Make sure the clunk line from the tank is on the carb... I've seen LOT's of people struggle starting an engine because of reversed tank lines... never happened to me either Make sure the HS needle is OPEN... A good friend that's been in the hobby for probably 40 years about 20 years longer than me was having no luck starting his 91 FS... I was being a smart ***** when I asked if the HS needle was closed off... turns out it was I also find putting my finger over the muffler stinger is a better way to choke the engine and make it draw fuel faster.
