I have a johnson 48 special on Lowe pontoon boat. ran great last year & this year up untill last few trips out. starts great. idles great. very slow speed is great also but if you give it just a little more fuel it will spit & sputter like it's running out of fuel or flooding out, but you can increase speed just a little bit more and all is great again all the way to WOT. bulb doesn't pump up hard, on some pumps it will start to get hard then soft again, doesn't stay hard. just wondering where to start looking and what to look for. other than at this one throttle position it runs great. thanks in advance for any help. by the way still use same oil and get gas at same station as always.
