How do you go about " locking out " the advance in the distributor?

I don't think you can with the stock Merc. distributor. I replaced mine with MSD. Any distributor you have to glue the rotor in place is junk as far as I'm concerned. It's easy to lock out the MSD by removing the springs, weights, advance bushing. Then you remove the gear lift the shaft up turn 180 deg. set it down lining up the pin and hole, but the nut and washer on the pin then install the gear and it's locked. I don't think I missed a step.

"Locked" , sounds like the cover to a problem. AGAIN!!!! has anyone run the 6 cyl control unit?

Ghittner,
Locked timing is not the cover to a problem.
Also, if you want an answer to your question, I suggest that you start a thread instead of hijacking this one.

That is correct for the msd. The merc distributor is "locked" since it has no advance mechanism and relies on the electronics in the box to advance the timing. I have used a merc dist with a crane hi-6 for a set advance.

I've run the V6 box on a 177/454 and 250/502 combo with great results. Excellent choice IMHO. Add an MSD if you have carbon fowling at idle.

So when a locked out disrtibutor is in ,the timing is always the same . ?IMy timing seams not to fluctuate with a timing light at 1000 rpms or 3500 ?It stays the same . These are Joey Griffin blower motors ? He knows what he is doing im sure. Am I missing something . Or is it the same all the time with a locked out distributor ?

YEP. It will be the same all day long IDLE to WOT.

Thank you thats what I needed to know !!! But it seams odd to me to be starting an engine at 30 degrees . Is this ok. ? Sometimes its hard to crank .
