Older '03? Crafstman 7HP Mower Throttle Linkage Help

Howdy,
Using this mower as a junk mower and it's taken some beating over the years. The throttle linkage came all undone and I can't figure out what goes where anymore or if there is actually something missing. I was hoping for a picture or schematic that would show the linkage from the gov to the carb. I have a new carb on order instead of trying to fix it but it still has the same auto-choke. Was half tempted to find a carb that I could manually adjust and just run the thing without the throttle cable

So it's the Craftsman 7 HP 21" rear discharge Model 917.378644 briggs and stratton motor. Anyone happen to have one of these beasts that could snap a pic for me?

Thanks much!
Ryan

Not sure what part you need a pic of but this is how the carb hooks up:

geogrubb,

Actually, I think that's the one I need comparing to my own. On the bottom of your picture is the arm. Does anything connect there? Is that the throttle cable? How freely should this move? Mines needs force. Can you picture the rest? Thanks mate!

So I thought I had it but getting absolutely no love on the pull. Pics attached. I don't think I have something setup right as moving the throttle to the start position doesn't actually move the carb in any way, else maybe it's just to provide tention and the carb is always supposed to be choked?

Spark plug is good. tried it in another machine. not sure i'm getting spark though, guess i may need to check wires..

I ordered this carb as a replacement: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Looks to be a pretty good fit. Thanks for the assist.

The problem may be, the tab that the spring is hooked into is bent back, that is the original reason I took the picture, when you run this mower under a bush or something the tab gets bent and you no longer have any throttle control, check the tab and bend it forward at the base. Have a good one. Geo

Thanks Geo. I'll give that a look too. I did pull the ignition coil and i'm getting weird results from it with a multimeter. Seems to give no resistance unless I tip/shake it. Thinking perhaps it's a goner. part on order. guess we'll see.

Saga continues. It was totally the ignotion coil. Fired right up. Unfortunately two events occurred.

1) After the second restart, the housing and pulley exploded -lol.
2) Apparently there is only 1 speed, aka FULL DEATH SPIRAL. Think something is still wrong with the linkage.

So another ebay order is underway. More to come

If anyone has detailed picks of the full linkage for 917.378644 Craftsman or B&S motor Model # 128602-0259-E1 I'd appreciate it
