Ya I know that, I just figured Id mention that neither of them are. Seems to be there are a lot of one liner answers coming from people (not JUST RJ), that are so quick and simple they really do nothing to help the original poster. (dont take offense to that RJ, none was intended)
I think this person was looking for a little more in depth of a response to his question, and I wish I was up to speed enough on jet sizes to give him an educated response. But I dont like to give answers which I dont know are 100% factual and true. But back to topic, doesnt a 350/280 jet difference seem a little extreme to you SEG? Maybe its not, but I always thought jet differences for PTO/MAG and for the center cylinder in triples was usually only about 1 or 2 sizes. maybe a 280/290 split or something. Please chime in and correct my probably incorrectness, Im sure the OP would love it.
