I have this older Briggs horizontal, I'm guessing about a 3.5 hp, not really sure because at some point the blower housing has been replaced so I don't have an engine code. The cylinder bore is 60mm. I tried to call B&S (twice) to see if they could look up their info to see what a 60mm bore would match to hp. Both times the B&S "assistants" were young girls who had absolutely no idea what they were talking about. One tried to convince me the engine code on this old flathead would be stamped on the valve cover. Good grief.
Anyway, I need to replace the rings and this engine is mounted to a Homelite trash pump and I have to remove the pump to open the case. The pump is connected to the block by four bolts only accessible from the inside of the pump. Furthermore, those bolts are behind the pump impeller. I have been somewhat delicate in trying to figure out how to remove the impeller with no success. I cannot find a service manual for the pump so I have no idea how the impeller is connected to the crankshaft. Is anyone familiar with this pump? Can someone tell me how to remove the impeller? I don't know if it is pressure fitted, threaded to the shaft (CW or CCW) or some other way. I don't want to cause any damage to the pump.
Any help would be GREATLY appreciated.
The Homelite pump model number is 110SU1 1/2-1B, Serial number 50604880
