Hi,

Im looking for some advice please, My 346XP was left over the summer with fuel in, and when i started it last week it wasn't as powerful and kept cutting out. I read that this could be a dirty carbureta after sitting with fuel. I have now cleaned the carbureta, careful to put the limiting screws back in the same spot, but when I put it back together I cant even get is to fire up with the choke on, let alone get it running. any advice welcome. 

 

Thanks

Celi

Thanks for quick response, this model doesnt have a primer bulb, L was one full turn out, H was 3/4 turn.

 

I was pretty certain about the gaskets and diaphrams, but will go back and double check them all. 

 

The metering arm could be wrong, is there somewhere you no of I can view the correct set up for that? 

 

Is the impulse line (thats the fuel line right?) likely to have been distrubted whilst I was doing the carbureta?

The impulse line is the small " c " shaped line that goes from the carb to the crank case . This makes use of the alternate pressure / vacuum created by the piston going up and down .

 So the metering arm was wrong, I have now set it correctly, but still having the same problem!

 

The only line going to the carbureta is the fuel line, there is the C shape line that goes to the flange on this diagram

, but I wouldn't have touched this or gone near it so my feeling is its unlikely to be the problem.

Think ADW is correct and for the record, the impulse line fits between a union on the manifold clamp and connects to the plastic surround the carb screws in to and is cock all to do with the fuel line.

Normal errors are metering arm spring fitted incorrectly and gaskets fitted in the incorrect order.

You can pressure check the carb to check the metering arm operation but suspect you don't have a pop off gauge or mityvac type pump.
