1964 18 horse

I started it up and while it runs it clunks. Purrs fine then clunk and it does it over and over. The shifter is weird also but that i have figured is just the shift linkage. It looks like this.





I want to know what this clunking could be. Could it be a bad plug? I want to get on the water asap. The shifter problem I plan to take to the local shop.

Re: 1964 18 horse

ok thanks i'll try that. My father and I have figured that the problem with the shifter may be a bushing. Could this be the problem? You can't view it from the pictures and we also thought that the noise may be from the engine not being warmed up?

Re: 1964 18 horse

ok lets figure out if it's the gears of the engine. have you had it in the water, or are you testing in a tank. if its idling and running fine an then sort of misses a beat, coughs, it's the carbs.

Re: 1964 18 horse

I took it out on the water this weekend, and after it gets warmed up the clunk goes away. The shifter problem I haven't had fixed yet because it doesn't jump out of gear or make any noises. The clunk while warming up happens in all gears so its not the gears clunking I know that because once it warms up it stops. I'm also wondering can I just buy some carb cleaner and clean it out without taking it off because I really don't want to mess with it all that much. Like the jet spray out of a pressurized can?

Re: 1964 18 horse

The gears were replace last summer because of a lil mishap with leaving the motor in the water to long and old seals or something like that.

take the carb off, clean it out and reassemble with a rebuild kit. it's a very simple carb, also a lawn mower carb.
