21cc Poulan spring muffler 17x5 zinger @ 6900 and weighed 32oz on gas glow

my buddies 21cc was more powerful turning a 17x6 APC at 7200.

Yep my 21cc indeed did turn the APC 17x6 @7200 on gas/glow and did weigh 32oz but my 21cc was the one with the extra long shaft, not the stubby one, i think it was about 11 years old.

I had a featherlite 21 I found in the trash at the side of the road.

It turned a 14-10 at 7000 with a Homelite 25 carb and opened up exhaust. I gave it away
