I picked up several engines this summer. Most are very easy to get going. One thing I did NOTICE is one engine had a carb that when i was going to pull the fuel line off and repalce it....the little brass inlet pressed in carb was loose. I cut old line off and tapped the fitting back down in place. Be sure to support the carb correctly when you do this. I never would have noticed the brass nipple being loose...but the line was kinda stuck on it. Like RCIGN says "do not asume anything" He is right!!! Capt,n
