Preface: This is the first large McCulloch I have worked on. 1-71 3360 block.
When pulled over slowly, I hear an air release sound at compression, almost like a decomp. I can’t see a manual decomp. I have consistent, weaker spark and cannot get it to start with mix prime down the carb. It is much easier to pull over than it should be.
Question: Does this saw have a decompression valve or similar release? Where are likely leaks before I dig into it?
This is a removable head saw (which I have not worked with before) and the piston and rings look great through the exhaust port.
Thank you!
