Tecumseh h70. Old style carb, series one I think.  Ive been playing with this carb all morning. The points have been cleaned and gapped.  I cleaned the carb good and did the pre-set adjustments (1 turn out for idle)(1 1/2 out for the main). Then I did the final adjustments with it running, warmed up. It idles great, and revs great, but when Its at idle and I hammer the throttle, it bogs and bakfires out the carb. sometimes flame and sometimes no flame. am I too lean or too fat?

Thanks in advance, 70 Chev

Sounds to me that it is too lean. Make sure that the little hole in the main adjustment nut is clean. It is hard to see but it is in the smaller threads towards the top of the nut.
