Husqvarna 365 cylinder & piston on a 353?

[Not_Husky]

A kid in Australia rebuilt a 353 with a 365 slug & jug. It ran. There's a YouTube video showing him do it. I was surprised, because the 353 stroke is 4mm shorter than a 365. So I asked Google "WTH?" The AI reply is below. Anyone else try to mate the two? Any opinion on how it would run? It cut through a 14"-ish log but a lot slower than a 353.


A 365 Husqvarna cylinder piston kit can fit a Husqvarna 353 chainsaw, but you may need to make some adjustments:

• Cylinder gasket
  The cylinder gasket in the kit may be thinner than the original equipment manufacturer (OEM) gasket, and the bolt holes may not line up. You can try trimming the gasket with an X-acto knife after high tacking it to the cylinder.
• Intake port
  The intake port in the kit may be 0.015 in smaller than the OEM port. You can try using Permatex Right Stuff to fill the gap and then apply the clamp. You can also buy an aftermarket manifold that uses a worm drive hose clamp.
• Exhaust gasket
  The exhaust gasket in the kit may not be made from a high temperature material.
  
  

The Husqvarna 353 is a lightweight, professional chainsaw with a 20 in bar and 3.1 HP. It has wide-set handles for balance and maneuverability. The saw uses a 50:1 fuel oil ratio.
