Poulan 2550--what's wrong with this dang thing??

[boobap]

yikes...sounds like that was a "hot seize"...not good. if it is all torn down check everything to include main seals/bearings. look for any "transfer" of metal between the piston and sleeve. you may even notice some pitting on the piston. in a hot seize, the piston expands more then the cylinder will allow, which is why it seems to run "ok" and then bog down. this is where you get the transfer normaly, because there is no lube. this happened to me once also. i was cutting a buddy's lawn (with his equipment) and come to find out that he used motor oil and not 2-stroke oil in his poulan weed whacker!!! it sucked because he was gonna give me that whacker when he moved out of town. now it is living in a dump.

Have you checked the pulse hose and pump diaphram?

Thanks for the replies..

I have not check the diaphram,
I assume it's in the carb.

Also, I'll post up some pictures of
the jug, but it doesn't look like there
was any transfer of metal.. Once it
started acting up, I shut it down pretty
quick to avoid too much damage.

Well, I got the new ring in about a week ago,
and got it back together. I installed a new plug,
some fresh gas, and it runs like new! I did what the
previous guy said, and didn't add any silicone to the
jug when I was bolting it back up.
