Stihl 066 v's MS660 v's MS661

[mdavlee]

Fix the 066 and get a 661 to play with. Hopefully you can figure out how to hack the fuel system. The system is a small box and the carbs cost the same as the old carbs.

Does anyone have any experience with the aftermarket replacement cases?

I've used a few.

The jury is still out.......but I've gotten no negative reports.

 

[jmssaws]

I've wondered about aftermarket cases cause there cheap enough.

 

[Mastermind]

The ones that I have used were made in Italy. Everything bolted on perfectly.

Whats the deal on the 661 adjustable carb swap, guys?

Not something I would do on a working saw........but still interested in the details.

 

[jmssaws]

I believe a 660 carb is a direct bolt on, wj69 or the likes. No mods needed. I think

 

[jmssaws]

I'll get with you in the next few days on these cases clint.

What's the best aftermarket p&c you have used for a 660 randy? As far as fit and finish,timing and so forth.

The Mako standard bore jug is the only one I've ever seen that was worth a damn. The piston in the kit is iffy at best though.

Thanks. I've spent a bunch of time trying to make a big bore run,395 piston and all but it's still pretty common. I'm gonna try the standard bore.

066 Big Bore with a 395XP piston......064 bottom end......on one of Gink's pipes.

You'll not find what youre looking for untill you run an 066 that is ported for and runs a pipe

 

[jmssaws]

I'm not going the pipe route,looks fun but I'm interested in Stock appearing race saws. I've got a couple to build in the spring so I'm trying to study all I can.

My big bore is stout but any of my oem cylinder saws are faster. It's hard to overcome the poor quality.

 

[Moparmyway]

I'll be home this weekend and hopefully get to run an experiment on a few welded mufflers ................... gotta have dual outlets though for it to work well, if it works at all.

 

[Mastermind]

That same saw.......before I ported it for a pipe was not as fast as my 066 with OEM jug either. I'm redoing that saw now......and using a OEM top end. The 395 piston is too heavy.

 

[jmssaws]

It is to heavy for the long stroke but man does it have skirts.

You don't need to push the play button to see tha piped MM066 is quickly pushin the chips, they look like a blurr being shot out the wood so quick.

What are the meteor cylinders like?
Everyone seems to like the pistons but I never hear much about the cylinders.

Not as good as their pistons by a long shot.

Hyway does a better jug.
