Mcculloch hedge trimmer when I put it on its side to fill it up petrol pours from the opposite side does the tank have a breather

The fuel line hook up is wrong. Ok, so look at the two nappies on back of the bulb assy. The long nipple is for the fuel return line, (the line without the fuel filter that returns to the tank) the short nipple , that line goes to the fuel barb on the carburetor, on the same side as the bulb assy.. then on the opposite side of the carburetor find the fuel barb, connect the fuel line to that barb and into the tank where the fuel filter is on the end of that,... If you have trouble understanding what I mean, hmu.

Agnes take of the cutting head again and see if it runs at full speed without it. If it does you have either put the head on too tight or it's the wrong head.

What is the spark plug gap on the tivoli 60 hedge cutter?

could be the air filter needs replacing

Most newer 2 stroke engines run on 1 part oil to 50 parts gas.
Use a high quality 2 stroke oil mixed into the gas.

The specified ratio is 40:1
40 parts gas, 1 part oil.

The problem was with a stripped gear on a mcculloch hedge trimmer. I chucked it on the scrap heap and am borrowing my father-in-law's machine until I have time to shop for a new trimmer. Problem solved, but sadly not owing to your service this time.

There should be a strainer on the fuel intake line in the fuel tank. Take it out and clean or replace it, and check the fuel lines for cracks or leaks. If this doesn't fix it, disassemble and clean the primer button. There should be a little one way flap valve that opens to allow fuel to be sucked in from the fuel tank and closes to push the fuel into the carburetor.
