How do you figure that mate? My 2 oldest saws are ported.

Simple physics.

If you squeeze the pips from small engines they will die quicker.

You’ve had good luck, and I know you look after your saws really well, which obviously helps.  

 

Same with trucks really.

None of these modern 1.9’s tweaked to 240hp will see 300k miles like the 3.0l donks.

I disagree, as long as the porting work is done within the tolerances of what the saw can handle there's no reason why they shouldn't last as long if not longer.

 

Most saws are restricted by noise/ emissions. It's amazing what you can get out of them if you're not bothered by any of that.

This was my understanding as well.

 

I don’t want a ported saw mind, I like hearing things too much.

Plus in domestic arb they’re not necessary and I think the insane noise alienates clients and walk by potential clients.

 

As Mark says, sharpening is a discipline worth practicing.

I get the analogy Mark re the truck engines but its not quite like that with the ported saws I have . Manufacturing tolerances dictate that the design intent can not be optimised due to cost . If Husqvarna could make all saws like they are when Spud has finished with them for the same cost I'm sure they would .  The saws spud did for me don't over rev . They get up to max revs quicker and hold torque in the cut stronger . They in effect run more efficiently ( also cooler ) so actually under strain less . This I feel makes them last longer . Just my take matey .

You and Joe are almost certainly right, but like Mick I’ve never felt the need to have my sharp saws cut faster.

It’s not the choke point on a job.

 

A lad turned up one day with a ported 462 with a bark box and just pissed everyone off all day with the noise.

 

Did we finish the job any quicker?

No.

Yeah i agree about the bark box. A mate put one on his 500i and it may as well have had an ASBO.

 

The 3 that I have (2 now the 200t is beyond economical repair) sound a bit lively but aren't noticeably louder than stock. They pick up way faster though.

Sorry matey.

 

I wondered why I never got anymore work off you!

The more open muffler and greater flow reduces heat faster and lowers the chance of seizing due to excessive heat so the ported saw runs cooler.

The bark box is a prime example of poor modification IMO (I have had the unfortunate experience to have heard a few), I always bounced the exhaust port shock wave off a muffler surface before exiting the muffler, that way you still get decent flow but also don't increase the noise excessively.

I preferred what I called "a rorty exhaust note" to "ear bleedingly loud", the ported saws I did were generally used in domestic and commercial work and any modification should be sympathetic to this use unless the customer states "forestry only" where decent ear muffs were needed.

I'm still gutted I've had to retire the 200t you did for me. I could buy a new crank case and rebuild but I'm loathe to when you can't get an OEM pot any more

[spudulike]

Yup, big shame on the OEM top ends being phased out. The last MS200T I did I used an 020T top end but must have been one of the last available as they are not listed now.
