chainsaw not firing up

[Topcat]

Back to the days of the FTC (forestry traing council) so here goes. There should be 3 Screws,T,H and L.The first thing to do is turn in the T screw (tick over). Then turn both the other screws fully in. Turn both the L & H screws out 1 turn. That should start any saw that has fuel and a spark. On tick over turn out the L screw until the engine peaks, then turn back 1/4 turn. Rev the saw to full belt and turn out the H screw.When the engine peaks turn back 1/4 turn. All you need to do now is set the T screw to idle speed,IE the saw runs but the chain does not move.You may need to tighten the chain. GOOD LUCK
