Just to update this thread, I bought one of those face shields like the one in the 1st picture; the Pyramex. I've had it a couple of days now and tried it out on two jobs using my string trimmer. I made sure that the shield was touching my chest so that I had full coverage. I'm getting stung in...

I was thinking maybe some of them might be a plastic mesh like they have in some oil filters.

Do you guys wear safety glasses under the wire mesh; or don't you think the wire mesh protects you good enough by itself?

They're supposed to be real good at protecting you while using a chainsaw, but I'd be using while using my string trimmer. The wire mesh seems like it would resist fogging up in the cold weather brilliantly. I currently use a NoCry clear plastic face shield and let me tell you, it has saved my...

The trimmer has never ran better since I installed that NGK with the .025" gap. I used to have kind of an uneven idle speed. Now it's rock steady. Very pleased.

Fantastic. Thank you sir for the quick answer.

The middle intake gasket is the place I found a leak one day. Carb spray over the area would kill the engine.

I bought an NGK CMR4H. NGK says they recommend the gap to be .028". STIHL says it should be .020". The actual gap I measured with a feeler leaf is .025". Can I leave it at .025" or should I squeeze is down to .020" ? This is for my STIHL FS 91 R string trimmer which I consider to be a hero...

I hate cylinder de-activation and variable cam timing.

I love these Bondhus Torx drivers. Very comfy.

On a cold start the rope is easy to pull. When the trimmer gets hot after running for so long, the rope is harder to pull. Is this the beginning of the valves needing adjusting?

Some guys are kinda dense. 😁

Just to update this thread, I found out that the limiter cap is on an air bleed valve, not an idle jet. That's why there's not much of an idle performance difference by changing the position of the valve. The idle will actually get worse by changing the position too far. If I'm ever going to fix...

I have one. The first generation swivel cuff used to pop out of joint. They have since came out with an upgraded version. The unit still has a very stiff corrugated elbow that is cumbersome to move around. The runtime is only about 40 minutes on wide open throttle. Most of the time it sits in...
