WHAT? You are proposing replacement of the valve seats? Do you know anyone who can that job? It is common practice to replace vales and just re-cut or grind the seats.Putting new valves against old seats is poor practice. When an engine is down this far for a rebuild the head should be also be rebuilt.
Sorry I wasn't more clear. I meant, of course, regrinding the seats. A well done regrind doesn't need lapping, which can fling grinding paste about. A good shop will check the fit of the valve to the seat with vacuum or compressed air.WHAT? You are proposing replacement of the valve seats? Do you know anyone who can that job?

Thanks Spiderserie4! That's exactly what I was looking for. I hadn't found it in my overhaul manual, nor my workshop manual. I'm not saying it's not in there; I've probably looked past it several times.
What your looking at is how to set the throttle valve to its correct setting. This is set at the factory and should never be messed with.I am going to show my ignorance here, but I love to learn new things, about anything. The Alfa manual shows a meter being used, which reminds me of my old vacuum meter that I used to set the air flows on SU carbs. Is the AFI meter a more accurate vacuum meter? Second, 1 1/2 percent of what, idle compared to max air flow? What is the stock factory percent?
Uhhh. The chain accelerates toward the exhaust side when the throttle is pushed. Therefore the open end of the link should go to the INTAKE side.Always put a towel under the chain when taking the master link out. I realize you probably already know that but just in case
I use a small stub flat head screwdriver to take the masterlink apart. From the intake side of the car put your left hand under the chain and with the right hand put the flat head on the open end of the master link and pull it towards you. The open end always goes towards the exhaust side. The bolt on the front of the head that locks the tensioner in doesn't have to be gorilla tight, just tight. There are a lot of these little things that will help you enjoy the process and have a motor you can be proud of. :thumbup:
