Check out this tach. Should be part of our tool kit. Looks like .5 refresh or almost instant in some frames.

I have a race saw built on the Clone660 by a great builder and there were a handful of parts that didnt hold up to even rudimentary race testing.
He had me send an OEM piston, cylinder, circlips, piston pin, bearings (all), flywheel, ignition coil, crankshaft (this was before the good cranks were available from NWP in Taiwan, the FT cranks suuuuck), rope rotor and pawls, we also swapped to Caber rings for a little more compression.
I need to get that puppy out and make some videos with some of my other ported 1122s.

If anyone needs an earlier good 660 crankcase I think i have more than a dozen left in stock.

So basically the handles, covers and case were aftermarket, everything else was oem?

My initial interest in these kits has diminish substantially. Still fun projects to burn some time on without a doubt. But when it comes down to it, the end product still sounds pretty much like junk, unless you have a bunch of oem parts already on hand, otherwise they end up nickel and diming you to death.

Yet for some unknown reason i still many give one a shot.[emoji6]

Where to buy? It is for vacuum and pressure?

It is for vacuum and pressure and its an ebay special.... You can see loads of different makes but it's the same dance

That's a lot of people having fun with the kits. You may not have noticed it right in your face but Dave sells the very stuff in the kits you call junk and we buy and play with it. Did you see the new 440 kit. Big but not huge

Are you far enough along to Have done your testing?

The fun part is the exact reason I will likely end up with one some day. Not doubt a bunch of fun putting a saw together from a box of parts.

I don't know or care who sells these kits, that had nothing to do with my post. The fact is these aftermarket parts kits are what they are, and this thread pretty much sums it all up, that's all I was saying.

 

[Bedford T]

We like fun!

So basically the handles, covers and case were aftermarket, everything else was oem?

Aftermarket used - crankcase, all the brake components, muffler (duel port cover), tank handle, top handle, top cover, air filter cover, all the carb box fittings, intake tract, fuel and impulse lines, decomp plug, clutch cover, recoil*, tensioner, bar studs, oil pump and gear, av buffers and covers, sprocket, rim, all fasteners, grommets, wiring

OEM parts swapped out and why
cylinder - most builders want oem cylinders because they already have numbers they build to and a different cylinder means making a new roadmap, any cylinder can be made to run well
piston - lighter and again a known quantity
piston pin - much lighter and tapered slightly - nobody builds a better piston pin than the thin wall Stihl pin, they are commonly swapped into all brand saws for performance builds
bearings - when a saw spins 16,000+ only the best bearings will do
clutch - again at high speed, far beyond stock you want top quality
pawl spring and pawls - at 250+ compression the little spring bends out from the center and allows the pawls to come loose
ignition - builder wanted the earlier aluminum flywheel and ignition coil for the better timing options offered, these are different from the AM components which mimic the MS660
carburetor - we used a new OEM Walbro WJ-69 with a .074 main jet, the aftermarket carbs do not have removable jets
Caber rings - best in the business for most applications, better than OEM in many cases
air filter - I sent him the felt covered metal Farmertec filter (HD style), he didnt like how it sealed so I sent an OEM HD2 which i dont think is as good as the Farmertec HD2 replacement

the aftermarket carbs do not have removable jets

the carb that comes with the 660 kit has a replaceable jet, or most of them do. not everyone has posted so it hard to know.

 

[davhul]

I think some had a removable jet and some didn't. All mine did and I drilled them. The .62mm jet was almost 2 turns out on the adjustment.
Edit .62

 

[davhul]

Good to know, as you can see no jet. I might have to pull it apart some more and figure out how it works. Or did I get a paperweight....

Slurpj didn't have a replaceable jet in his.

 

[Bedford T]

[davhul]

so that might tell us when they made the other recent changes, new suppliers were used. i bet the earlier ones were as i said.

 

[MustangMike]

Question ... How are the Oilers holding up on these saws, any problems?

Thanks. Got to order for another saw, and just want some feedback.

Are the .062 and .074 in inches or mm?

 

[davhul]

Yes mm
