I all. I picked up an early model white and blue Honda 10 horse with the points ignition about 10 months ago. It has ran before full speed fine but I have to ease into it sometimes to get it to rev up. Other times like today, it idles poorly and was backfiring and popping out of the carb and a...
Hi everyone. I recently picked up this 71’ Evinrude Fastwin 18 Horse. It won’t stay idling for more than 30 seconds. But it will rev up and stay full throttle fine. Took my 14 ft Gregor with 3 smaller people at 24 mph. When I come back to idle, it will eventually die. At idle, it will begin...
Hi guys. I think it might be appropriate for me to add a conclusion to my motor. First off, I didn’t get any notifications that others have replied so I am sorry for overlooking. I would like to thank everyone for their help! It means a lot to know that there are helpful people here. I believed...
Have you checked if your motor is firing on both cylinders. If it won’t rev up and hard to start and idle, it could be a bad condenser. Try removing a spark plug wire from the spark plug while running. If it shuts off try the 2nd one. If it has no effect, then one cylinder has no spark. It was a...
Hi everyone! I was wondering if anyone knows anything about a Gamefisher 25 Horse. I have the chance of buying one for $200. The owner claims that it doesn’t have spark or when it does, it is very weak. He hasn’t seen it run before. It looks to be a 90’s 3 cylinder possibly. I went and looked...
I redid my 1980 Sea King 15 Horsepower with the impeller, fuel pump, and cleaned carb. Mine’s does that hesitation and then jumps to heavy throttle too. I think that they must all run like that. I bought a carburetor from allstrand marine I think and it was supposedly new or rebuilt. It looked...
That carb setup looks different but the same rules may apply as that video. That top screw that touches the mag plate should be lined up with the tiny line on the mag plate in the fully closed throttle position. There should be an idle screw on the other side of the engine that connects to the...
40:1 will be great. It should be rated 50:1 from the factory but the extra lubrication is recommended. If you did research on YouTube you might’ve found this video. It helped me greatly getting my 15 HP running!
Not sure what your reed valves look like but on my 1980 Chrysler Sea King 15 there were little metal flaps on the fuel pump diaphragm on top of holes. Slightly different animals but still related. The holes should be completely covered by the reeds and the reeds should be flat not warped. And...
I think it was 170+? I know that the other surfaces on the head away from the spark plugs were still over 200. It definitely doesn’t want to push much water out at half throttle and above, but reverse and neutral are completely fine. Something with being in the forward gear is messing with the...
Hello everyone. It’s been a month. I found that the passages and the pickup tube all seemed to be fine. I replaced the driveshaft seal on the impeller housing. I added a new wear plate. Still no luck. I’ve found the motor pumps good water in neutral and reverse but for some reason giving...
The Gamefisher/Chrysler/Force outboards, I’m thinking yours is, has to be deep enough in the water to pump water. Where the impeller housing is on the motor is where the water level should be over. Not sure if you overlooked this but just a suggestion.
I took apart the exhaust housing and didn’t see much. I shot a water hose through the engine prior and soaked the jackets in vinegar overnight. It seems fine. I’m not sure what else could cause this problem. The bottom gasket at the bottom of the motor looked fine. The waterpump seems strong...
I took some pictures of the head though they’re not the best, I didn’t see anything substantial in the head. I’m thinking that I might remove the exhaust plate on the side and look through there?
