Chainsaw Repair

Good thought Saul! The 181 did use an internal pulse through the manifold. Could be a misplaced or mis aligned gasket. Or the face of the manifold could be clogged! Looks like he should take it apart again! May even be that the passage through the cylinder is partially blocked. We all know how much goo gets clustered around the intake tract on an older saw! However that would require removing the cylinder to clean out the cylinder port.
