Spuds Porting and Tuning Thread

[spudulike]

Well, here it is at long last. Some of the guys on my other "Whats on your Bench" thread aren't in to porting so thought I should split out this type of chainsaw modification for those with similar interests.

 

Personally, I got fed up with just repairs and did a blokes "I wonder what would happen if....":001_rolleyes:

 

I purchased three 346XPs, two were for resale and the third......got ported and I never looked back - the results of the porting sounded and felt great so the porting bug stuck.

 

Currently I am working on an old 066 that will be a real beast once done but that will appear soon.

 

Today it has been MS441 tuning, the ring end runs down the side of the exhaust port messing up any chance of widening it unless you want a lop sided port and uneven blowdown:thumbdown:

 

The saw is a strato so left the porting and recommended just a simple muffler mod - I had two diameter pipes I could have used, a simple hole would have a similar effect but like to make the finished job look good so chose the smaller of the two.

 

Good thing I did as it is suitably loud. I also openend up the existing hole. Pickup is faster now and am happy with the look:thumbup:

 

So Gents, a start of what will hopefully be another great thread:thumbup:

Tidy job on the muffler Spud , I'd love to get you to have a go at my old 066 .

[spudulike]

Well, the one I have is an old red eye that blew its ignition module - I need to re-key the flywheel but apart from that, the ports will be opened up and the blowdown altered.

 

A local guy I know has a lathe so a pop up piston and turned down cylinder should up the compression to nearer 200psi, I am currently cleaning and re-spraying it as it is ratty but mechaincally good.

 

I will be doing this as time allows:thumbup:

I stuck a duel port muffler on my 066 , took the mesh spark shield out , sounds good but I'm not sure it runs any better !

3 of my saws have been ported by Steve with another on the way shortly . Maybe it will feature ........

Good thread to start Spud.

Ported an ms260 today but all back together again now except for the muffler which I need to mod with a piped outlet when I get chance.

Had to stop work to make a start on the roast..... (bloody missus saying she would do a 12hr shift on a sunday!!)
