Hi !!!. It seems to me that there's a misconception about leaded fuel.
"Leaded" fuel is petrol mixed with nominal quantities of tetraethyl lead (TEL) , in organic and liquid form . It is not (as some people seems to think petrol plus "small" chips of lead on it .
Therefore .. it won't block a stove jet. (if that would be the case... why doesnt block a petrol injector noozle -which is smaller- , and "uses" thousands of gallons of petrol in a car's lifetime ? (not to speak about "wet" electric fuel pumps!)
TEL (aka , the "lead" in the petrol) ,is liquid , mostly volatile , and with the little ammount of petrol burn in stoves absolutely assured not to block/clog any jet. (yes ... I am using leaded with mine ).
Regarding the health issues of "leaded" .. more of the same. Leaded petrol has been replaced by unleaded , because CARS WITH CATHALISTs CAN NOT RUN ON LEADED , not because the lead itself (actually there;s a big hype about the new lead replacement thing being much much more carcinogenic than Lead .
In brief ... for the ammount of fuel burnt in a petrol stove ... theres' nothin to worry about the toxic effects of TEL , neither the jet being clogged . IMHO , coleman indicates "unleaded" just because anything "unleaded" seems more "green , techhie , and ecological" .
