New owner for this engine... No ID plate... Leaky fuel pump on 1991ish Johnson 40HP VRO twin. Previous owner already converted to non-VRO. Pump says 175230. This site says superceded by 5007421/5004562. I see cross-reference to 5007422 on Amazon for good price but says 3 cylinder or larger...
Just bought skiff with above. Starts and runs fine at idle and low RPM. On acceleration it won't go past about 2000rpm and "skips beats". I'm new to two-cycles! See attached and listen closely if you can. Any help appreciated! Thanks.
