I agree, Too much oil in the mix. I run at 40:1 at the moment but have also used 50:1 in the past with no problems.
Drain the fuel tank and re-fill with fresh 40:1 mix.
Tip the bike over on its side to run out the carb.

Good Luck.

Check if you have compression if you dont feel that it is the same as when you bought it then it might be time for a new top end...or at least replace the rings.

Chrysler 200 2013 62te transmission with 3.6 V6 P0729 code and nothing else. Replaced oil/filter 2X and solenoid pack. All looks good. What is wrong?

code p 0729 refers to gear 6 --incorrect ratio===causes ---fluid level---wiring---TR( transmission ratio) sensor /switch---shift solenoids---transmission mechanical fault
the box is operational so no need for mechanical failure to figure in the diagnosis
if you never use 6th gear, it is possible that the solenoid may be a bit rust inside or a wire has failed from corrosion
at this point I would be checking wiring , connections and pins are not corroded and then consider the TR sensor / switch replacement

Jeep no power

which engine option? that be first huh?
sounds like you need a hands one , eyes on mechanic, no?
low engine power, randomly?
gear box, which one? The A/T or the transfer case> 4wd?
is that lost engine power tranny slip or engine power loss
a hands on guy can tell that, in 1min flat. (why not do that)
the Engine light dont lie, it means there was a failure. why not
scan it> and not work blind.
from where? tail pipe end? or somewhere else????
white steam smoke (goes away fast and stinks of antifreeze coolant (sweet)
white burned oil. smells like burned oil and take for ever to disapate.
or black smoke, cause by way over RICH FUELING.

when power loss happens does engine RPM race way too fast.

all this a mech can determine 5min, hands on.
on the internet, may be 50 posts>?

I have a 5L-E toyota hilux that runs fine at idle yhen when you rev it to about 2000 rpm it starts to blow alot of white smoke. I have cut injectors out while the smoke is blowing with no noticable...

i believe the engine is running too lean as if it was running too rich it would blow black smoke If it was blue smoke it is oil related eg valve stem seals,valve guides and or piston rings all of these things will create blue smoke if one of the above is worn out

The smoke come alote frome the pointson pipe

White smoke in the exhaust once the car has warmed up may indicate a water leak into one of the cylinders. Pull the spark plugs and look for signs of water

Craftsman snowblower throttle problem

Sometimes on them the throttle shaft which goes in to the carburetor gets rusty and turns hard. If you can't move the throttle butterfly by hand spray pb blaster around the shaft and move it back and forth to unstick the butter fly shaft.

Mower will start but blows lots of white smoke and dies when throttle is moved to full

sounds like to much oil but you say the oil level is fine. you may want to check the compression on the head to see if the head gasket is blown. if there is a lot of smoke or oil blowing out the oil tube, that is a sign of blown head gasket.

1988 Yamaha ag 200 mono cross blue and white smoke

Hi, Anonymous your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. WHITE SMOKE on start-up can is usually caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers.
2. BLUE SMOKE on start-up is usually caused by failed valve seals. Smoke that is constant while riding is usually caused by valve to guide and piston ring clearances that have exceeded service wear limits.
3. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.
