what are you using for a formula?

what are you using for a formula?

AutoCad
Doing a physical layout.
Give me any diameter and I can tell you the distance for any number of degrees.

If you don’t have a degree wheel. Put a line from your jug to your flywheel. Then put another line 5 mm to the left. And advance it that much. 5mm of movement is roughly 6 deg.

I checked with your way a bit and calculated roughly 4.5 -5 mm movement with 1/3 or .025 off key. Close enough for me. It’s hard to grind that cast key/measuring it and I don’t wanna risk taking too much off by accident.

If stock timing was around 28 degrees like mentioned previously in the thread and I got 3-4 more degrees advance I should be in the 31-32 degree range on the money in theory... my head hurts now lol.

Go a little at a time. You can always take off a little more

It would be awesome to see what gains can be had on a stock 79XX from advancing timing only. I've heard mixed opinions on advancing the timing on these, but usually those are coming form various guys that are porting them.

Don’t forget, the OEM coil has a timing advance built in.
272 coil don’t have it.

Oh, and I don’t even use keys any more.

They’re over rated.

What did you use to polish that muffler?

Yes they are in need of a D handle too.. I started mine (recently acquired this week) this morning and found it harder to pull over than my 281xp. I was surprised. It does however have a teeny handle on it.. or is this the standard size??

 

[Wilhelm]

Hard to tell, but I think that doesn't look like a OEM handle.

Mine look like this.
