Timing question

[Swiftdoog]

Just to correct myself, when I said 4º with no vacuum, I mean the second vacuum pot (remember my dizzy is dual advance and this pot pulls 6º more with vacuum, oh btw I found the dual advance canister I needed forgo to tell you), and with that second pot connected it pulls 10º, it doesn´t affect cranking time since it only activates when the engine is already running, by the way, the crank is like lighting smooth now .

Also, this vacuum advance has a screw that makes it adjustable, now I can see at 1500rpm a slower timing progression, like sitting at 12º, before it will jump to 20º (under normal circunstance could be right but in my case is too much, so I needed a slower progression timing curve).

And I would like to quote:
"...IF a head warps over say , 0015" then its oven heated to relax said warp
all head shops USA (aluminum) do that and then measure warp again. (may go to oven again... yes skills max here)
then shave it LAST, if at ALL max 1 to 2 thou max. in fact its what is called a clean up cut, to get max gasket seal. only..."

Dude... that´s way too advance for a third world country like this one, what you say is the correct way, but here they only shave and shave and shave

Gonna quote a picture of yours:


You see that peak that the water pump has? I remembered milling it because the head (with the gasket on) would touch it, so you can guess how badly shaved it is and you can see that peak is slightly above the head gasket line.

And yes, the "suppossedly" correct belt is 103 tooth, apparently is the correct one, but also remember that I was over tensioning the belt because I was actually not following the instructions right.

So far I am still testing, retarted the timing 2º more just in case and so far I am at 2º no vac and 10º with vac at 700-800rpm, and at 2000rpm at least than 18º. Yep, that´s too little advance but is driveable. Some day I will get a new head... some day...
