2003 magnum330 carb?? problem

I have a 330 magnum that belongs to my neighbor. It starts and idles OK.
It doesn't want to Run right under load or at full throttle. I took the air box and air filter off, and If you put your hand over the intake while it is running and restrict the air flow ( I think this richens it up) it seems to run better.

I took the crb off after reading all the posts thinking the carb was dirty.

It is clean thru out.

The rubber diaphragm on the top of the carb?? what is its function???
If it would have a pin hole leak would this cause the problem??

I sure could use some help here.

thanks

I still have the carb off. I will go over it again. Is there a way to test the diaphragm??

I tried to view the picture in the carb sticky file, but I can't see it load it or download it.

Is it anywhere else??

I would like to see if I am getting alle the areas mentioned in that carb file.

Thanks again

an air compressor is your best friend when looking for a leak in a carb.Id do it with the gas boWl off to test the needle and seat though
