Miller Mod Saws and the CS-500P Echo!

[Mastermind]

What carb is on this saw?

What is the venturi diameter?

Carl or Randy, are either of you willing to measure the intake boot and spigot on the cylinder? Dimensions would be helpful for guys looking for a work-around.

I'll have the carb off again. I'll measure it......

 

[Miller Mod Saws]

13.5 is the venturi size. And the ID of the metal ring is 16mm.

Repped.

What do you think about taking the head of the plate screws down some?

I'm machining some other stuff now.

Let me tell u in just a bit. I ground the heads of a little flatter and shortened the bolts just a tad so when they went threw the we're flush I stead of hanging out. Headed back out to get me a load of wood before the big snow storm hits. Lol.

The 500P and 044 10 pin will be humping for me the rest of the day!

 

[Miller Mod Saws]

O will tell ya I'm chicken to bore the venturi as I did one and while it ran good at wot. It made it funky to start and jacked with the low end! I guess where I'm going with this is not what I want in a work saw.

I call my gig Mastermind Worksaws.

I'm never gonna be Mastermind Racesaws

Ok boys I couldn't tell a big difference if there was thinning the carb screws but that said it she dosnt hurt.

I just got back in from the woods so stay tuned for my opinions. Gonna cook some supper than well talk. We put 4 tanks threw saw 2 and 3 threw saw 1.

You got right after it!!!!

And as you can see especially saw 1 isn't lacking in torque. That's hedge and the hardest wood to cut in my neck of the woods!

Didn't look like either one had too much trouble turning the ground yellow. Hedge is always fun to cut.

Alright. Here we go. The epoxied intake saw was still holding it's rpm just a little better at the end if the day. But that said. I think for a work saw!!

Having the exhaust at 108 with around 15 degrees blowdown and leaving the intake alone is gonna make anyone smile.

The epoxied intake well it maybe awesome if you wanna find a bigger venturi carb. But these are fine runners and I wanna recap the trans. There not fun at all. Lol.

Thank you Randy for going threw all this with me. It was fun!

I have a 600P on the bench now. Have you done one of them yet?

No sir! Love to hear about it though!

 

[Mastermind]

I'll take some pics and stuff. But not tonight.

Good thread, I really liked following along. I ran Matts 500p today, and one things for sure, it would be hard to go backwards peformance wise.

The 600s bore is only 1mm larger, at 45mm. Be careful cutting the squish band or piston, they freeport real easy. Its a good thing they have decent compression stock.

 

[Four Paws]

I like the 600p piston!

 

[awol]

What was it you put the 600 piston in?

 

[Four Paws]

This saw needs more carb......I can't get past 13,500 or so on RPM.

For the sake of discussion, do you think the short blowdown is holding the saw back from higher rpm?

Do you feel moving the exhaust up to 104 and leaving the transfers at 124 would allow the saw to turn up a bit more?

Shindaiwa 575.

That single ring sure gives a guy room to work.

Not sure really Josh. I'm afraid to take the exhaust higher. Might cut out.
