Did some crude port work (actually improved upon my previous work) by widening and flattening the intake and exhaust and enlarging my bridge ports. I also slightly elongated my upper transfers after noting that the factory jug has wider ones.

My work is crude and not as pretty as some of the masters that post to this site, but so far I have improved performance each time I've dabbled, so finger crossed it continues!

This is a New West 440 Big Bore cylinder. I love that they have tight D combustion chambers, and their transfers also look better than most aftermarket. That said the intake and exhaust ports generally need lots of work.

Hopefully, when I pair this jug up with an OEM piston, it will impress!

Sorry the pics are just the best I can do with a cell phone. Also tough to get the light right and not block the light when you take the pics.

My newly ported cylinder (Big Bore #5) came to life today.

I was not real impressed with how Big Bore #4 ran, the port timing #s were not that great (Ex at 95), so today I ripped it down and put my "re ported" Big Bore jug #5 and an OEM piston on frame #4. Squish with the OEM piston went from 0.20 (with the NW piston) to 0.17 with the OEM piston.

I could not believe how clean BB #4 P+C were! The pics of the cylinder did not come out, but look at that piston, and I did not clean it at all!!! Looks like I took it right out of the box!

These NW BB pistons seem to be of good quality, and weight the same as a Meteor, so I think I'll save them for some 460 projects and use the lighter OEM on my Hybrid and BB kits.

I let the sealer dry for 2 hours then started her up. She kicked on the 8th pull (just enough pulls to make me nervous), then started right up and ran very clean. Minor adjustments to the low and she idled real nice (with the Lo screw about 3/4 turn out).

She ran good. I'm neither disappointed nor ecstatic. I'm not sure if she has the RPMs I was hoping for, but she has good torque, and when you lean on her (noodling Oak) she just slows a bit but does not stop. I like that in a saw! Heck, it does not even have a third of a tank through it yet, so it may break in a bit, and maybe RPMs will increase if I lean her out a bit, but for now I want it to be a bit rich. The saw was well mannered, idled well, re started easily several times, and did what it was supposed to. Also, it has out of the box RS on it, and I'm used to running square file.

I’ve had multiple failures with aftermarket 1122 av mounts. The main culprit has been the tank mount. The rubber part sheared away from the metal on two saws (one was mine).

I’ve also had a couple AM buffers fail. I got three years of use out of one set, and six years out of another...only noticed during tear downs to remove AM impulse lines.

Speaking of those, we had a failure with one. It’s an 1127 line (used in 1122 as well) in a ms290. Only got a couple of years of low use. I had three in running saws so I removed them.
I therefore do not recommend AM impulse lines and would be cautious with some AV mounts.

Edit- updated to reflect years of use. One set was built up in 2014.

I sold one of mine to a pro firewood place … they use it every day … hard … and it has been holding up for several months now.

I did insist they run Saber at 40:1 … seems to work well for me and for them.

I kept the one that dyno-ed at 8.6 Hp, but this one was darn close to the same. They love it!

Could you post the parts changed out from the kit?
Or what variation you have used. I've been researching this idea. Just want to have more information.

Most important, OEM piston pin bearing, OEM Elastostart pull cord/handle, Cross Cylinder (ported), Meteor piston.

Sometimes I replace plugs and fuel filters, but not always.

Yea, I forgot. I don't replace them, but I pop the cap and glue them down with PL Premium (You should sand and dampen the metal a bit to make it work right).

Otherwise, those tops pop off, and you are vulnerable to eating the decomp.

I would just go with the OEM decomp.

Watched quite a few videos that are helpful from the fleetcommand channel on Youtube.
I hesitate to buy a kit from the farmertech site because of all the shipping delays from the east.
How many bought kits from HL Supply?

I’d like to get an ms660 clone to build a play race saw with. Been apprehensive to do so with all the talk of quality being questioned.

Hoping prices will drop. At HLS the are $299. plus shipping. Ebay prices are the same also.
Lots of guys that bought them at first paid less than $200. I guess they are getting popular now.
If anyone sees a cheaper deal post the link. I'm a confessed tight-wad.

Yea that’s why I don’t see it worth it to buy them being that they aren’t that cheap plus you still won’t feel warm and fuzzy about them
