7 pin respot cell Problems

[Never_to_old]

This one has me scratching my head

The problem is that I cannot adjust the 7 pin re-spot cell to the right clearance from the stops in the open position.
Re-spot bell crank stop is stopping the cell from opening all the way with the adjusting stop bolt screwed all the way out, bell crank carby link set to 3 1/16"
but the spotting cell is about 4" away from being fully open.
have replaced cell with a rebuilt unit and still no joy.
All new support pins on the table as most were bent.
no other re-spot cells are connected.
The only way I have been able to get it to work properly is to remove the BC stop block ,but I feel this is defeating the purpose.
Any Ideas would be much appreciated

The easy thing to do would be to lengthen the adjustable (master) carbon link near the 2 cell link until it opens fully then adjust the rest of the cells do match.

It sure does seem like the way to go here!

Fixed!

I must have a dumb smart phone.

If TJ's suggestion can't get it far enough open, just drill another hole for the 7 cell link pin/X-washer in the wireway about an half inch to an inch
farther forward in the wireway. I only had to do that once I believe, for some odd reason.

I have a few tables with no bell crank stop block, which was done before I got here some 10 plus years ago, that have always worked just fine. I know it should be corrected but they have ran this long with no issues so no need to mess with it. Maybe something is bent like the 1-2-4-7 wireway, or maybe, and I have never seen this before but I suppose its possible, maybe the ball stud for the master carb link is in the wrong place like a touch too far back. I guess you could measure the distance from that ball stud to the two cell ball stud and compare it with a good table or spare wireway link. If you had to maybe you could drill a new hole for the master link ball stud a little more forward on the link so there is more open motion then re adjust the rest of the cells. If EVERYTHING in the respot cell system on the table is tight and good I can't think of another reason this would happen.

Also the pivot pin for the bellcrank could be loose, the ball studs for the master carb link could be flat or loose especially the one on the wireway, the master carb link could be worn out inside it. All of these things can cause loss of some respot cell movement. Can you make the master carb link long enough to open the cell fully?

Yep, loose ball studs sounds good too. There's too much damage pins can do to everything in that small area. I never understood all the cast aluminum parts in that area. I saw converted B's run forever without the bell crank stop block or the stop bolt and most of them were missing the bell crank spring to boot! These had the long 7 connecting link though, not the fixed 7 cell, and were super easy to set up for smooth operation.

I still have a few tables with the old style 7 cell setup, I really like them and they work very well.

I just finished rebuilding all our tables and half were the old style 7 so i converted the others to the old style ! alot more clearance for the sweep arm .

All old style here

I wish I could do that to the rest of mine!

We converted to the new style with the channel all the way down. The old style has a bad habit of getting knocked off by a flying pin every so often.
Just one more possible call eliminated.

Interesting thoughts on the old style, would be great to see the set up and the measurements , sounds like it could solve a lot of problems.Would be a change to locating wiring problems

Never seen that happen and dont understand how a flying pin could get up that far in the table and knock the link off, and it doesn't hang off the side either. That's an odd one. I've only ever seen them getting knocked off or bent to hell from a table jam.
