locogato11283 Posted December 1, 2008 Report Posted December 1, 2008 call kev at hjr racing...760-815-1316 why would he call this guy to ask for jetting specs?? thats ridiculous. it will depend on temperature and altitude.. but.. i think youll be safe to start at 162 main and 48 pilot. if youre a lot colder than 60 degrees you may consider jumping up to a 165 main and 50 pilot and work from there.

dajogejr Posted December 1, 2008 Report Posted December 1, 2008 165 main (safe because it's cold), CEL needle and 50 pilots. On my 4 mil cub, race fuel, I'm pretty sure I had 48 pilots, CEL needle and 150 or 152 mains. Quote
