How Much SeaFoam to use?

Hey All -

I just got my new-to-me 73 Honda CB350 and it starts and runs okay (hard to start cold though). Anyhow, I am pretty sure that the carbs should (maybe not NEED to be) be cleaned out. I wanted to try using SeaFoam, because hey, it couldn't hurt. I want to see if I can avoid carb work as long as possible.

So, I know what it does (the SeaFoam, that is), but do not know how much I should put in for the first go-round cleaning. I am looking to put it in both my oil and gas (gas first, though to see what happens). I know that some people use a bit in each tank, but I am looking on how much to add to a 5 gallon tank for an intial clean. Thanks!

Mike

You and me both Brother! Think I waited just too long to add 'Sta-Bil' to my rides this past year and now they're really cranky! :o Just bit the bullet yesterday and sent off for a couple of cans of Sea-Foam myself. The eBay vender posted "one pint treats 8-25 gallons of fuel (average 1 ounce per gallon)" on his page. So either it works or it's pull the carb(s), disassemble, and soak in Berryman Carb Cleaner overnight yet AGAIN. Been there, done that more times then I care to remember over the years, but think you have too?!

Keep the Faith,
LRG

Footnote: Hmmmm, I'm thinking that year of CB350 had about a 3.2 to 3.4 gallon tank capacity. Man, "5.0" would of been great! :D

Here (http://www.seafoamsales.com/motorTuneUpTechGas.htm) is a link to the Sea Foam web site. It shows the mixing process (gas application).

Read the label too. I thought that it had the info on there also. :)

Would put like 1/4 of it in your tank and drive around, see if you notice any improvement

I just bought 3 gallons of gas and put it into a gas can - I will add ~ 3 ounces to the container and use it that way. I will update on the outcome.

It can also be put into the air intake. The can says 1/3 of a oz. I just put 3.5oz into a full tank (3.7gals). I plan to put 3oz into my oil and ride for a hour before I change the oil next time.

Here is info about it:

How to Use SEA FOAM MOTOR TREATMENT
In Tune-Up of Diesel Engines

Fill primary fuel filter with SEA FOAM. Be sure filter is fully primed to prevent air locks. This will clean injectors quickly.
Use 1 pint of SEA FOAM to every 25 gallons of diesel fuel to add lubricity, clean fuel lines, injector pump and remove moisture.
Use 1 pint of SEA FOAM to every 4 gallons of oil to clean rings and other engine parts internally. For best results, use SEA FOAM for 1 hour before oil change. Results in cleaner engines and longer oil change intervals.

When Added to Diesel Fuel Tank

Cleans fuel injectors
De-ices and removes moisture
Cleans carbons as you drive
Diesel fuel conditioner and anti-gel
Lubricates upper cylinders
Stabilizes fuel
Adds lubricity
One pint treats 25 gallons of fuel.


For Anti-Gel and De-Icer

Use 1 pint in fuel tank to 25 gallons of diesel fuel to dry moisture and prevent gelling.
Sea Foam will degel gelled fuel. Start with one pint to 25 gallons of gelled fuel. More will be needed in extreme cold weather.
If filters are gelled, change them and fill them with SEA FOAM.

How to Use SEA FOAM
In Tune-Up of Small 4 Cycle Carbureted Engine Lawn Mowers, Tillers, Edgers, Snowblowers, etc.

Start engine. If engine will not start, check spark and compression. If engine has spark and compression, pour a small amount up to 1/2 ounce into the carburetor throat. SEA FOAM will act as starting fulid and will start the engine unless there is a mechanical or electrical problem. With engine warm, keep on high idle and slowly pour one ounce through carburetor throat. Make sure exhaust is well ventilated when using in the carburetor as fumes will be extreme for a short time.
Pour 1/2 ounce to one ounce into small fuel tank and oil crackcase.
Immediate Results: Same as for large 4 cycle Autos, Trucks, Tractors, etc.
NOTE: One pint treats 8-25 gallons of gas (average one ounce per gallon) or 6-12 gallons of gas oil mix (average 2 ounces per gallon.) Does not replace oil. Use frequently.

For Small 2-Cycle Engines
Use procedure 1 of tune-up of small 4 cycle carbureted engines.
Pour 1/2 to 1 ounce into small fuel tank.
See label on can for exact detailed results for use in each area Fuel Tank-Carburetor.
NOTE: SEA FOAM does not replace 2 cycle oil.

