Hi all
does anybody know where number 1 is on V8 AQ211a distributor cap, I think I might have a crossed lead but need to know where number 1 on the cap is to start.

Many thanks
 
Same as any other SBC.
Keep in mind that how the distributor installation idexed the shaft, the rotor may not be pointing to # 1 when # 1 is at TDC C/S.
Is it NOT mandatory.... but does make sense to do it this way.

Hi from a Newbie.

Sorry my first posting is a question and I haven't introduced myself previously.

I have been searching for help with a problem I have with the same engine and came across this information.

I recently partially re-built an AQ211A engine fitted to in my Fairline Sprint. I managed to get the boat really cheap because of the damaged engine.

I had one head skimmed and changed a jammed valve on the "even" cylinder side.

I re-fitted the distributor and all seems to run well with no load, and the timing seems to be OK (as long as I'm using the correct timing marks on the engine....Not sure about that).

What intrigued me about this diagram is that I find my No:1 *seems* to be where you have drawn the No:8.

Maybe I've messed up big-time??

I cannot get any more than about 10 - 11 knotts out of my boat at the moment, and under load it will never rev to higher than 3000RPM.

Also, (and I don't know if it's relevant), the exhaust riser on the "even" side always seems to be much much hotter than the "odd" side after the engine has been run for a while.

Do you think I've got my distributor all wrong?

As for the timing marks. The marks on the pulley are fairly clear. But, there is a "saw-tooth" plate on the block that I assumed was the corresponding marks, and I assumed the larger cut-out "tooth" is the one I should be aligning my marks with.

Thanks for any help or advice anyway can offer.

Shaun.
 
Shaun, best to begin a new thread specific to your issue.

Please note how important Ignition Timing is to a Marine Engine.
We DO NOT guess at this, nor do we set BASE advance, and walk away.
There are other aspects of this that require utmost attention.
On one side..... we leave power on the table! :(
On the other side.... we risk severe engine damage! :eek:

I'll look for your thread!
