Distributor problem

[82-70 Elvis]

Since distributor fine tuning is definitely not my forte', I have decided to seek the help of all of you knowledgeable folks on Bowl-Tech. I've got two distributors that have developed a "stutter" going from the 2 pin to the 4 pin? They will hesitate and kind of jerk (stutter) when making the 2-4 move, thus causing occasional pile-ups around that area. The problem is not what I would call consistent, in that they will sometimes make several runs without stuttering, then all of a sudden...ssstttuuuttteerr [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]
I've checked and tried everything that I know (serviced clutch, rollers, etc.), but nothing I've done so far has seemed to help the problem.

Any help on this would be greatly appreciated!

Thank you. Thankyouverymuch.

Re: Distributor problem

Hound Dog-
If it's only in that move (2 to 4), I'm going with distributor cam wear or cam roller failure.

Maybe the dist tubes or rollers are damaged but surely you would've noticed that right away.

Maybe the dist drive housing weldment 27390 is notched from wear, and you get the "stutter" when the balls can't climb out of the notch.

Good luck,
Chaddy

Re: Distributor problem

Beat me to it, after the clutch I was immediately thinking cam or cam follower wear. Thatd be the next place to check on my list

Carriage rubbing the belt runner where the guide wires attach to the carriage.

Re: Distributor problem

Chad posted this possible solution on another thread, having to do with a "swinging distributor".

I've seen the 4 pin shoot right over the bin's pocket into that empty space ahead of it, and on to the table below. Chad said:

>>"The Distributor mount is not level.
To level it, hang a plumb bob (even a kicker roller hanging from a string will work) next to the mount where it bolts to the pinwheel guard. Loosen bolts and adjust mount until it is parallel with the string.

This is more difficult if you have the old-style mount (casting and tube instead of channel).

If the problem persists after plumbing the mount, the distributor post may be bent. If that were the case though, I'd think you'd have more problems because if the post is bent then the distributor can't turn on it very well, can it?

Sticking a distributor tensioner spring or kicker spring inside of the safety link spring is an effective short-term solution, however.<<"

Possible solution?

IMO, Chad's the guru!

Re: Distributor problem

Some distributor belts will cause this problem when going from the #2 to #4 I call it belt stall you will see it a lot when using Rough top belts like the black one Vantage sales.Also I have seen the problem with the blue belt that A-1 sells.

Stuck -
Well thanks, I'm honored. But truth be known, I'm not that great. Good, but not great. Now on the other hand, in no particular order, 82/70 King, Sponge Bob, Jimmy Jam, Masternut, Kat, Lampie, Noolio, some other people I'm not thinking of presently so I apologize. These are the BowlTech people who will identify your /70 problem, give you the best way to remedy it, and keep it from happening again.

By the way, your pal Vinson isn't gonna be happy when he reads what you wrote above. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Pull both springs(safety and post) of and use gravity to adjust the dist. mount bracket.
If the bracket is not straight the dist. will go to the left or right.

Re: Distributor problem

Chad,
I apologise. You're right. I am remiss in recognizing the other guys. I've lurked here LONG before I ever posted, and all you guys, 82/70 King, Sponge Bob, Jimmy Jam, Masternut, Kat, Lampie, Noolio, and you said "These are the BowlTech people who will identify your /70 problem, give you the best way to remedy it, and keep it from happening again." Oh, so right.

Then you said:
>"By the way, your pal Vinson isn't gonna be happy when he reads what you wrote above.<"

Oops! Sorry Vinson! No offense intended! LOL. I've invented a device to remove foot from mouth. Using it now...thhhh-pop!

I still love the two screwdrivers idea. Fun stuff!

Re: Distributor problem

I realize that I'm a little late chimming in on this discussion about your dist problem, but TBC hit it on the head. If you're running rough top belts, they will cause the pull- back problems you described. Put the original white belts back on, with proper length, and your problem will go away.

<font size="2" face="Verdana, Helvetica, sans-serif">Replaced blue A-1 belt...problem gone! Thanks TBC, and to everyone else who responded as well. Never would have thought the belt could have caused my problems [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] . Sorry it took me so long to respond back to you all, but I was waiting for my new belts, after everything else I had tried failed to remedy the problem.
