Grumpy thank�s for your explanation on setting the valve timing. Upon disassembly it was relatively easy to line everything back up as it should be. When find an engine that needs a full re- build and we agree it to be a worthwhile process this post will be good to refer back to as a guide. Your centre punch idea makes the most sense, so I will chalk that up in the memory bank when and if a Honda is on the operating table (my shed bench)
On a separate note I checked the ring gaps of the last 2 dismantled side valve briggs engines and they were both massive. They were not however lined up as Joe thought they might have been.
I have watched a few video�s on correctly installing the piston and rod during a full rebuild and it doesn�t look too complicated however I would appreciate some pointers around the importance of installing the piston and rod correctly before I attempt the process in future.
Thanks
Peter
