I just removed the carburator main body assemblies from a 1996 Johnson 130 and am not sure how to proceed. I have never rebuilt a carb so I want some advice on what to do next (I do have the Clymer manual).<br /><br />I am not sure if I only remove the parts that I am replacing or do I take the whole thing apart (I want to remove and clean everything)? I saw in the manual that to remove the orifices, I need a specific tool. Is that the case? If I remove the orifices, do I need to install them the same exact way (number of turns, etc)?<br /><br />What about cleaning solvents? I read that automotive carb cleaners may be too agressive. Any suggestions?<br /><br /> :confused: <br />Thanks!

Bubbakat,<br /><br />Thanks for the link. However, do you or anyone else have more specifics about doing this on an Johnson? The info on that site is good but seems somewhat different that the carbs I've got.<br /><br />Thanks again!

Re: Carb Rebuild Help

Hi Freddie.....cleaning carbs is kinda basic. No voodoo involved. Look at the contents of the carb kit. Lay them out and compare them to the parts on the carb. Take pictures if you have to. The first one is the hardest, after that, fairly easy.<br /><br />You can fashion a jet remover from a screwdriver of similar size by filing the edges down to fit the orifice hole. When replacing the jets, don't over torque. When removing the needle valve, count the number of turns that it takes to Gently seat the valve before removing. This will get you back in the ball park when assembling the carb.<br /><br />Set the carb float level with the float bowl gasket surface. This is with the carb main body upside down.<br /><br />Cleaning....it's always good to soak the metal part of the carb in carb cleaner for a while. Then blow out the passages with choke and carb cleaner followed up with compressed air. DON'T soak the plastic bowl in carb cleaner. Just us choke and carb cleaner in a spray can to clean it out.<br /><br />With the plastic bowls, they do have a tendancy to warp. Place it upside down on a flat surface and check for flatness. The bowls can be worked down flat again with some emory cloth on a flat surface if they ain't real bad. When assembling the bowl back to the main body, DON'T over torque the screw.<br /><br />Take your time on the first one. Make sure you get all the passages blown out. The rest will be simple.
