echo heats up?

[cjrenegade82]

i have an echo cs520 that gets real hot when i run it and im not sure y
im running the carb a little rich because of that didnt help much
useing echo 2cycle 50 to 1 poulan bar oil as much as i can get on there so i still run out of gas first i tryed a heavier oil echo and stihl didnt notice a differance the chain brake dosent seem to be dragging the clutch could be slipping not sure how to tell if its not real bad but the saw is a year old not to much use 50hrs or so i clean everything off blow any dust out of it after every use. spark plug looks good gapped to spec clean air filter gease spocket often
chains are sharp stock saw except no screen in exhaust. saw is now running at 12000 rpms after carb adjust iv been cutting mixed hardwoods
maybe this saw just runs hot i dont know but is too hot for my liking
any thoughts would be much appreciated thanks

My 520 is running 13,000 with the screen in the muffler, 20" bar and chain.

It gets hot too...but it runs great.

How are you judging the temp, and what are you comparing it to? Modern 2 strokes get hot, the fan blows the hot air off to the clutch side...same as the muffler.

im comparing it to other saws iv used stihl husky poulan and this seems to get much hotter and stretch chains out often