For Engine Storage
For storage, the engine should be thoroughly saturated internally with Sea Foam. Sea Foam can be injected internally through the spark plug holes or through the carburetor with ignition off.

For Fuel Stabilization
Use 1 pint to 25 gallons or (average of 1 ounce per gallon) to stabilize and condition fuels. One pint stabilizes 25 gallons of regular, unleaded and diesel fuels.
Use 1 pint to stabilize 6-12 gallons of 2 cycle (gas-oil mix) fuels (average 2 ounce per gallon).

Common Reasons Service Technicians Use SEA FOAM MOTOR TREATMENT

When your vehicle has a rough idle, hesitates, stalls, pings or has an after run problem – this is often due to carbon buildup.

Your service technician can offer a reasonably priced fuel systems cleaning with the use of SEA FOAM products to solve these carbon problems.

When your vehicle’s fuel injectors need cleaning – this is often due to residue left on injectors from poor burning fuels and contaminants.

Your service technician can offer an inline fuel injection cleaning with the use of an injector cleaning machine and SEA FOAM MOTOR TREATMENT. SEA FOAM MOTOR TREATMENT is also added to the fuel to disperse moisture, clean fuel lines and injectors while driving.

When moisture needs to be removed from fuels or an anti gel or de-icer is needed – these conditions are due to condensation in the fuel tank and extreme cold weather creating gas line freeze or diesel fuel gelling.

Your service technician can recommend the use of SEA FOAM MOTOR TREATMENT in the fuel tanks to dry moisture and cure these problems.

When there is moisture detected in the oil – this problem is due mostly to poor ventilation and condensation. Sometimes, however, there is a bad head gasket, cracked head or block that must be replaced.

Your service technician will diagnose the problem and recommend the repairs. As part of the diagnostics, a SEA FOAM MOTOR TREATMENT can be used in the oil crankcase to cure the moisture problems. A SEA FOAM MOTOR TREATMENT can also be used in the oil crankcase after repairs to make sure moisture is eliminated.

When valve lifter noise is apparent or piston rings seem to be sticking – this is often due to dirty and gummed up oil passages, varnished lifters and buildup of gum, varnish and carbon in the piston ring areas.

Your service technician can offer a SEA FOAM MOTOR TREATMENT that will clean sticky lifters and free sticky rings. By doing this treatment you will be able to determine if there is a varnish problem or a mechanical problem.

To help pass emissions tests – high emission numbers are usually caused by extreme carbon build up, dirty emission control items such as: pcv valve, egr valve, oxygen sensors or bad spark plugs and wires.

Your service technician can provide a pre-emission test service that includes SEA FOAM MOTOR TREATMENT as a cleaning agent to help pass emissions tests.

When fuel stabilization and engine fogging is needed – fuels of today become stale in less than thirty days. Therefore, stabilization and engine fogging are needed when vehicles, lawnmowers, snow blowers, outboard motors, chainsaws, motorcycles, gas in cans and engines are put into storage.

Your service technician can provide fuel stabilization and engine fogging services with SEA FOAM MOTOR TREATMENT.

I just ran some SeaFoam through my Yamaha and it made a huge difference. There's a lot more power, throttle response is much better, and she purrs like a kitten at idle. I used 1/3 in the tank, 1/3 in the intakes, and the last 1/3 in the oil. The intake method is my favorite because I get an awesome smoke show to watch.

Dude! you used a 1/3 of the can in the intake? The label says 1/3 of an ounce! Have you done this in the past?

Well, I used it and it (only in the gas for now) and it IMMEDIATELY made a big difference. Starts, idles, and responds much better now. I know that many are leery of MAGICAL elixirs, but this one, regardless if it is magic or not, does make a difference. Will it mean that I never have to take it apart and clean it? I doubt it, but it should make the times in between stretch out longer. But then again, you never know!

Oh, and a newb question here - how do you go about getting it into the intakes?

Mike

Edit: Oh, and I only used about 3.5 ounces for 3 gallons of gas. Just put the gas in a can, mixed it together, and poured her in.

I did multiple cleanings over a couple days just using a little bit of the stuff each time to make sure everything was out of there. It was very tedious having to do each of four carbs separate but it was well worth the effort.
