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.
