Thought I would post up my experience for others. I had another post on problems I had with dropping a lock washer in an intake.

Problem that can bite you, is these horizontal engines have intake ports that face up and increase the chance, like a funnel, least for me, they will catch something like a washer bouncing. I usually try to stuff a paper towel in them unless I am in a hurry and think I am so good no bad can happen. What can you say, paper towels are cheap insurance?

Here is a link to the original thread and picks of the removal.

That washer sitting there pretty can be.

Once you do a Head Porting, you will never look at a detached cylinder head the same way and I could not resist scrapping the considerable carbon of the surfaces and going after it with a polishing wheel.

I did oil the threads with Rotella on reassembly hoping to get an even torque, after I pondered it all reading this article.

I torqued it to the lowest Tao Tao cylinder head spec. From this spec sheet.

Upon start up, it had a knocking sound, like the crankshaft weights were hitting the cylinder sleeve. Fearing I had over torqued it, I backed off the torque and retorqued to a lower spec of 12 NM because I had used oil on the threads. I reset the valve lash. After some time the knock/rattle seems to have gone away pretty much. I rechecked the valve lash again. There has been no effect on the way it starts or runs.

Crosshatch looks good

Good practice, make diagrams for re assembly
