checking timing
But be sure you have any carb/fuel related issues solved first.

A phone call to S&S may be in order, if you're interested in finding out what stroke you have. They may be able to identify your wheels from the numbers that you have. It's worth a try anyway.
No easy answer to this one. Research and form an opinion. Ultimately, it's personal preference.
IN 1971 I Built a Stroker motor (still have it) from a 1970, 4& 5/8 stroke (77 inches), S&S wheels, at that time ALL Sportster S&S wheels had a 40% timing mark (S&S said that was for fuel engines). You timed it at the edge of the window to get 45% for gas ( gas was good then!). If I remember correctly, the timing mark on stock flywheels for all 883s was 45%, will have to look in my service manual to be sure or PINION will correct me I hope. Mine has 11 to 1 compression, never made a sound (detonation) at 45% with the gas back then.
im going to get the # off crank and find out what i have had it running saturday now she wont i get some smoke out of pipes and a pop out the carb but she just dont want to take off still playing with the carb
Static Timing 101
All this is assumimg your points are good and correctly gapped.
Switch off. Get it at TDC. Loosen the points plate and turn it clockwise until the points JUST START to break. (It's best to use a continuity light or DVOM with an audible signal, a simple ohmmeter will work) Lock it down. Then, if it doesn't fire, look elsewhere for the problem.
