Default Re: Vapor Lock 101 ?

Today in a friends car here in Denver ,air temp 101 degrees,5280 feet,same stock up draft Zenith,car started to run rough,opend GAV and it helped a little.Enough to get it off the road,We cracked the gas line and air came out.Gas could be heard boiling in the carb.After relieving the air lock and a cold wet rag on the carb it ran fine until it heated back up and the same happened again.Took it out for a ride tonight at 80 degrees no problem and ran great for 25 miles.Call it what you like but it seems like vapor lock to me.Phil
