Don't think so, but unsure, New gaskets/seals, air intake boot looked good,  Where should I check or is there a way to find out for sure?

Rechecked jug bolts, needed to be  re-torqued.  I should have known better, after it cooled the first time to recheck them.   Problem solved, runs and sounds great.  Will re-post after 3-4 hrs break in period.   This site and you guys are the best!!!!  Thanks again for all your help with this project I can't wait for my daughter to get home today and hear it run.

Around the base of the cylinder because the bolts were not tight.

Ok,  saw is running great, went to top off tank and fuel was leaking out.  Pulled tank off and it seems to be leaking from a factory hole that has a "rubber??" type hose or line inside.  if I blow air into this, fuel shoots out the fuel line.  On the IPL page it looks like a bolt or a needle type valve might go into it.   I know I didn't remove it, but I'm unsure if it's missing a part.  Thanks

On second look of the IPL, it looks like # 537 09 22-01 is some sort of bolt or shaft, with 537 09 93-01 one way valve or filter????  HELP!

I think this is what I'm missing, but not sure..

I don't know what year your chainsaw is but the tank vent was changed in 2007.

Before 2007 they had the black plastic stand pipe vent 501 87 31-01 with a little disk of cork or felt 503 60 04-01 stuck in the hole

In 2007 there was a 90 degree fitting 537 09 22-01 went in the hole of the stand pipe 537 09 22-01. Then in 2011 with a rubber hose 544 32 49-06 connected to the elbow fitting went up through a hole into the carburetor air box 503 62 73-03 in a loop and connected to a little spud in the air box floor that vented the tank to the area between the carburetor air box floor and the gas tank.
