Small engine valve seat
The engine on my leaf vac wouldn't start & I diagnosed low compression.
It's a 5HP B&S. Here's a picture of the exhaust valve seat (after lapping): http://home.comcast.net/~bobengelhardt/ValveSeat.jpg Does it (the seat) need to be replaced? The B&S Repair Manual says that after replacing a seat, it needs to be cut. How important is the cutting? I'm not about to buy a cutter & I'll take the engine to a repairman instead. Thanks, Bob |
