Update, I ordered this blockoff and was able to vac test it and it will hold pressure but vaccum is kinda weird. Vac will bleed off and I can watch oil/brake clean be sucked in, but it seems like once the liquid gets between the boot and block it seals up. Where i was able to notice it was...

https://www.ebay.com/itm/235376153309 Ok I ordered this block off tool, this should replicate the carb being installed and help narrow things down, or confuse me. Either one is likely.

I do like the idea of a block off plate I know stihl makes one and I have one for the strato saws but not the older ones for some reason, maybe I should order one.

I'm not sure I've ever heard of the magic string method for stihl intake boots but it looks like it would work. Honestly this design is why I don't tend to work on too many stihls, great saws lots of power but a PITA to work on. Also I ordered a new west boot from wolf creek saw shop and as...

Agreed, and thank everyone for all your input, the next step is replacing the boot. if that don't fix it the next thing that I'm thinking it could be is that the plastic flange that holds the boot has deformed from over tightening the carb studs. If that's the case then that requires a whole...

I have done this in the past and works really well if you have a big enough container. Only bad thing with doing this is if you have a saw that holds pressure but fails vaccum this method isnt advisable.

Could over tightening the studs cause a leak? And thank you for posting the video I hope it helps many ppl in the future.

Ok I think some ppl are getting confused here, as far as me vac testing the saw it was done by sealing off with rubber behind the muffler AND carb. This is how I found the flywheel side seal needing replaced. The issue I am having is since replacing the seal, and not related to it is, the saw...

Though honestly I haven't cut with most of my saws, CAD is BAD and time is short in supply lol.

Pressure test in which way, through the fuel inlet, or by blocking off the venturi and testing it that way some how? I've heard of ppl doing this but don't understand how it would work because of the choke and throttle. This saw starts good and revs out good, good throttle response, but I...

I somehow had a new oem seal and already swapped it in after I found the leak. But I'm still having an issue, or maybe it's not an issue, with the carb/boot area or the throttle rod. Maybe this is something that all of these saws do and I haven't been into enough of them to notice.

I'm also starting to wonder if my leak isn't the throttle rod being wore and letting air around it. I found a used carb in my pile and swapped it out just to see, surprisingly it fired right up but it is still showing the same symptoms. I haven't tried it in the wood so I don't know if this is...

The first boot in the post is the original The second one thats in the saw was the oem used one I found, it's a little smaller than the original. If you look at the back of the carb where it mates with the boot it's rough from factory, I don't know if this is causing any problems

Pretty minty looking saw I think, I haven't cleaned it up much.

Ok update: I found a used ms360 boot in my pile-o-parts cleaned it inspected for rips and put it on aaaaannnnd nothing, still same problem, and when I used the paper 034 gasket it seems to have gotten worse. I did also find a used carb in unknown condition that I could swap on but there is no...

Thanks to @GoBigBlue1984 he urged me to pressure and vac test it properly and I found a leaky flywheel seal. However now it is flooded and I can't see if it's still leaking at the carb base. So when it dries out I'll try it again. I suspect that I sucked too much oil into the bottom end during...

I did call my local dealer to order a boot and they are on backorder from stihl. Now I'm thinking aftermarket cause I'm wanting this project done at this point I've got others I want to move on to, like an echo 501p, And husky 572. What has everyone's experience with either the dukes or wolf...

When I'm looking at the boot head on it appears that impulse hole doesn't fully line up with the boot. I attempted turning the boot on the cylinder to get it more in line but the outer ring interferes some.

Hey all, I picked up a fairly mint 036 with a burnt top end. Saved the cylinder and put a new piston, fuel line and impulse hose in. Also cut the base and set squish at .020 while I was at it, cause why not 😜 . Anyways after I got it back together it fired right up I did a vac test In a can. Hit...
