Have a S7 approx. 1971 snowblower (sno - away)with briggs 7 hp. when under load it runs awesome but when not it runs irradically and (sputters and small pops)spits out a small blue flame every so often. Question is, what do I adust to make run smoothly . Carb was (dealer) rebuilt 2 yrs ago but was never tuned after. Any help appreciated thanks

Hi, run it at load and adjust the high speed needle out till it bogs then in till it smoothes out then back it out a 1/4 turn, then do the same under load but at idle with the low speed needle, if this does not help points adjustment would be next.
