Thanks for the concise explanation regarding the engine being at TDC on the compression stroke
Last night I lapped and ground the valves. Both clearances are now within the desired range.
I also cleaned the valves and cylinder head of excess carbon. The valves sit in the seats nicely and do not wobble from side to side.
I don�t expect re-installing the valves will be difficult noting Joe�s trick with the cable ties however I just wanted to make sure I hadn�t missed anything before I go and re-install the valves, springs, retainers, chest cover and cylinder head.
Once you confirm I will go ahead and finish the job tonight! Lets hope it works.
