The last couple decomps I used on machined and ported 088/880 were actually 1128 decomps. I drilled out the hole in the 1128 decomp to 1/16 and then drilled another 1/16 hole 180* from the first one. They worked great.They stay open better, especially on saws that have been machined to raise compression, plus you can drill them if they are borderline, which gets them to work again.
One of these days, I am going to take a few of these Stihl decomps and see about adding additional openings to them, see if it helps
