Have a 600 searies MTD riding mower. Removed deck, can't remember where two tinsion springs re-attach. I think one is for the clutch and the other for drive belt tension. Need a spring placement diagram. Model # 13AM620G120 Any help would be appreciated

I have a Poulan leaf blower with a Zama C1Q carb and have been having trouble lately. It has become very hard to start. The instructions say to prime the bulb 8 times, flip choke lever to full choke and pull starter until it tries to start. This has always worked but now when I try this method it will not start. I smell fuel so I pull the plug and it is flooded and soaking wet. I ordered and installed a new carb kit (new gaskets, diaphrams, needle, spring, and primer bulb). However I am still having an issue. I pulled the carb while still attached to the fuel pickup and return lines and pressed the primer bulb and there is a substantial amount (6-8 large drops) of fuel coming out of the carb venturi. I am pretty sure this is not how this is supposed to work. Isn't the primer bulb simply there to get fuel from the tank to the carb? It is not supposed to be "injecting" fuel into the cylinder is it? Any help would be appreciated!
