The other day I was asking about my 127 and what would cause it to carbon foul the plug so soon after cleaning the carbon off the head and piston.
I had replaced the blown head gasket and installed a new plug only to find out the the 12hp motor was blowing a lot of smoke out the breather. So I took the advice mentioned here about adding MMO to the gas to see if it would free up any stuck rings which may be the cause of the blow by.
Well after only a 1/2 tank of gas with 5oz of MMO in it the plug fouled out, I removed the plug and cleaned the oily carbon deposit form it and reinstalled the plug.
Today after starting it and taking it for an hour ride through the woods at full throttle and low speed on the hydro lever here is what I have comming out of the exahust pipe.
No smoke, which is good? right?
and here is what the breather looks like
again no smoke visable, good so far ?
I am hopeing the the MMO loosened the rings and my oil comsumption/blow by will be greatly reduced. I will have to keep an eye on it the next few times out.
Also here are some snap shots of the seat I replaced the old worn out one with.
All the way back.
All the way forward.
Nice comfortable seat to ride around on.
