Took the 421 in yesterday for a tune up. On a recommendation, I took it to a local small engine guy. Here's what he did...
1. Change Oil & Filter
2. Adjust Valves
3. Inspect plugs and wires (I had just changed plugs)
4. Removed and cleaned carb
$85 out the door.
I thought it was a bargain. I've never had the valves adjusted before, but man, did it make a difference. Thing runs so much better than before.
I've read threads before about having your valves adjusted, but never really gave much thought to it. Live and learn.
