The later 353's had the bigger bore too.

Tell me more on this subject and comparison of tops pistons etc..

I'm getting 350's mixed up with 353's!!!! my problem is that I own a 45mm 350 and do not own a 353.

In the 350's there was the early and late 44mm bore and 45mm bore and I know the 45mm has a dished piston. These are plastic body saws with a clamshell engine. But there is an adapter piece in the clamshell so they use the same cylinder as the 351 or 353. The 345 was a pure clamshell engine piece.

All the 353's are 45mm flat top.

Before the 353 there was the 351 that was 44mm

There needs to be clarification as to which of these cylinders had the removable transfer covers as I know the 350 45mm bore did? I also know that neither of the 346 cylinders had removable transfer covers.

Where do yo guys get your aftermarket parts for something like this, and who makes decent ones?

There's a significant variation in quality amongst the after market parts. Even one person reporting how good his part is from one company, then you buy the same part from the same company and it has to be massaged before it will work.

I bought a operator presence throttle lever for a Husqvarna 372. It was of a familiar after market brand. I had to sand the width down and then file the latch part where it interfaces with the trigger to get it operating smoothly and not hanging up.

The other day, I was looking at a big bore piston that was in one of my 372's for a short while. Upon close examination, there had been a problem with the bevels on the edges of the ports in the cylinder. Specifically, looking at the piston wear patterns, there was a problem on the cylinder with the shape and bevel along the top of the exhaust port and the vertical sides of the intake transfers towards the exhaust ports. The piston was removed/replaced with a Meteor piston made for a 064 and the cylinder was ported so most of the problem was eliminated?

Meteor brand pistons and Caber rings are well respected after market brands. Yet cut4fun and I were comparing a Meteor piston for a Poulan with the OEM piston and noticing little differences here and there.

Thanks.  The variability in the aftermarket parts has me wondering if he'd be better off going with OEM, especially since this is his first time digging in to a chainsaw.

The 44mm top ends, 351, 2149 and early 350/2150 were a straight open port design, with no removable covers. 353/2152 and later 350/2150 all had the 45mm top ends with the removable covers. As aleready stated, plastic case models had a dished piston and the metal cased saws had the flat top. 346 jugs never had removable covers.

For guys porting, the 45mm jugs offer more potential gains. But staying stock, the 44mm set up responds real good to a muff mod and compression bump by replacing the gasket. It's a strong runner that will surprise ya!
