I had a clogged idle jet in one carb.  Begging, pleading and verbal abuse got me nowhere.  I was dreading tearing it apart, so I dumped some Seafoam in the tank and rode it around... 10 short miles later, it was running just like new!     Yay Seafoam!!  

I will admit that I did put more Seafoam in than recommended, but I am not going to argue with results!

(I had performed significant diagnosing before I was finally able to narrow it down to a clogged idle jet.  Mid jet on that carb could have been gunky, too...  Everything else was fine: compression, spark, vaccuum, etc.)

Love that stuff.  It'll break down anything.  Its the only stuff I've found (and I've pretty much tried it all) that will break down heavy carbon deposits on intake valves and in combustion chambers.  Matter of fact, I just bought two more cans this morning.

Water will break down carbon deposits from the engine.
After its nice and warm, spray water into the intake with a dropper or a squirt bottle and if you have the airbox, remove the filter and squirt/spray/mist away. High idle so it doesn't stall and nice hot motor. Watch the black billowing smoke. Then after its done, ride 15-20 mins and change the oil.
Cool.

Where do you get Seafoam?

I got mine at the local AutoZone.

Northern Tool just started carrying it in large large quantities.
Cool.

Indeed, it will steam clean the combustion chamber.  That's why its so easy to find a blown head gasket on a watercooled engine.   Unfortunately it wont clean the intake valve or intake runners very well though.  My Mustang has a butterfly valve in one of the intake runners that opens after 3250 RPM that commonly carbons itself closed.  Seafoam to the rescue!

Is this stuff fuel-system cleaner??  I need something heavy-duty for my F-150.  My mechanic friend has "TNT", but he charges like $50 a pop, and it's basically jet-fuel from what he told me, I guess it burns the stuff out.  Anyway, wanna try something on my own before I run it into the garage.

yes and you can also let a vac line slowly suck it up to do a even better job, but pleas read the directions, as you can hydro lock it fast if you not carfull. be really for a lot of smoke.

run the engine till it hot
run with the seafoam being sucked in
when you start to see smoke shut it off (after removing the can from the vac line) for about 5 min
then start and drive or rev it to clear it out, driving it is cooler

it can folw plugs so be ready to replace one if the idle gets ruff, and change the oil as well as there is a lot of corbon loose now.

jet-fuel =  diesel.  I have heard of using diesel to flush the crankcase, running it through the intake or fuel system would be bad...

Jet-Fuel = Diesel???  I'm no chemist, but I know diesel in fact does = kerosene (+ a little dye so the man can tax it).  Therefore, we have a kerosene air-force??  Somehow I wonder if we'd be winning the war if we in fact used jet fuel in our planes....hehehe....Just kidding brother... what do I know, I took engineering in school, hated chemistry....

Jet fuel is simmilar to diesel but it's basically kerosene. Of course diesel, kerosene, and jet fuel are all very simmilar and on most engines/heaters/jets can be used interchangably but it'll probally foul up your engine rather than clean it. Sort of like running two stroke gas in a four stroke engine. Yes we do have a Kerosene powered air force, in fact almost all of the military vehicles including trucks, planes and tanks run on the same stuff.

The Sea foam is the only carb/fuel system/crankcase cleaner that I've tried that actually dose any good. It's a little expensive at $7 or so a bottle but it works. Supposedly it'll clean your crank case too. I don't really like the idea of using very much of it in the oil but I've started adding a few ounces to the engine oil a couple days before I change my oil. I have no way of telling if it works but judging by how it works on the intake and combustion chamber it probally dose.

Definatly use the Sea Foam before paying a mechanic $50 for probally the same stuff.

Kerosene: CH3CH2OH
Diesel     : C10H22 to C15H32
Jet Fuel  :  

Although I couldn't find a formula for jet fuel, I saw it referred to as "aviation kerosene", and that it is made from a varying "mixture of petroleum hydrocarbons", just like the diesel and regular kerosene.  So why can't I fly my space heater down to the store to get some Twinkies???  Maybe I need to rejet it?.....heheheehee
Learn somethin (almost) everytime I'm here...

We use kerosene in all of our 4,500 hp gas turbine engines at work.

Seafoam is kerosene+ammonia+methanol (or ethanol).
Add in MEK and you get carb cleaners like Gunk.
The marine clean thing that POR - 15 sells is Sodium Hydroxide AKA - Lye.
Cool.

+1

jet fuel (jet-a)
kero
diesel

all about the same, in aspect of being kerosene

but form the list above the major diff is this, sulfur content.
we run jet-a in all the tugs and trucks at work (as thats they carry)

the f-450,the Volvo 10k refueler are turbo and they do not smoke at all, the tail pipes are clean as well, as in no soot

i hope that this is what will be coming in the future of diesel, low sulfur = more power

When is the diesel GS (or would that be GSD) hitting the states?  I'll be in line...hehehe

G5

yea they are diffrent for the frezzing and btu points
