Hello. STIHL Canada doesn't list either the 510 or the 760, it seems to be a STIHL USA item (??)Here is the link for the manual. It is about 1/3 of the way down the page listed under the heading " Construction Tools ", on the right hand side.

Let me know if this helped out.

There could be a few problems. Check the air filters and make sure that no holes are present in them. Then check to make sure the unit has compression. A general check of the compression for a Stihl unit is to hold the unit up by the rope and it should hold itself up. If it slips down really quick or if it does not hold itself for more than a couple of seconds before the rope starts coming out, then the unit is low on compression and will need a new piston and cylinder.
Also another thing to check is the carburetor. With the new fuel with ethanol/methanol in it, it can damage parts in the carburetor. The sealant that went over the welch plugs will come off and it will flood the unit out because there is no regulation of the fuel going into the engine. You can try putting new sealant, such as clear fingernail polish over them, and see if it holds and will regulate the fuel correctly. If the air filters have holes in them then the low compression could be caused from dirt ingestion and it could have caused wear on the main bearings. You can check for bearing wear by seeing if the flywheel or the clutch will move up and down and sided to side. If this is the case then you will need to purchase a new unit.

Hope this helped.

This is not difficult. The impulse hose as it is called presses on to a brass fitting under the intake manifold. remover the filter housing, filter, carburetor, and tank as needed to make room to get in and replace it. Parts can be ordered from you local dealer like www.arcolawn.com

Hope it helps
