I won't be looking at changing any timing. Just more cleaning up edges and getting them chamfered. You can see the condition of the cylinder and the ports I am referring to, in my pictures I posted at the beginning. Definitely not gonna be making it a ported cylinder at this time. Sent from my...

The cylinder itself is just fine and doesn't actually need replaced, per say. There isn't any scoring in the cylinder. I wanted to play alittle and put a pop-up piston with caber rings in. Originally figured I would get a better AM cylinder since I am wanting to put caber rings in. But with the...

With several suggestions to just work over the cylinder that I have, what does everyone use for grinding on cylinders?? All I have is a dremel with the flex sheft and a right angle attachment. They seem a little bulky for grinding on cylinders, just my opinion. I could be wrong on that, since I...

Yes, you do make a very valid point and I should have kept my thoughts to myself. Just got under my skin enough, that my stubbornness kicked in. That is one of my downfalls and I apologize for it. Do I prefer to support and purchase US/local items, hell yes. But for learning and trying things...

I get that. I to have had bad experiences with Chinese parts. Rebuilt my 029 super with a farmertec ms390 p&c. Everything felt good during assembly. Once it got running, it had equal or less power than my saw had before. That was also before I knew a lot about checking squish, of which I...

Agree 100% with this. Even if I had an oem machine with a popped top end, I would be looking at AM parts. Not completely because they are cheaper than oem, but because I wouldn't be as afraid of wasting money on trying things and learning. I wouldn't be looking at a $40 kit, but definitely not...

Because I am not going to buy or can I afford to buy a brand new genuine roughly $1300 stihl saw, without bars and chains. And used 660s around here either goes for pretty penny or are completely clapped out and way over priced for such. I enjoy working on small engines. All of my saws are...

That is a good share of why I am wanting to use a different cylinder. Use this cylinder for playing with grinding. Rather destroy this cylinder for learning than a higher dollar cylinder. Sent from my SM-G996U using Tapatalk

Here are pictures of the cylinder. It does have about 2 hrs run time with the ft slug and rings, but that is it. You can see the defects in the transfer ports, that I was talking about. It would be the defect in molding at the outside edges. The top edge of the intake port is very evidently...

Been awhile since I have been on. I am redoing the topend of my FT 660 kit saw, currently all FT parts, except for the carb. I have a Hyway pop-up piston, caber rings for the top end and was going to reuse the ft jug. When I slide the hyway piston into the cylinder without rings, it feels like a...

I guess I will ask here before I start the return process, anyone need a tank/rear handle and plastics for an ms440? I ordered all those parts for my ms460 rebuild as a bundle and the Ebay seller sent me ms440 parts. I ended up getting the correct parts from another ebay seller. Just want to get...

I uploaded the video to youtube, then copied the share link to my post. The way I worked over my controls was I slowly shaved the arm that hits the choke lever on the carb, til it didn't over push it. It still can, if I press hard enough or fast enough. I also greased all the contact surfaces...

Sounds good. Just figured I would double check, since it will definitely be richer now. Sent from my SM-G973U using Tapatalk

Ok, so I just put the walbro 74 jet in my carb. What is the rough settings everyone is using to set their saws for tuning??? Sent from my SM-G973U using Tapatalk

Well, it is running and sounds good to me. Everything definitely needs broke in again since the only bearings not replaced were the main crank bearings. But I lubed the heck out of all internal bearings with regular stihl mix oil, except for the wrist pin bearing. That got greased with some...

Well, got my new parts and they are the correct ones this time. Be able to work on it tomorrow and hopefully have it done. The tank and plastics have been my total hold up on it. The parts this round are all FT parts. The main control lever on this tank assembly feels so much better than that on...

Spent extra money to get the parts from within the US, like I said. From the looks of tracking, should have them tomorrow. Hopefully they are the correct parts. The listing was for the correct parts. For that matter, both listings were for the correct parts. Live and learn. Gonna try to get some...

So, finally got my tank and plastics today. Opened them up and the plastics are for a 440. Very evident that they are. Already have a new set up of parts coming. Bought within the US, this time. Sent from my SM-G973U using Tapatalk

Kind of what I was thinking for repairs. I have been running stihl orange bottle at 40:1 and 92 octane e-free, through it and all my saws. I won't run any lower octane because of this saw in particular. I was running lower to save cost on fuel, but found one day after some hard use, the fuel was...

Yes, I definitely have a 38mm p&c. I just pulled it apart so that I could see what everything looked like inside. The cylinder actually looks really good, given what the piston looks like. From the looks of the coat of oil on everything, definitely have a good mix and richness for carb settings...
