No, that's a float or float needle and seat issue. The floats may have gone bad, filling with fuel and becoming "sinks", lol, or the float needles aren't sealing in the seats.
Thanks, thsat's what I figured but wanted to be sure. So there is a typo in the guide that might confuse people who don't know any better, like me.The float needle seat is retained by that little screwed down tab, not the float needle. It is as you found yours, and that all looks correct and original. The seat is just a press in fit into the bowl and has an o-ring around it to seal it into the hole. They can often be quite stuck and getting it out can damage it - unless you make up a simple "special tool". This is nothing more than an old shanked bolt with a slight taper ground on the shank end ......

You tap it into the seat and grab it with some vice grips. It allows you to rock the seat back and forth but more importantly, to twist it and break it free .....

And the best part is no damage is done to the seat.
I thought maybe I malformed the top of the needle jet and I did slightly mushroom the top of the main jet but I don't think it will effect anything. The rest of the carbs looked really clean and had new bits put in (from PO) I have another pair that He Cerakoted (the carb bodies) with new jets and pieces. I have another pair on a spare motor I picked up so 6 in total, I figure if I rebuild all of them then I should have a better understanding of Bs34s.I think you'll be OK. If you deformed the washer from beating on it, "dished" it in towards the needle jet then I would recommend flipping it over when you reinstall it so the needle jet will get pulled in completely and seat into the carb body all the way.
Good thing you got it out, it looks nasty, lol. My buddy swore up and down to me that he cleaned and/or replaced all the parts in his BS34s. When I finally had a look at them, they were a mess, lol. He never pulled the needle jets out and they were even more gummed up than yours. And he had plastic floats set at the brass float spec.
Make sure you clean out all the little holes down the sides of the needle jets. Those are the air bleed holes and if plugged, there won't be enough air let in to mix with the fuel, resulting in rich running.
Yeah they are, I have other ones (135? I think) I don’t remember the pilots but I can check when I get home. Good thing I have another pair, I can put smaller jets in and do the Pepsi Challenge to see which one works best, provided I can get it startedAre those 145 main jets I see in your last pic? If so, I think you're going to find them too rich. 137.5's are the biggest I've been able to use in BS34s so far.
From what I can see in the pic the answer would be yes.

drill a hole slightly smaller than the OD of a T15 bit with 6 points of contact, Then tap in the bit, that bit doesn't expand the brass wedging it in ever tighter (near as much as an easy out). the hot tip.

Bonus points it's about impossible to bust off a T15 bit in a brass jet.
