Please welcome me and my personal experience to this forum! I just got home from an afternoon of adjusting and readjusting the Perry carb and VP-30 Pump on my ST 3250. Ran good but not great. Engine is brand new and I am running lube content a little high for the large ST but ST suggests the higher lube for break-in. I think this may be the reason for my frustration. I followed the instrusctions to the letter but can't get the "sweet spot" on the high/mid/low N/V setting. I messed with the pressure screw on the pump and need to know how to reset it to original setting. If I can get back to that point then I can cut back on my lube content and start over. I need some help with this and this is what these forums are for. Getting answers...not arguing! I'm all ears! Speedy
