Echo 501P. Let's play!

[Miller Mod Saws]

Where does the comp end up on these?

Saw 2 is up round 108 exhaust.

I'm getting ready to check but I did a quick check and they were north off 200.

 

[RI Chevy]

Wow. Ok. Looked a little longer on saw 2.
Excuse me please. Lol

I'd be curious to run one of yours and Dad's muffler modded MS261 back to back in cuts like that and see just how different they ran from a feel perspective. Bang for the buck, that might be near unbeatable. I'll always be partial to the 346xp and the 550xp is quickly growing on me, but that's a hell of a deal at that rate! I may steer a good friend in that direction as that may end up being all of the saw he'd need (once ported) and the un-ported break-in time would be an ample learning opportunity for him to develop skills and knowledge before turning up the wick.

Well both of these will be for sale when I'm done. Now that said. The little echo is a nice little saw. I like them all. Lol. Each and everyone one of theses pro grade 50cc saws has its advantages and disadvantages.

 

[Miller Mod Saws]

I need to get some serious run time on these 2 before I proceed. I think saw 2 will come around but needs more fuel. The 500P seemed to take about 4-5 tanks to come around.

It is funny how some saws take longer then others.

 

[Red97]

I sold my ported 346, because of a ported 490. Quit using the 261c cause I ported the 346...

Think the 501 will be a bit ahead of the 490 once worked over..

 

[Miller Mod Saws]

@Red97 this is after tank 1 in saw 2. Lol.

 

[RI Chevy]

Wow!

 

[Nitehawk55]

I might have to get you to do my new 501 but I would want the compression around 200 .

I would have to looking into upgrading my man card to be able to start that. All my friends would laugh at me if I couldn't start my 50cc saw when it is 0deg out.

 

[Sam_choq]

Hello budys can anyone tell me , what is the differens between the 501p coil and the 500p coil ?

 

[Miller Mod Saws]

There's no squish band work done to these saws. Only the squish set.

 

[Miller Mod Saws]

I have start a compagnie in november and for this i bought a 501p , so now i have put arround 400 hour on this saw . Very nice little saw very economic on gasoline . But i notice some probleme with the new starter in winter comparatively to the 500p starter If i want to use the saw in snow i have to run it with the 500p starter...... And i broke the coil because of a impact , i want to know what the difference is if i put a coil of an old 500p into my 501p

This is a question for @WSE15 or @fordf150. I've had no issues with the recoil on either saw. But these are the only 2 I've played with. Let's see what they have to say.

 

[Miller Mod Saws]

Ok guys I wanna give ya my opinion. I got both saws broke in and going. The saws cut neck and neck with each other. The 110 saw would hold its rpm better the 108 saw was snappier and limbed better.

 

[Miller Mod Saws]

So I tore the 108 saw apart and went 107/124-127/81. Wow this made the saw a little screamer. That said it went backwards in the big wood but picked up in the little wood.

 

[Miller Mod Saws]

So at this point I kept going but I started hacking on the piston. And when I say I went backwards it was in the big wood. I used the piston to lower the intake to 85. Thinking more fuel may bring it back. Nope then I trimmed the top of the piston to shorten up the blowdown. Nope even worse. At this point though the saw was a screamer and limbed like no other. But I killed it in the big wood.

 

[Nitehawk55]

I would want the saw holding the RPM in the wood , limbing is what it is .

 

[Miller Mod Saws]

Last but not least. I advanced the timing. I took .020 off the key which is roughly 5 deg. I did not like this at all. It cut ok under a good load but would pop under a light load.

 

[Miller Mod Saws]

So all this said I hope I didn't miss anything. And a new piston is on order for the now 107 saw. So I can put it back and then it will be for sale. Lol.
