Question about Husqvarna Garden

Open Question

I paid 160.00 for a husqvarna 257.It has compression of 120.It nedds to be 140.Would it be worth it financially to have the top end rebuilt?I was also wondering if I am somewhat mechanically inclined,would it be difficult to rebuild it myself.I definitely don't want to make it worse so should I just leave it to the professionals?

Cracked head or blown head gasket. This is a result of coolant or water mixing with the oil. There may also be signs of this in the coolant in the radiator

You may have a problem with your reeds.If you have done a rebuild because something internally has destroyed itself then the chances of those loose metal fragments chipping or cracking a reed are quite high.Pull the reed block and check it out and replace if neccesary.Other than that i can only presume a problem with the rebuild.hope i've given you some direction Armstrong.....Good luck with it .

What is the compression on a poulan pro

120 to 140 is ideal. Less than 100 its probably not worth repair. Less than 90 it wont run. Those blowers are notorious for the cylinder coming loose. Be sure the 4 cylinder bolts are tight before checking the compression.

I have a husqvarna 350 that wont start, wondering if anyone can tell me what is the factory compression rating?

Hi and welcome to FixYa, I am Kelly You should have 120 PSI or greater compression. There is a ported compression release so you may see as little as 110 PSI but it is best to see 120 or greater.

The Owners manual is here:

carb basic settings are on page 29 of the manual.

The saw has a Zama C3-EL18 carb.
The manual for the carb is here: (Click and wait 2.50 mb)
Your carb is the C3

The workshop manual for the saw is here: (Must have a facebook account to download but can be viewed online)

Thanks for choosing FixYa,

My husqvarna 359 chainsaw blows fuel out the exhaust when I try to start it. Just rebuilt the carburetor with a kit. Still same problem.

You need a carburetor kit. The needle valve in the car. is stuck open. The needle valve helps to control the flow of fuel.

Hard starting and when warms up rpm's drop

Remove the muffler and inspect the piston, rings and cylinder for vertical scoring. If so You may need a top end rebuild.

Piston ring

The piston ring whilst the piston is still in the pot should be relitivly tight. This is because it creates the seal to maintain compression. When the ring is taken off the piston it only has about 4mm gap between the two ends, any more than this it's probaby knackered. worth checking pot and piston for scoring around the exhaust outlet as if it's going to loose compression it will be at this point. If all these are fine check the decompression valve (if you model has one) if this is broken your compression will be ruined.
