You folks that work on Wisconsin engines, what do you use for a valve spring compressor. The compressor that is shown in the VF4 book is too large to get around the valve spring seat. The seat is real close to the casting part that is threaded to hold the valve tappet inspection plate to the cylinder block assembly. There is also not enough room on the other side either. I am working on a VH4 but would think the valves are the same in both engines. Maybe not?
I used that same valve spring compressor when I re-built a VP4 years ago. But the VP4 and VG4 are larger engines.
