small engine repair


There may be crack or leak in the fuel line to the primer from the tank. If the line is leaking the suction of the primer will be sucking air from the leak instead of fuel from the tank.

small engine repair


I forgot to mention in the previous post that I did change the gas line from the tank to the carb. I didn't blow any air through the fuel outlet of the tank, but i did replace the line......should i go back and blow out the outlet? There is sufficient fuel flowing to the carb, and i didn't even think about the outlet....

I'm confused. You have good fuel flow but still no fuel to the carb?? There is something stopping your flow. Like mentioned before maybe a crack in the line but you replaced that. Blow air backwards through your feed line. This is not rocket science. Something simple is causing this. Dorf Dude...

Many small engines have either a screen, filter, or a foam block on the fuel tank end of the fuel line. If you pull the fuel line out of the tank, gently, you can inspect whatever is on the gas end for any kind of blockage.
You mention that you have sufficient fuel to the carb, but not to the primer bulb. I wonder if you have a malfunctioning check valve that is letting the primer fuel go back where it came from instead of to the engine.

Sorry for the confusion, it has me scratching my head. When I press the primer bulb, it doesn't prime the carb. However if I spray starting fluid in the carb it will crank right up and run. It does get fuel to run, but it doesn't get fuel when I try to prime it with the bulb. I changed the primer bulb, the O rings around the nozzle, the bowl gasket and the gas line.
I just remembered another rubber hose to the carb, but I do not know where it leads. It isn't the fuel line, and there was not a clamp on it. It connects to the carb much like the fuel line, but as i mentioned, it isnt the fuel line. My carb diagram don't even have that fitting showing on their drawing......

On motorcycles that rubber line your describing goes to the fuel petcock. It is vacuum operated. When the motor runs it opens to allow fuel to flow. It could be some sort of govenor but usually they are mechanicle. I still bet you have a supply problem, take the tank off and inspect the complete fuel delivery path. Your lack of fuel at the primer indicates no fuel. Get in there, you will find the problem. Dorf Dude...

Success, I got it to prime. It takes quite a bit of pressing the bulb, but it does prime and crank up now.
I took the fuel line off of the carb and put a small amount of gas in the tank. The gas ran freely from the tank, through the line to the carb, so I figured the fuel supply was ok.
Someone asked me if I have installed the air breather assembly before I tried to prime. I had not and he told me to put the assembly screws back into the carb, the metal assembly plate wasn't necessary, just the screws into the carb. One of the screws was obvious just for mounting the assembly to the carb. However the other screw held the assembly on and it must screw further into the carb and possibly block a passage for the priming circuit. I don't know exactly how, but it worked.
Something had to go bad to start with for it not to prime. When I replaced the parts, it fixed it, i just should have done more of the assembly. I learned from this and i appreciate everyones help with this....

Now you can leave the can of starting fluid alone. It can be bizarre what kind of things can affect others. I would think it could be figured out what happened in your case. The single passage that was left open with 1 screw out somewhere. The way castings are it might not even effect all machines. So in any case it does appear to be a air leak in the supply fuel circuit just not from a hose. It might be a lessen learned for more then just you. I know how it is not to put something ALL the way back together just for a test trail or run to see if it's fixed. It may have been just that kept it broken.

I have heard that the starting fluid isnt really a good thing to use, but sometimes ya gotta do what ya gotta do. I think something dried up, or cracked, or maybe split to cause the initial problem. I say that because this machine is rather new as far as hours used. One day i dragged it out of storage and thats when it decided it wasn't going to prime any longer. It set outside covered up, so maybe the carb parts dried out? Any tips on outside storage other than covering the unit from the elements?...thanks....
