Just curious how you guys find TDC on a chainsaw within one degree accuracy. Had a phonecall today at work from an AS member and had a short discussion about my method. I will pass on a little trick after 10 posts.
 
Put you're thumb over the spark plug hole, when it stops blowing, it's close enough.:chainsaw:

I put a degree wheel on the crank. I install a stop in the spark plug hole. I check the stop setting in both directions on the degree wheel. Split it down the middle and you have TDC. Mike

Watch piston through exhaust port till it stops moving upward.. Then place dial ind. on flywheel and rocket till the piston moves and take half of reading.. now give it to us


(just burning posts here)
Shoudln't that be rock it one way until the piston starts to move, the rock it the other way and split that in half? Thats how I degree cams at least.

Excellent Mike. You don't need a degree wheel though. If you install a piston stop and thread it in far enough to stop the piston about 15 or so degrees BTDC, (doesn't matter if it's 10 or 20), mark the case and flywheel with a sharp carbide scribe, then rotate it the other direction and mark it again, TDC is exactly half way between these marks. For some of you this is very obvious, but for others fighting with dial indicators and such this is a very simple and accurate method. I posted this because it was a topic of conversation at work today with someone on the phone. Cheers.
 
Sheesh, all that for that? And it didnt change that fact that youre still a doosh bag. Im posting this because somebody on the phone at work told me you were.:cheers:

I would give you a nasty response, but anyone playing with McCullochs deserves some kindness. It would be like giving a wedgie to a Down's Syndrome kid. Cheers you poor little bugger.:cheers:
 
When you build a husky or stihl that can beat my Mac I will come on AS and give you a full apology until then go blow your bagpipe Slimonhoser

If you are good, we can go for ice cream later. *wipes drool from MacDaddy's bewildered face with hankie*
 
LOLOL MAC, where in the world did you get a picture of a Saltspring breathylizer? They are a rarely photographed phenomina and often used to practice milking.
