bump

I just realized the one variable we neglected to mention- Filter Type.



After a quick conversation with FatCaaat, he brought up the fact that he had different jetting numbers depending on what type of filter he used.



That would explain why my 141/146 builds with the vm26 were jetted so high compared to others. I was using an open air horn (no filter)
