That’s great, I bet she was pretty proud of that. Hope y’all find the deer you are looking for. I know here in South Georgia they are all over the roads.

Thanks all.
The oil injection system has been deleted.
Could it be the fuel pump?

Is there a suitable carb replacement fir this engine that does not have the accelerator pumps? I'm concerned about getting parts in the future.
That too becomes a bit tricky as you not only need the right carb model, you also have to make sure the jetting is appropriate. That can get a bit sketchy...

Thanks Don.
I found some used 150 HP carbs with the same part number, but without the accelerator pumps.
Here is a comparison:

I would say "off the cuff" that the jetting changes (primarily idle and off idle) were to fatten it up for acceleration purposes (without the accel pump).
More than likely will work just fine on your engine.
