOT. What size is the fuel line from the primer to the carb originally? I replaced it because when i was doing carb work I could not get the lines back on the nipples because they were too small. I had some larger line laying around and just used that.
Also what is a good way to make the small lines more plyable to be able to fit over the fittings? boiling water? heat gun?
