I'm working on slowly building my 660 kit and following steves "New England Saws" yt build videos.
I'm to the point of doing the leak test and I have the carb adapter, put the piston at TDC per the book and tested and it's dropping from 15 to 8 in 14 seconds. So pretty fast.
I have a stihl decomp valve in and I put better hardware on the intake hose clamp (which ended up breaking the clamp so I'm going to have to replace that)
Is the test only testing the top end? The only thing I haven't done is put a drop of oil on the shaft seals to see if it sucks it in or not but I'm fairly convinced my issue is the decomp valve or intake boot mating with the adapter.
The only other thought I had was block off the adapter and test in the decomp valve port?
