fuel or ignition

I have an international 454 that has a miss/sputter. If choking it takes the problem away does that always mean a fuel problem?

Sounds like fuel to me. A leak in the intake manifold can do what you describe.

Most likely the gas tank outlet to the sediment bulb is partially clogged.

Not always. I had some bad condensors mimic that same problem.

Also it could just need the load needle opened up some more.

Are your points opening far enough?

(quoted from post at 15:41:19 04/25/14) Are your points opening far enough?

Yes I did check the points. I set them to the manual recommended ( cant remember what it was)

I did pull the bowl off and the flow seemed good. I may check it again though that was my original thoughts.

Is there more than 1 needle on that carb?

It could be the mechanical advance froze up in the distributor not advancing the spark.
It could be a vacuum leak.
I wouldn't spend the time adjusting the points. If I went that far I would replace them.

I pulled the line off the carb, cranked and get about an once and a half per splash. I think that should be good.

Have to look at spark now.
