    Default Blast carb expert needed. AE passage not drilled out?

    Hey guys, long story short, ever since I've had this blast it's been extremely difficult to start. Once started it runs like a dream. And once warm it starts back up easily. Running 46/175 for jetting and a superboot. Idle air screw set 2.5 turns out. Timing verified.

    I have suspected the AE as my starting problem, so I replaced it with no luck. Then I started looking into the AE passage to see if it was clogged. I BELIEVE what I circled in red in the picture is the passage where the AE picks up fuel from the float bowl. Is that correct ? And if so, it is blocked by a metal plug which makes me think it was never drilled out from the factory. Let me know !

    Ok guys got it fig red out. Ignore the picture I posted above. Was in a hurry and didn't do my due diligence. However i was on the right track! The picture below is the starter jet, it was never drilled out in my carb (was a metal-blocked passage. I drilled it with a 1/16 drill bit and the bike now starts perfectly.
