Yes sir all 044 stuff if I was to do it again I would try to find a shorter piston from a just or something if it exists with as big of a gasket and as much as I took off the top of the piston .100less would be a much better starting point

You may have to rebroach the flywheel keyway. Would be interesting to see what degree the flywheel magnets align with the first coil leg in degrees on the standard 036 vs the 036/044 crank you made. I bet it’s off and accounts for your poor running issues.

I measured roughly and I mean very roughly and it is indead off by at least 4-5* I got tired of trying to measure and freezing so it's good enough to note that if anyone does one of these just advance it some to start. Next time I get around to it I'm going to just shave a little more off. Now I don't know if it is off due to the crank for the different cases or flywheel size or a little of all 3

Lovely little update no vids yet, hopefully that will come tomorrow or so. I have filed a total of .032 off the key and it seems to start better yet not much difference in response. However that is due to the choked out muffler and air filter. It has this type of hd filter and it still has the green peice in side it, the green will be coming out tomorrow may even get a hd2 style eventually.

On top of that it has the baffle in the muffler still, I don't really want a open muffler so I'm leaving it, but it still has the secondary baffle in the cover piece, I drilled holes in it but I'm just going to cut it out completely. Also going to open the small hole to the left on the muffler up about triple in length. That should get it much better flowing IMG20240202104901.jpg
Also went ahead and 3d printed a choke lever had to cut it up and such to fit but works excellent.IMG20240202104614.jpg

I measured timing and it is around 26-27* now I may take a little more off the key but doubt it will make much difference. The big thing is I unfortunately have to run a 8 pin sprocket. When I bought this bar I bought a pack of 3 chains from the dukes website idk how good the chains are compared to Stihl but they cut. I'm going to do some timed cuts with full comp, semi skip, and full skip and see what I get. This has some pretty decent torque as is but that 8 pin isn't really doing me favors. If I end up taking the cylinder off I may raise the exhaust another 2*.

Final pic of the saw will get a full weight once the dogs show up and I fuel it completely compared to my 261 filled. Would also like to put a elasto start rope on because it's a bit rough sometimes as is if the decomp pops to easy.IMG_20240202_103755_01.jpg

Final weights completely filled the 261 vs this. Both 20" light bars one 325 and one 3/8. I unfortunately can't run it or get a video the home made gasket blew out and it won't run right. So I'm got to find someone that can make me a gasket out of 1/16" copper preferably. Or attempt it myself.IMG20240203123453.jpgIMG20240203123504.jpg

Made a discovery while a 044 and 36 chare the same bearings the crank seals are different on the flywheel side. I used 036 seals. 044 has a 1mm small case than a 034/36. When I replaced it the first time I used a 036 seal and it has blew out on me and the seal is buckled like it's to small. Well it is, the 44 uses a 13mm seal vs a 12. So I did some digging and found a seal made for efco (yes not echo) that is a 13x20x4.2 Wich will fit both the crank and the crank case. Pn 94500004. So I'm waiting on that now.IMG_20240206_154108_01.jpg
