@6620, This is an excellent overview of what you can do yourself. If you were near me, I'd offer to help, but I bet you're not. Notice the spun wire cleaners in my Avatar which is the little picture above my name to the left of each of my posts. That's what I use to clean jets in carbs. Based on some discussion, it appears you have a fuel pump instead of a carb. I have no experience with pumps, so you're on your own there. Good luck and remember: there is ALWAYS a reason, you just have to discover it. That is the task.Start at the basics. Air, fuel, spark and compression.
1.Air = remove air filter FOR TESTING ONLY.
2.Fuel = remove fuel line AT carb. Pour into a glass jar. Start engine if you have an fuel pump or let gravity do it's thing. Should have good fuel flow AT carb.
Clean carb. Might take 3 cleans till she works proper. Stay away from ebay/amazon chinese carbs. Or replace carb with OEM.
Check for vacuum leaks. Spray WD-40 around carb mount and intake manifold areas. If the engine smooths out, you found your leak.
3.Spark = take an old plug. Gap to 1/4" wide. Ground on engine block. Should have a nice blue spark.
4.Compression = use a gauge and see what you have.
Have you ever pulled the metal engine shroud and cleaned the top of the block and cooling fins? This is a yearly maintenance item in ALL engine manuals. Neglect this and you are looking at engine damage. I know, what cooling fins.
There is ALWAYS a reason. ALWAYS.
