replaced intake and exhaust gaskets now it stumbles under low rpms? (1 Viewer)

I had a large exhaust leak at the bottom of the intake at the heat riser plate so I put on new reflex gaskets. exhaust leak is gone
, idles good but a quick test drive and it sputters but I can accelerate out of it.
Any ideas ? timing? fuel filter? clogged carb?

forgot to mention it drove better before with the exhaust leaks.

Possible vacuum leak.
Time to get out the carb cleaner. Spray a little (a little!) in suspect areas.

Does it continue to stumble after the engine has reached “operating temperature” (180 degrees)?

Yes, this. If everything checks out, you may need to tinker with the carb a little. Might have been adjusted to compensate for a vacuum leak that you fixed
