So this is realy effective at cleaning out carbon? I already premix with MMO, will it help any?

I ask because my 5/6 ports are carbon'd up, and anything I can do to help loosen them without taking off the manifolds is worth trying. My car is my only car and I really don't currently have the option of taking a day off to strip off the manifolds to get those pesky ports working again.

Edit: I realize that this won't magically unfreeze the ports, the question is more of "will it do any further good on top of MMO premix".

 

OMG...
My car is that happiest I've seen it. you NEED to do this man.

 

the question is: why do you premix with snake oil? it has no advantage over the OMP. use real 2cycle and you'll be good.

 

dont hurt me for being noob, i gota ask questions to learn. so we are talking about putting things in the vacume lines to clean the carbon from the rotors? how can one go about doing so? do you have to dissconnect a vaccume line and put in the Seafoam or MMO or whatever the product is? or do you just put this mix in a certain fluid box and it gets to where it needs to go (yes i know very very noob sounding). and after doing this process you can turn the motor on right after? should you hit redline to help get rid of the carbon? thanks for takin the time to read my reply.

just put the cleaner in a cup and hook a vacuum line up to the engine, hold the throttle open slightly then put the line into the cup and suck up the fluid while keeping the engine revving high enough to keep running.

i wouldn't advise vacuuming up mmo/atf or you will probably have the fire dept showing up at your house and they will not be very happy to find out you were just cleaning the inside of your engine.

typical engine decarbs for rotaries are:

H2O(or water, but i shouldn't need to say that)
carburetor cleaner
a few ounces of mmo/atf (in the leading plug holes, let sit for some time to break up the carbon before starting the engine)
seafoam(i would avoid putting crap like this in the crankcase though, i have already seen enough rotary engines completely missing oil control o-rings to know you shouldn't risk additives in the oil)

 

so seems like water and carburetor cleaner are the safest ones huh. so i fill up a cup of water, hold the throttle open enough to keep the engine running, put the vacume line in, and just let it keep running untill the cup is empty? and if working with carburetor cleaner should i only use half a glass or how does that go? then afterwords should i go drive around, or should i let it sit. thanks for the help bro

which vacuum line?

 

brake booster line. passneger side of the engien bay. the hose it is connected to a decently size metal line on your fire wall to a removeable line on the LIM. i think

 

could you or somebody post a pic of the vacume line please. i dont know wht a brake booster line is.
