I am having trouble geting up to full throttle. I replaced gas tank, fuel line and primer bulb. I also bought two fuel pump carb rebuild kits. Anyway I only rebuilt the fuel pumps and noticed i didn't get a new diaphragm in the kit. The old one is kinda bowed or bulged the other one was alot flatter. I used it anyway and a slight improvement in topend. but it's not where it should be in speed. Does the diaphragm sound like the culprit? Also this <br />1978 50hp is a real gas guzzler, was this model known <br />for that trait? Thanks
