Re: 58 Johnson 35 RDS-20 Carb rebuild instructions needed
thanks! I'm wondering if there are carburetor specific instrucitons on where each of the parts I have in the kit will need to go. I'm guessing I'll be going on visual basis and matching new to old.
Nope, not short of the factory service manual. If you go it alone, have a nice clean container (I use a glass cake pan) to put parts in as you remove them. If you have a digital camera with close-up capabilities, use it often. Work slowly and make sure you understand what you've removed and what it does and where it goes. Make notes.
If something has a washer or a spring on it, leave it on as you put it in the parts container. Make notes for yourself. Look at each item and match it with a part in the overhaul kit. If it's not in the kit, you are supposed to reuse the old part. There will be parts in the kit you don't use, which is why you need to do this matching as you disassemble. Carb kits always cover more than one model of carburetor. Otherwise, you'll be questioning yourself about some part you can't imagine where it goes.
Do not remove the throttle butterfly or the choke butterfly or their shafts. You'll ruin the screws or the threads in the shafts.
Pay close attention, make notes, take photos, make drawings to help you.
Nothing non-metallic goes in the carburetor cleaner basket. Follow the directions on the carb cleaner bucket closely about how long to soak and how to clean up after soaking. They have it right.
If you don't have an air-compressor, you still need to blow out the passages. At the auto parts store or hardware store, ask for a can of compressed air. It looks like a paint spray can, and has a flexible tube to help direct the flow. These work just fine. It's not actually air, but some other compressed gas, but it's fine.
There are welch plugs ( convex round metal plugs) in your carburetor. They should have replacements in the kit. Often, you can get away without removing these and cleaning the passages they give access to. Sometimes you can't. If you have to remove them, carefully drill a small hole in them, then pop them out with an awl or similar tool. Once you're done cleaning in there, put a new one in place, then seat it with a flat pin punch about 1/3 the diameter of the plug, giving the punch a nice little rap with a hammer. Not too hard. You just want to expand the plug to seal the opening.
You
can do it, but you'll have some anxious moments, I promise, if you've never done a carburetor before.
Picked up an OEM carb rebuild kit from a local Johnson dealer today. Problem is it did not contain any instructions. Anyone have a copy they can scan and email me?
