68 f250 390....first start after rebuilding carb and timing gear/chain water pump etc etc. leaks are front part of carb. 4 screws go into. I forgot the name. I do know one screw is broke off in the carb from po. More than likely why its leaking haha.

I dont know carbs at all. Just stating..I read somewhere about turning the adjustment screws clockwise and backing off 1 turn and half. So I did for both screws.. I'm extremely certain is was all at tdc when I put Timing gears together line up dots etc etc.....I do seem to have a issue with the throttle going straight to floor. And not coming back up properly. I did notice open areas on the throttle linkage to carb that seems to be missing things. Does anyone have a pic or throttle linkage? From carb. I did notice behind the carb there is another set of linkages too..any pics could please so I can eyeball what I'm missing...

last question when the throttle is at idle....should the front of the carb with the 4 screws be pushed all the in or pulled out? Mine seems to be all the way in when peddle is at idle position.

So I tried to start her anyway. All she did was pop..I stopped. Tried again...big pop so I stopped..but while cranking before the pops I didnt hear any unusual noises from engine which is a good sign. Because the oil pan was full of water when I got her. Left the hood off for some time..

 

See 9528 in pic. This is the accelerator pump cover. The pump is 9B559 .. its check valve is 9576

 

Yes the accel pump. That's the name. Now I need pics of throttle linkage because I have a feeling something is missing. Hard putting something together that someone else destroyed

 

Upper pic:

 

Oh dear. Not going to be easy haha.

Any thoughts on the back fire should the accel pump be pulled in or out when at idle.

 

Saw this online..not my truck...what's the part. My arrow is pointed to? I dont have that..from this picture. I see I'm missing a few things :-( I'll try my best to Match my setup to this pic.

 

Also I see there Is a spring...where does it connect to? I found a spring but need to know other end to connect it to.

 

Any help would be great..I just want her to run Haha

 

The part with the arrow is called the "dashpot". It slows the return of the carb linkage down, just a little, so that the carb doesn't suddenly stop getting gas, (and the engine die).

 

The accel pump arm should be out from the pump (and carb) while at idle speed. The pump is used when you start to accelerate, so the engine doesn't starve for gas, and the engine backfire, and "stumble".


You can also see that I'm missing the "dashpot" too.

 

That's what I need to see. Where does that big spring go to? I noticed my accel pump was all the way in while trying to start truck. Probably why it backfired.

 

And can I get a pic of the choke plate. The rod that goes to the choke to move the plate isnt connected. I need to see what I'm missing

 

So the accel pump being all the way in while starting..would that be the cause of the backfire? Or setting of the mixture screws?

 

Any pictures of choke side and spring on drivers side

 

Check post #2 spring (no 9636) behind pump pushes out pump.
