KEEPS DIEING ON ME

[TSHAWVER]

I HAVE A M151A2 IT STARTS AND IDLES FOR 10 MINS AND DIES, FUNS GOOD DOWN THE ROAD BUT WHEN I LET OFF ACCELERATOR IT DIES, I'VE PUT A NEW CARB KIT, CLEANED FUEL LINES, CHECK THE SPARK PKUGS FOR FIRE, REPLACED FUEL FILTERS, ANY SUGESTIONS OF WHAT ELSE COULD BE CAUSING IT TO DO THIS

[raymond]

When it dies, does it have to cool off for a while before it starts, if so, I would suspect the coil.

[TSHAWVER]

NO IT DOESNT HAVE TO COOL OFF TO RESTART, BUT I HAVE TO HOLD THE ACCRLERATOR DOWN HAVE WAY TO GET IT TO START THEN HAVE TO KEEP THE ACCELERATOR DOWN AT A HIGH RMP TO KEEP IT RUNNING. IT WONT STAY RUNNING AFTER WARMED UP.

Use a clear fuel filter before the carb. This way, you will be able to see if you have rust/dirt in your fuel system. See filter inside white circle in picture:

I bet Mr. Carb, i.e. Rickf will have a solution to your problem.

I don't want to leave you hanging but I have to get to bed and I have three or four things for you to check. I will get back to you in the morning.

OK, Check to make sure the vent line to the tank is not clogged. Put a clear filter in the line before the carburetor and see if you are getting any air bubbles, if you are then the fuel pump is bad or you have a leak in the line before the pump. I would also check for vacuum leaks around the intake manifold and it almost sounds like maybe your valves may be set too tight.
This could be a lot of things so check in the order I gave you since that is most likely to least likely. It sounds most like a fuel delivery issue and the fact that it takes a while to come on makes me think it is heat related or clogged vent building vacuum in the tank. When it does it open the gas cap and listen for a "hiss".
