I Hope everyone's doing well.

Just wanted to say I appreciate you all. I know dealing with my insanity takes from your sanity I hope everyone has a good day! Todays project ms260 pro muffler mods(I'm doing multiple for someone) and hand cutting a crank case gasket. Yippy!!

Sadly The 260 is back with its owner and I'm terrible at taking pictures not that I can't I just forget to. How do you download a video?? I did send him a video( althought I recorded it as a teaser video) you don't see anything but you hear it's first start up.

I'm Actually kinda proud on this build because it went through a through tear down then a good cleaning including completely cleaning fuel tank. I then I ported it, raised the upper transfers with.... a Dremel cutt off wheel! Yes I know not a good way to do that. I do not have a right angle hand piece. I Spent about 5 hours cutting the base. Another improper technique, big piece of glass with various grits of sandpaper. I squared off the intake and slightly widened the exhaust then I reassembled it with all new rubber components(filters,fuel line, impulse line, oiler hoses,new carburetor parts) base gasket delete loctite 518 was the sealant i used for this one, deleted the decompression valve. All without a timing wheel.

Yes I know I took some bigger risks on this one. The videos I'm wanting to upload is it's first ignition. I didn't have the first 2 pulls recorded but that's when it burped 2 pulls from completely empty lines and then the 1 pull in the video and it fired up and almost had perfect idle. I hadn't even began touching the carburetor besides the 1 full turn from seated. The second is very short because I had just gotten a new cell phone and for some reason anything longer than 5 seconds was apparently too long to send in a text message.(I went from a Motorola I bought at Dollar general to a google pixel 6a and 5 seconds is too long? )

The picture without the cutt off wheel in it was not the finished port work. That picture was just after the initial cut. I cleaned it up with a diamond ball burr and slightly widened the lower transfers with a carbide burr while still maintaining the funnel effect. I cut enough of the lower transfers that the number 4 imprinted in the metal is no longer visible. These 2 pictures were taken on that cheap dollar general phone. Quality is kinda crummy.

I do have a question for you experienced porters. do all the pro line Stihls have such thick nicasil throughout the transfers? This one definitely did.

Get yourself one of each of these:

Angled Rotary Porting Handpiece Kit

This small head, angled handpiece is great for grinding the upper transfer ports of small two-stroke cylinders. It works with any key drive, quick disconnect, flex shaft grinder such as Foredom, Dumore, Mastercarver, some Dremel, and many others. The push-button style dental head uses 3/32"...

Awe shoot, might as well get yourself one of these while you’re at it too: https://worksaws.com/products/digital-degree-wheel-kit

Absolutely no to the harbour freight flex shaft.#1 I already have a burnt one #2 I have a foredom tx with the neoprene sheeth (ever since I've swapped to their neoprene I've had no kinks develop in the inner shaft) and a h8 hand piece the h8 is in the picture. I also have the 44 hand piece both lengths the original is a square drive though and a 30 hand piece. I also have a vevor "foredom" Sr which still works flawlessly since I received it. Well flawlessly for what it is a clone. The Vevor I bought first because if it's a tool I've never used before (especially something made to do hobby type work) to see if it's something I am going to like before I dish out the full amount. I had the Vevor for 2 minutes after that I was on foredoms site. TX with square shaft a replacement inner and 2 regular key tip shafts h30 hand piece the short 44 and metal pedal placed on order I only used the wheel made by Dremel. My Tx I treat like it's my child. Every night I take it off the hanger piece I made and it's put into a big shock proof water proof case then brought into my room. Needless to say I absolutely adore my foredom I refuse to use foredoms grease though. Not because it's not good grease I mean it's specificly designed for the thing but it's smelly super lube is what I use on it.

I keep meaning to get a right angle hand piece but I keep buying freaking chainsaws and parts

I do have a question for you experienced porters. do all the pro line Stihls have such thick nicasil throughout the transfers? This one definitely did. View attachment 433100View attachment 433101

I'm not an experienced porter, so take what I say for what it's worth. I just dabble with it and try to learn from those that are professionals. There's plenty of them here.

Porting is all fun and games till you destroy a 200 dollar OEM cylinder. If it's someone else's cylinder it's that much worse!

I have nothing against sanding a base down. To do it right (as good as can be expected) it takes time, a flat piece and a caliper to take dimensions around the base in different location to make sure your taking the material off evenly.

Raising ports without a degree wheel is about like seeing your target, than closing your eyes and trying to aim and shoot. Then again, without a degree wheel you never even get to see your target. You're just blindly shooting in hopes of hitting. Get a degree wheel. You can get a setup for under 30 bucks.

Don't worry! I used to do it just like you! But, since being on here I've learned there's better ways.

The only way I know of to post videos is through YouTube....

Yeah I'm definitely aware of all that. I had/have a back up OEM cylinder for this particular saw just in case. Degree wheel is on its way just you know how the postal service has been. Maybe?!? I know in my area it has become absolute *s-word. They dropped a package off on the ground right next to my mailbox on a rainy day. The package had cat litter in it.... So idk what's going on with the degree wheel it was supposed to be here 4 days ago.

Sanding the base I went with the same method I've used on multiple cylinder heads. Mainly LS but there was 1 set from a Engine judging by your user name I asume you've got experience with. Good ole 7.3. (I swear I had blood vessels explode all over my body when I saw the new "7.3".... why?? Just why??? ) the weight of the cylinder is what applies downward pressure, a straight edge and feeler gauge for measurements. I know heads don't have nicasil to get through which is why it took so long. I've been able to "resurface" heads a hour a piece depending on material. But that's only of they were not overly warped. There was 1 set of heads i ended up paying a shop to resurface with a machine. The owner went in and just removed them... starting with the front bolts working backwards with a impact wrench.... More than likely his removal was what caused the warping to begin with. I've always removed them by reversing the tourqing sequence.

I'll upload those videos though. For blindly shooting I may have not hit a dead on bullseye but definitely still hit the target. I put the saw in some oak after doing the port work and it felt like it had way more torque than before. I got it 4 stroking a little over 14k. I take it more close to 14k then what the tachometer said. Cheap tach.

And the part you said don't worry I use to be just like you. I'm pretty sure most could say the same thing . People are constantly improving on technology and ways to get something done. I don't believe there is a single person that can say they are a true master at doing something because there is always room to improve and grow.

this is not the first saw I've done for someone either. This one was just the first case where it fired up relatively quick and almost had perfect idle. But out of all the saws I've done no body has come back complaining nor had a weaker saw then when I started. I guess lucks been on my side which is honestly a unfamiliar feeling for me. These have also been people I know. Currently I refuse to touch saws from people I don't know. But each one I've done I've gone into with the thought of if I mess it up I replace whatever it is. Be it cylinder or the entire saw.

With that being said I do want to get all the proper equipment to do this kind of work. This journey has been the most fun I've had in I can't remember how long and everybody here inspires me to keep going.

It's like addiction admitting there a problem is the only way to fix it... I tired that they refused to take me in. Something in the report about heaven doesn't want me and hell isn't ready for me.

Don't let that become a crutch. There are many here that have been where you are/were. The wisdom and experience here you will not find in many places. Lean on it and let them help. You are among friends here, and will be needed in the future to help others. You can get through this, if you truly want to.

Sanity is overrated.
My wife said I was insane when I got to 100 saws, then at 400 it was criminally insane. Now at 800 and growing well I am just plain nuts
