thanks very intersting
the way you put your wrist pin circlip on was very intersting and easy, watched few videos , never saw anybody do it that way.

[@MowerMike]

Glad it helped. FYI I never got that saw to run right again. So do this at your own risk.

Nice job Mike.Very interesting.

[@MowerMike]

Thanks 👍

[@robstillman2133]

Mike. Great video. Like you I usually just dive right in. I think my 450 has an air leak problem at the crank so will do a tear down like yours. Did you have a link to the 450 shop manual? I didn’t see it in the description.

[@MowerMike]

Nah just google it. I think the husqvarna website had some good links to service manuals.

[@robstillman2133]

@@MowerMike definitely an air leak confirmed by spraying carb cleaner down by the crank on the clutch side. Waiting on the seals to re install everything. Thank you!

Did it start?!?

[@MowerMike]

It did but it only idles. Am still working on it. I think it is just a fuel issue now. Has a ton of compression. Thanks for watching

[@Batman-mp4mx]

Thanks for the video. I have the same chainsaw and need to replace the oil tank which requires the full break down like you did. If you get it running good I'd like to know what the fuel issue is.

YOU MAY HAVE a PROBLEM !!!!!
When you remove the magneto (finned wheel) to the left bottom at7:30ish,there is a brass colored piece !!!!!! IT IS a GROUND!!
Hope it’s there !!

[@MowerMike]

I have no idea. I gave up on this thing. It never did run right again.

[@terryherrera5252]

GREAT JOB !! Like many of us !! Dive IN n hit er done !!!!

[@CodyHoggatt]

What year is this saw?

[@MowerMike]

No idea it is long gone

[@welshwizard822]

So painful to watch, so I couldn't. Man but stick to mowers 😢

[@MowerMike]

I know I know, these dang chainsaws are just so fun.
