If you have an air leak near the right crank seal, the saw was probably run hot with a dull chain and the right side of the case deformed. I picked up a rebuilt 350 and it was done wrong. I tore it down, ported it, and it leaked. Tore it down again, used more sealer, and it leaked again in the same spot, as pictured in this video. I ordered a new case and will be putting it together soon. I can see where the old case is warped and can see the impression of the seal in the plastic. Hope this helps.

You did a good job how to check a air leak on a 2 cycle chainsaw thank for your input.

Enjoyed watching your latest video on the chain saw. Was very informative great job.

You can also take the seal out and put a new one in clean up the area very good and use ultra gray around the outside edge to help seal the outside walls It will help feel any imperfections ๐๐ป๐ค๐

Use a old toothbrush handle, you can put a slint bend in it if you want to, works great as a piston stop

yep, common place to leak. i put 1191 around that seal when i put the crank in my 345. Good video. i suspect i have a leak in my stihl 361 (kit from parts farmertech i put together. Do i need a carb plate to seal off the intake?

Husqvarna 440 x torq is there a compression check it was 35 I put a new cylinder and piston kit I put it back together I didnโt have a compression check and it was the same I was wondering if it could be the seals cause I wonโt even start how much compression should have

What do you have to do to fix that leak right there that's what you need to tell change the seal or use a sealant for the crankshaft seal

What brand is your pressure/vacuum gun? Where did you get it?

Thanks for sharing ๐๐

I think my Echo CS-400 has a bad air leak. It idles at half throttle in spite of all tuning. It has a new carb and new fuel hoses and tank filter. It about has to be the crank seals. I like the innertube to block the exhaust and intake. Inter tubes are high now just like everything else. I wouldn't have thought it would leak around the outside of the crank seal but there it is. Do you recommend any type of sealant around the crank seals?
