oleomac starting

[half]

My 952 Oleomac has a start problem. If I push in the decompressor and give choke after a couple of pulls it fires.When cold easy. Then push the decompressor in again and it seem like there is no decompressor and it nearly breaks the cord
I have removed the decompressor and it is all ok the ports are clear and I can blow air through it easy But the problem returns when I replace it.
I am thinking it is preigniting for some reason

did you check the decomp button clicks in and out,sometimes they go loose and compression on all the time

You should not be able to blow through it that easily. I have had this same issue on Husky 575. Simple fix was to replace decomp with a more restricted  Stihl decomp valve
