SOURCE: Poulan Farmhand chainsaw chain tightens too tight for motor to move chain

Make sure the chain is not over tightened. When adjusting the tightness, ensure there is at least 1/8" of looseness by pulling up on the chain in the middle of the bar and releasing it. If a chain becomes overheated because of leaning on the saw when the chain is dull, or lack of oil on the chain, it may expand in the track and not turn freely.

SOURCE: need true chain/bar size for my husqvarna Model 254 chainsaw

Maximum bar size of 20" but would recommend 18", if it is running sluggish, check compression, if low replace the piston, if it is 135psi or more then make sure the airfilter is clean and then tune the carb and make sure you get good revs and throttle response throughout the rev range, use the typical carb adjustments from the owners manual from the Husky web site. This is a 5hp saw and is capable of cutting some big lumps of hardwood so no excuses on the power front

i have a 4620 poulan that had the same problem. use it for 10 minutes, spend 15 minutes reinstalling the chain. i sent poulan an email threatening to sue them and they decided to send me the parts to change it over to the old style for free. try poulan.com
