**** smoke sounds bad, If what you meant was white smoke then I know what is going on with the mower. The white smoke is from the extra oil in the cylinder head. There are tow causes for this. #1 the engine rings are worn and will not prevent the oil from running into the combustion chamber as the engine sits. #2 the carburetor is leaking fuel into the oil and thinning it out. This thin oil bypasses the rings easier and drives the oil level up too. I would recommend a carburetor rebuild. You can get parts from a local dealer like www.arcolawn,com Good luck have a toroZ5035 mower 90 - barterjoe_64.png

You probably may have valve seals leaking, or an internally vented carb which is now flooding and sending fuel into the oil, this needs addressing straight away as it will cause damage to the engine as it thins out the oil.

1996 Kawasaki VN 800 Vulcan Classic hard to start when cold

Hi, Pete before you start it in the morning, pull the spark plugs and sniff them. Do they smell like gasoline? Are they wet? If so, you may have fuel leaking past the needle and seat in the carburetor and flooding the cylinders.
Use a voltmeter on the battery an hour after you shut the bike off. It should be at least 12.6 volts. Check it again in the morning. It should still be 12.6 volts or more. If not, something could be drawing current when the key is off.
If it's a carbureted bike and the ambient temperature is warm, you may be over-using your choke/enrichner. Try cranking it with the choke turned off first and then try half-choke, and then full choke. If you start with too much choke it will flood. After it starts, shut the choke off after 15 - 30 seconds and then use the throttle to keep the bike running until it warms up. Over-using the choke will soot up your spark plugs.
A fresh set of properly gapped spark plugs can make a lot of difference in how easily a bike starts.
Engines need a richer fuel mixture when they're cold. An intake leak can also cause hard starting because it leans out the air/fuel mixture.
After you get the bike started, spray some WD-40 or carb cleaner around the carburetor intake manifold seals. If the RPMs change, you have an intake leak.

The mower was putting out white smoke and then it was choking out. Now it won't turn over/ start.

There may have been too much petrol going into the engine, possibly caused by having the choke on. Ensure the choke is not engaged, and then try to start the mower again

Kawasaki KLR 250 takes about 12 goes on kickstarter to start engine from cold. it seems to make maters worse when you use the choke. so i start it without choke but it takes a lot of kicks to start it

I have a riding mower that is similarly stubborn; try this which works for me: - Full choke for one cycle - No choke but full throttle for the next try; it works for me/it.

I have a Craftsman Yard Man 6.5hp push mower with a Briggs & Stratton engine. The engine starts and runs fine for about 30 seconds or so then slowly dies out. It turns over slower and slower until it...

Have you checked the choke that it is off after you get the engine started,the black smoke is definitely from the choke, if you take the carb off and check that the needle closes when it should,as one can easily do an adjustment by bending the float/tab,rgds

Bike wont kick start or idle , it will coast

first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.
