Need more outta my johnson, doh

[fishcracker]

Subject sound a little funny...oh well.

Sunday I took out my 1974 johnson seahorse and it started 2nd pull after replacing the coils last summer and having it sit since then.

My Q is It seems that it just won't give my the same amount of power as it did the last time it ran. It's like at full throttle it kicks back down a few rpm. I pulled the plugs and there is spark but the plugs look 'wet'. Too much fuel?? I have played with the high speed mixture setting and have the motor running lean which it seems to like the best. Any advice? I am going to change the plugs since I do not know the last time they were changed. I have had the motor for 1 year.

Could ya' post a hp or model number fishcracker? Couldn't find any previous post with the hp in it.

Be careful how lean you run the engine. If you can get hold of some Sea Foam gas treatment, that may help. You may have some gunk in the float bowl.

Have you checked out the FAQ for needle setting by Joe Reeves? It's a good read. Here's the link.

Well put in new plugs and adjusted the high speed needle valve and she runs tip top.
