Re: Poulan Woodshark

If you own or have access to a compression tester, that's the first step of troubleshooting a 2 cycle engine. It should have a bare minimum of 90 psi, most chainsaws will have power loss at 125, trouble running at 115 and most will not run at all below 100.
A quick & easy test if you don't have a compression tester is to make sure the spark plug is in tight, then pick up the saw by the starter handle. If the rope runs out quickly & smoothly, the compression is too low. If it comes out slowly and stops for a few seconds at compression, it's OK.
Other causes could be bad diaphragms, plugged carburetor, cracked fuel line, leaking seal or gasket.
