Hi there, just wrapping up some loose ends on this build. There were some ideas kicked around in this thread about what would be needed to be done to make it work
http://opeforum.com/threads/calling-stihl-hybrid-builders.9593/
I had a bunch of spare 036 parts that needed some new life and the local CT GTG coming up so decided to give it a shot.
First the cylinder mounting holes need to be slotted just like a 044/046 hybrid. To address the 2mm shorter stroke, about
.100” needed to be removed. Mattyo took .050” off both the case and the cylinder( thanks Matt!) I also got a spare hyway 044/ms440 cylinder from him. I’m using a 044 hyway piston(10mm pin to fit the 036 crank)
The larger piston (and longer skirt)was too large to fit down into the case so a little clearancing around the skirt area is needed.
The piston comes close but does not touch the crank.
After cleaning up and widening the intake and exhaust I ended up with
100, 120, 80 for port timing
Next needed some material taken off the outside of the transfer port to clear the flywheel and a few fins trimmed to fit the original plastics
Still need to drill and tap a hole for a threaded stud to secure the top cover.
Decompression port lines up perfect.
Still working on handle, using 044 carb swapped on. Will update tomorrow.
