Sputter because of Bully Hawk soft start

Sorry that's got corrupted.try this link  

I find it difficult to follow Ignitech's explanation but according to them, with the original flywheel, their units retard the spark to just after TDC up to 500rpm, as well as delaying the advance to 26 Deg for several seconds as does Rotax. Here it is! In the UK these units have become very popular and are highly regarded.

Final try!

Standard original system start at 4° BTDC (pickup at end of lobe) and jump to 26° BTDC (pickup

at begin of lobe) at 600-800 RPM. Original system with additional "soft start" system start also at

4°, but it keep this starting advance 10 s regardless of engine speed. Original system with new rotor

start at 3° ATDC (pickup at end of lobe). See old and new rotor on photo below. See also this video:

Our system is different. It not only "jump" from 4° to 26°, but is increase advance smoothly

according advance curve preselected in setting software. Next function for better start is value

"Lower advance by start %" in software. This function will delay advance according value. When

value will be 0 - it will not delay advance. If value will be 100 - it will delay advance with angle of

pulse lobe. If value will be 50 - it will delay advance with angle half of pulse lobe. Standardly we

use value 20. Pulse lobe angle is 26°-4°=22°, so that delay will be 22x0.2=4.4°. This is little bit

ATDC. This delay is realised only up to 500 RPM. If you want increase delay - increase this value.

We think that engines with new rotor (firing after TDC at start) not need any support regarding start.

But if you want - you can to use "Lower advance by start %". Note that too big delay (firing at too

high angle after TDC) can impair startability.

Thank you for this new information on ignitech.  I will check it out.
