Round thingy = Venturi booster, sorry... lol to me it's the round thingy... I had the vacuum advance in the wrong inlet and the correct one was capped off, I switched them, ill try again tomorrow. Also it used to run great when the fuel tank vent was plugged off with a bolt, I took the bolt out you think it's relevant? I'll plug it up and try again tomorrow. I'll also get a FP gauge and check it... Ive checked over the needle/seat situation multiple times and they're brand new... *sigh*
