Can anyone tell me the typical timing, ignition Before Top Dead Center, for a magneto equipped Q 50 ? And, can it be changed ?

Should be 28 like all the rest...You could take the key out but the crank is pretty small and has a big taper, be sure you use some Loctite and get it TIGHT...Watch out, I had one here last week with a left hand thread...I stripped it trying to get it off...Left hand 5/16 nuts are hard to find in Flagstaff, but Copperstate has 3 left in stock..
Use the thinnest base gasket you can find or make, the Q50s run best with the least piston to cylinder clearance at the top...

I am intrigued... How do you measure the tining. Is it at he start of the magnets passing under the center of the coil, middle (between the two magnets), or end? I'm curious becuse I have a Quadra 35 points ign engine. I also have a spare coil from a CDI engine, and I was wondering if I coul just put the coil on, remove the flywheel key and adjust the timing, thereby eliminating the points.

Thanks Ralph. A friend down here has been telling me that he sets his Quadra's at 35 degrees BTDC, and I just wondered how he might be doing that ?

Might just be more BS. Probably would make for a real shaker.

You pull the key out of the assembly, get a degree wheel, and rotate the magneto 7 degrees counter-clockwise while looking at the front.

That will advance it from 28* up to 35*. Better have a Dynotron starter or a really thick leather glove the first time you grab hold of that sucker. I got a 54cc chainsaw conversion up to about 35* once with a C&H ignition. I was moving my timing ring around and trying to "static" time it by starting and taching, then advancing a bit more. It smacked the heck out of my hand, first time I flipped it. I was doubled over and dancing around in the driveway with my hand between my knees and screaming for my mommy. [:@]

Next day, I went back after it with my degree wheel and realized my stupidity. 35* was just a teeeeensy bit too much for that engine. Better be carefull with that Quadra.
