Echo 2511 won't run, fueling issue possibly

[TreeAbility]

Hi any thoughts people in this problem. 
I've changed the whole casing of my 2511 as it got dropped and broken. 
Had to strip pretty much everything off and put it back together. 
It ran once briefly but now won't run. There doesn't look to be any fuel getting to the spark plug. I don't think the pipes are pinched but there's nothing coming out of the fuel pipe from the pump Prime bulb. The other pipe has plenty of fuel coming out and there's fuel in the rubber bulb when you pump it. 
Should there be fuel coming from this short pipe? Could the New bulb be faulty??? 
 

Any help or thoughts appreciated. The pic is the old broken case BTW not the new one!

You need Spud @spudulike

Sod off, I once had one of these in and after pissing around with it, getting it running and it flooding etc etc, I realised someone had cocked around with the fuel pipes and had to work out what they were doing and what they should be doing. 

It transpired that the owner had swapped them all around when he tried to "fix" it!!!!

All you have to do is connect the pipe connected to the fuel filter, to the PUMP part of the carb and the other one needs to go to the bulb and then return to the tank. 

Basically, the bulb draws the fuel from the tank through the carb and then returns it to the tank if my memory serves me right. 

Next time...take a photo before stripping it!!

Great, thanks Spud. I think the problem may be in the carb then as the pipes are all correct. I did photo it all and it seemed OK. It ran briefly then stopped and won't run at all now. Got a tiny fire from it after repeated pulls on the starter. Compression seems fine. Have checked the spark and changed plugs as well. Stumped now 🤦‍♂️ and not confident to pull apart the carb apart from checking the gauze which was clean.

Spud is quite correct ref the flow of the fuel, you have to remember it’s a purge, not a primer, put round the wrong way and a couple of pumps will flood the engine, note the two pipes on the purge bulb, the short connection will be the suction side so goes to the metering side of the carb, the longer connection is the pressure side goes back to the tank, the fuel hose from the tank goes to the the pump side of the carb, then as Spud said the fuel is pulled from the tank to the purge bulb via the carb, and from the bulb back the the tank, this allows you to pump as much as you like without flooding the engine.

Did you remove the flywheel at any time? if so has it sheared the flywheel key?

Yes did take off the flywheel but the key was fine and put it back in correctly. 

Fuel isn't getting to the spark plug, it's dry when I check or just slightly damp once after I'd done about 20 pumps on the bulb.

Pipes all seem OK, the bulb is pulling the fuel through fine (now I know which direction and what pipe does what 🤣)

Very frustrating 🤯

So I guess you have a huge air leak, or you have no impulse for some reason.

Air leak could be possible. I've got anither 2511 with Artur at the moment and that's got a leak in the carburetor manifold. Not sure what bit that is though! 

My saw did run briefly but I'd not done the clutch up tight enough, it came loose, I did it up again but now no joy 😔

If your fuel pipes are all on the right way around, the intake manifold is fitted correctly and isnt split then it could be the little white plastic insert is missing from the intake manifold. It is this piece

It keeps the impulse hole open, which is what operates the fuel pump inside the carb.

If you are giving it a good pull over with the choke on and the plug is bone dry you need to check those parts and and maybe strip the carb. Just check the fuel pipe from the primer bulb to the carb isnt pinched i.e routed the wrong way.
