Does your stoker have a slip collar over the drum gear or a slotted crank on the gearbox? Depending on which style you have, you can either change the number of teeth exposed to the drive pawl or change the "stroke" with the slotted crank. In both cases, you check the feed rate by shutting the power off to the stoker and turning the input shaft to the gearbox by hand. Make the ratchet go through a full stroke and count how many times the check pawl clicks. If my description isn't clear I can probably take a video of mine.

I am not sure about what you are saying, there are two dogs , one to the right side I can move half way around to the left but looks like it does nothing, the other dog moves the coal screw . it is connected with a carter key at the end of the gear. I just set the base in the cellar and I wanted to see if the motor was working.

That is not an EFM 520 stoker...it is one of its bigger brothers. :) S30 stoker perhaps? Can you read the tag on the blower housing or the info plate above the fire door on the boiler?

The crank on the gearbox is slotted...you loosen the bolt and change the position to change the "stroke" of the ratchet. Can you determine how many teeth it is set at currently?

ok, I didn't know that as I was told it was a 520, so is it better than a 520 or what do you think the difference is? I will look at the blower and see what it says.

I circled the slotted crank in the attached picture. There is a bolt on the back side that gets loosened, and you can then slide the pin within the slot to change the feed rate. I wouldn't mess with it until you determine how it is currently set...might be fine the way it is.
