I got my 51 3100 with 216 out on the road for the first time and it ran fine then sputtered and quit. I put a clear inline filter up near the carb and it was empty. I went home for gas and when I got back I put some in tank and primed the carb. As soon as it turned over it started pumping gas thru the filter, it cranked ahile then started, I made it a half mile and it quit again, filter was empty again. I noticed the intake below carb was very hot,and the carb base was cold and sweating. Pump is new, and I have the vacuum line to wipers pluged, sprayed carb cleaner when running and no vacuum leaks. What do you guys think? | | | | | Joined: Jan 2005 Posts: 394 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 394 | Did you clean your tank out at all, may have some stuff floating around that blocked the flow, happened to me, undo the line from the tank and see what comes out, have a big container to catch it. It will be messy | | | | | Joined: Mar 2008 Posts: 29 Apprentice | | Apprentice Joined: Mar 2008 Posts: 29 | I had the tank out cleaned it and sealed it. I can check just to make sure. | | | | | Joined: Mar 2008 Posts: 29 Apprentice | | Apprentice Joined: Mar 2008 Posts: 29 | Gas flows freely from the tank but for some reason I didn't have the valve all the way open. I am not going to put it back on the road until I have insurance, I just couldn't resist a little ride today. | | | | | Joined: Jan 2005 Posts: 394 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 394 | at least you know that part is good. I'm sure that you blew out the lines also, good luck and happy driving when you have it on the road. See you are from WI. have a few relatives up in Fox Lake have not been out to see them in years.

Never heard of Fox Lake, We are way up North.

Even with the valve partially closed the filter should have some gas in it.
