Hi Jerome:
Shouldn't be too bad.
You could disconnect the fuel line at the carb and drain the tank.
Drain and flush the carb. Reconnect the fuel line and fill with fresh gas.
If it won't start, pull the spark plug and clean/dry it with a propane torch, or replace it.
Odds are it will be fine.
Cheers.

run fault codes and look for misfire and faulty injectors . Have a pressure test done on the fuel manifold as low pressure will result in your description.

carburetor cleaner.

It sounds like it is running lean. Back out your carbuerator adjustment screws a quarter turn counterclockwise. These settings should be 1 and a quarter on low speed (closest to engine block) and 1 and a half on high speed (farthest from engine block). These are starting points the adjustment may vary a little eigther way. Never adjust for max rpms that is too lean and will cause engine failure. Hope this helps ya.

Hello,
My name is Dane and I am going to try to help you solve your problem. Are you sure nothing is rubbing outside the engine creating the smoke? If this smoke is indeed coming from the exhaust, I would think that your problem has to be in your fuel. You may have mixed too much oil in the mixture or it has been contaminated with water. Remove your spark plug and make sure it isn't oil fouled. If you find it is, drain your fuel and either clean with a wire brush or replace the plug. Refill with properly mixed fuel and you should be good to go. It may smoke for a couple of minutes until the fuel in the lines works through the carb though. No harm done.
I hope I've helped. If you found this information useful, please leave feedback as deserved. Thank you! Dane

if you changed the oil recently you need to use SAE30 and not 10w30. Causes pressure buildup.

turn the choke off. then adjust the throttle cables.

Your gas to oil ratio is 32 to 1. Should cut down on smoke. replace sparkplug at same time.
