does anyone have this collection of saws for science. I heard John say on the YouTube it fits but rattles. I am curious how bad the rattling is and would be interested to see a side by side comparison photo if anyone has the time?

I bought an FS70R two or three years ago. I use it to do very light work. I use it to clean up a 0.15 acre property once a week after mowing the grass. I bought it because I've always heard Stihl equipment is the best. Now, for the second time, I am having to replace the pawls in the starter cup. I am not hard on this equipment and I can't imagine what I am doing wrong. Has anyone else ever had this experience?
