"Learn to like smoke for awhile. Smell the aroma". Pardon the humor. I couldn't resist. Chances are there is oil built up in the crankcase. It is going to take some time for the oil to dissipate. How long? I don't know. It all depends on how much is in there. Cleaning the muffler is no help since the oil burning is coming from the crank not the muffler. If you are careful, and keep a vigilant eye, you could cut the gas/oil mix in half to 64 to 1 instead of the normal 32 to 1. That would mean only 2 ounces of oil per gallon instead of the normal 4 ounces. Let the crank add the rest. This will help burn the crank oil excess, but BE CAREFUL. When the crank drys up you had best not ride until more oil is added to the gas.

It's a 2 stroke. It's supposed to smoke. Yes that extra oil causes alot of extra smoke but I would not run a lower gas to oil ratio. Usually 30 to 1 is a good medium. If it's not fouling the plug then just ride the hell out of it and it will cure its self. If smoke bothers you, then maybe you should consider a nice clean and smooth 4 stroke. Good luck.

The oil in the muffler must be burned out. Try to ignite it with a torch keeping the outside of the muffler hot as the oil burus out from inside. Not fun.

SOURCE: How do i disconnect the oil pump/injection system, Fuel oil ratio

Hi Dan,
Why do you want to disconnect the vital oil supply? If you are experiencing too much blue smoke or plugs oiling you can adjust the amount of oil fed to the engine via the secondary oil pump cable,the one that splits off from the throttle to the carb.
If you disconnect the cable it also stops the oil pump sending oil to inlet, winding out adjuster increases oil screwing in reduces.
As for ratio? trial and error as No knowledge/specification is available for Oil injected engines, poss 25:1 to start but don't blame me if you seize?
Quality synthetic oil is always a must, did you know you can also purchase smokeless two stroke oil?
Good Luck!

SOURCE: break in for rebuilt lower end kx250 2 stroke

Break in is just riding the bike easy for an hour, shifting through the gears w/o high revs. Now go out to the woods and have fun. Change gearbox oil after about 20 hours of riding to remove metal contaminates from the full break in.

Top rating due on this answer! Thanks arenacross91!

Hope you drained the oil and also changed the oil filter.
This problem of cutting off is a carburator/fuel related issue.
I guess the fuel might not be pouring in to the float chambers faster enough.
Try this, remove the air -filter and thn start the engine and as it is about to cut off, block the intake(by your palm) at the carburators and see what happens...taking care not to over block it as the gas may pour out and also flood in the combustion chamber rendering it to shut off due to to much fuel.
If it does respond and stay running thn the problems is tht the carbs are not getting the gas as required and probabley you may have to recheck the float level, the float pin,carb synchro, air-fuel mixture.
Check the pet- c o c k too.
Hope this helps!

I ;have on older homelite super 2 saw. can use the newer oil in this saw with the 50to 1 ratio?


There is no reason why you cannot run any two stroke on todays two stroke oils ( its not like four stroke engines where you use different oils dependent on the age ) however i am not sure i would run it at 50-1 i would be more inclined to run it at 25-1 as it is an old engine.

Have a snapper mower.son put 2 cycle mixed fuel in it and ran it for about 5 minutes. Now wont start. Drained and replaced fuel and changed plug. What next?


the gas sitting in the carb is "still" 2-stroke...there's a bolt on the bottom of the carb...DON"T remove it, just loosen it til the gas leaks out (about 30 seconds or so)...that is letting the 2-stroke gas out and letting in the right gas...make sure the bolt is snug..NOT TIGHT...and giver a few pulls...no choking is needed since it's already flooded from pulling on it...it'll smoke a bit and run a little rough, until it burns the oil mix residue out of the muffler...Now get a Sharpie & mark the cans... 8^)

Excessive white smoke from 2-strokes


HELLO;Im assumeing that both have several hours on them,if so it possibly could be your rings and or the fuel mix your useing. Try and reajust your carbs. ( process of alimination), then run them and see if there is any change. If not, get a hold of me if you would like and we can try some thing else. wwwgreasy@q.com.

Sounds like your running a bit rich. Try leaning down your air/fuel ratio.

Gas/oil mix


Most trimmers are using a 50:1 mix. 2.6oz/gal or 6.4oz/2.5gal. A 4oz/Gal is a 32:1 mix which way too oily and you will have problems of excessive smoke, oil leaking out muffler, carbon buildup causing sticking piston ring or a clogged spark arrestor.

Too much smoke


Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil. There may be an oil build up in the crankcase. Do a 64 to one gas/oil mix for awhile. Watch closely. when the smoke reaches proper levels go back to the 32/1 mix.

Oil leaks


Hi,

Don't worry. The bike builds up a little oil at a time.
This is 2 stroke oil that is unburnt during combustion.
You might be running the bike a little rich.
A mix of 32/36 to one is good for outriding.

You should de-carbon the exhaust and replace the silencer packing. This will also give you some unexpected horse power.

Enjoy the ride !
