I have a late 70's johnson 4hp. I bought the motor with a boat and trailer roughly 9 months ago. The engine is very clean, and must have been rebuilt recently before I purchased it.
The first time I took the boat out, the engine worked great for a while, and then suddenly it started to sputter, and then died. It was acting like a car would when flooded. Eventually I got it running again, but it just didnt run right.
The second time I took it out, it worked fine again, but then eventually sputtered out, just as it had before.
Eventually, I realized that I wasnt opening up the pressure valve on my gas tank. On the third go round, I opened the pressure valve, but the motor is still having problems. Perhaps I could have messed up something by not allowing the pressurized gas to escape?
So, now the engine does not ramp up to full speed. It runs ok, but probably at a speed a trolling motor would. Any ideas why it wont ramp up? Occasionally, it will sputter, ramp up to a high RPM, but quickly go back to where it was. This is causing me great problems, because I cant get anywhere on the bigger lakes running so slow.
On a side note, my pull string wont wind itself back up either now, so I have to take off the engine cover, and manually rotate the gearing to get it to wind up before I pull the cord again. Just another problem hopefully someone knows about.
I'm new here, but any help would be greatly appreciated.
Thank you all.
