Another jetting thread (Blackjack 44s)

I know everyone hates these jetting threads. And yes I have have reached out to jetworks (not turning this into a feedback thread so I'll leave it at that).

With that out they way, I know this is a setup that jetworks recommends and builds for people so I am hoping someone out there has the starting specs art sends his carbs with for a jetworks 771 with blackjack 44s. If it matters, I have a PFP, OEM 155 pump, and an impeller purchased from jetworks with the 771 for these specs.

Currently running OEM 46s but jetworks was trying to steer me towards the blackjack 44s initially. I decided to go with jetworks suggestion since I found a good deal on some to fill in that missing link.

If anyone has specs that would be appreciated.

Thanks in advance

Are your standard SBN 46 working?? If so leave them and pass the hacked up 44s onto another sucker.

They are working, could probably be dialed in a bit but I'm no pro. I have just heard from multiple people that these 44s would be better on my ski, and everyone seems to push to listen to the engine builder so figured I'd try what they recommend.

If I couldn't get a reply from jetworks that was my initial plan, but thought I would ask here too.

Try them out, they will need to be a lot better in order make a difference you can actually feel. Then you will know the credibility of everyone that wants to sell you a modified carb.

You probably are right, but I will always be wondering in the back of my head. But yeah, if I can get some info I'll try it out, if not no biggie.
