i have vm33mm. smoothbores.
I would like to order larger needle jets (emulsion tubes). I now have # 261 size # o-8. can u tell me what size I need to order. i would like to get back up to needle clip position #2 and have the same amoult of fuel flow that I currently have at needle position #5. does that make sence? Is there a mathematical equation or rule of thumb that tells me that 1 needle clip position increase is equal to x mm. increase in the needle jet ?
