I purchased a 79 25hp evinrude 25904 that had been sitting for at least 4+ yrs. I bought a carb rebuild kit and some carb cleaner....and replaced what parts I could get to ie... float and the "thing" that hangs from it....I sprayed cleaner everywhere I could reach. There are some parts left over that I'm guessing went under the "freeze out plug" looking things...but not being sure what I was doing, I didn't attempt to take them out. I'm not proficient enough to do that and the nearest mechanic that I know of is over 40 miles from me. So I did what I could and hope it worked.
I replaced the plugs. No noticeable fouling present on the old ones. I'm getting proper spark from both....1/2" on both. However, the bottom coil is somewhat questionable as the "waxy" looking stuff has run down it some. I checked compression and I'm getting 110 on top and 105 on bottom. I replaced fuel line on tank and on engine going to fuel pump and carb.
Here' my issue: engine starts decently well and will idle. Goes into gear and goes well until getting above 3/4 throttle....then engine starts cutting out and will die unless I pump the bulb on the tank line. Perhaps it's a fuel pump issue or that "waxy" coil??? Perhaps even dirty carb???
Any suggestions what I need to do?
