In relation to the maico decompressor ,the stroke or maximum opening position is adjustable.
You must remove the decompressor from the cylinder and the cable from the device to do so .
So if you adjust it you can regulate release.
As a secondary issue , Husky imports were at one stage fitting a vaccuum operated decompressor to the watercooled 360's that had very high compression and were very difficult to kickstart.
Decompressor was located in the head.
We have ordered a couple of the decompressor modules and we are going to give a try.
We will keep you posted
