HOW TO- Sparks Advance Key Installation

[Gatekeeper]

I guess if a person was thinking ahead they could crank the flywheel til the "t" mark lines up at TDC, remove stock key, install the new advance key, turn flywheel gently to the left to index the flywheel with the new key (without turning over motor) and place the cover back on temporarily
Then mark the flywheel thru the sight plug for a new timing mark with a marker, remove cover and lightly file a new "advanced" t mark in the flywheel.
Wish I would have thought about this before installing mine.
Anybody do this or something similiar?

Installed my key yesterday evening after work. Thanks for the write-up Tri5! With this write up and the one in the 'articles' section, it made the install a snap. MUCH better than the instructions that come w/ the key.

i'm curious to hear how it runs with the 406 10:1 because thats my next setup when my rings go and stuff.

Well, I'm going riding tomorrow, I'll post up when I get back. I can't wait! I started it up today to let it warm up (and bake the high temp black paint I sprayed onto my head pipe while I waited for parts) and revved it a few times, and it seemed to want to rev quicker and almost lighter (more repsonse?).. though I did have the airbox off, it's been running rich and it was cool. From what I heard it's supposed to be fine for a 406 with up to but not including a 12:1 piston. I may take out the stg 2 cam and swap the stocker back in to see if it works any better with my 406 10:1. I'll proly reply again after that little experiment.

Thought about your post while I was out in the garage doing this, and I came to the conclusion that it would be safer for me to just check through the plug hole for TDC instead. I mean usually when I'm checking for TDC, I'm adjusting my vavles and have the front end off anyhow...
