Check the spark plugs and the carbs.Maybe the carbs need cleaning.
Measure the fuel pump gas supply too (lit per minute)

John Deere Snowblower 1032 won't start. Obvious solution?


First dump the old gas and put in fresh. Clean or replace spark plug.
Put a squirt of starting fluid in the carb. If it fires the ignition system is good. Do this a few times because there is still old gas in the float bowl and fuel line. When the fresh gas gets to the carb it will stay running. If it did not fire with starting fluid the points and condensor will need to be replaced and maybe the coil.

Hi, Anonymous and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting ***** set too low.
8. Air/fuel mixture ***** set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.

My fzr wont start. I checked the air filter, it had gas in but about six months ago it fell over in a trailer so i think it may be from that. The battery is good. It just wont turn over.


My bike has fallen over many times in the driveway lol but always starts after. Was the bike stored for six months? The gas may be bad. I would drain the tank and try fresh fuel. Also check your fuel line. IT May be pinched off from the fall restricting fuel flow. Also check the fuel filter, may be clogged from old gas too.

My gas blower was running fine and it ran out of gas i filled it up and primed it and it will not fire ,, i poured a little gas in the spark plug and it did fire and ran rought for a few seconds


Most always this is a build-up, or manifestation of either flat or old gas, gas with too much oil mixed in, or good old H2O in the storage gas container that runs into the power tool as the supplying tank gets a bit low, or gets shaken before filling-up the blower. Completely empty the blower of fuel. If you are not capable, then have someone remove thewater and/or debris from the carb. inside the blower. or Empyt all fuel in the tank then remove the plug and give it "200" pulls, then replace the plug and give it "100" more. This will sometimes move the trash through if you cannot have it professionally repaired. Replace ALL old fuel with new, properly mixed fuel.

Runs on choke a little


sounds like the carburetor has gummed up a bit, and may need adjustments - or, the fuel pickup in the tank has come loose [i.e.: deteriorated fuel lines] - also, make sure your gas mix is FRESH. if your gas mix is more than 2 months old, dump it

After 1 season it ran great ,slowly died now it wont start


So many possibilities, so little data... <grin>

When you say "clean gas", do you mean that you added "fresh" gas, or that you emptied the tank, and refilled it with "fresh" gas?

Try this:

a. remove the "float bowl" screw, and put a regular "bowl" or pan underneath to catch ALL of the gas as it comes out.

b. if the gas is totally "clear", then it (probably ain't the gas), but... if it's "yellow", it's old and/or contaminated; alternatively, if there's any water (which may appear as a grey-ish liquid) then it's contaminated; also, don't forget to check the gas from your "storage" can, the same way...

c. re-install the the screw, and put some *FRESH* gas in the tank.

d. pull the spark-plug, and clean (or replace) it.

e. prime it, and crank it, and it should start right up.

Wont start after 6 mos. I changed the spark plug, drained & added fresh gas, checked the fuel filter... Kicks over fine. Ran for 4 seconds, then it died. Always ran & started great before.


With a new plug and fresh gas it should start. Check to make sure there isn't a kill switch turned off or that the gas petcock from the tank to the carb is on.

How did you check the fuel filter? Disconnecting it from the fuel line that goes to the carb is the best way, making sure the gas is turned on under the tank. Bleed off a little gas into a can or something just to make sure the filter isn't plugged.

The last thing I'd do is take off the air filter and spray a little starting fluid in the carb. It may start and run several times if there is old gas in there somewhere. Remember the bowl on the carb is probably still full of old gas. After some fresh fuel reaches the plug it should start and continue to run.

(You might drain the bowl on the carb of ols gas before you go any further)

Good luck!

Lawn mower engine runs rough and puts out white smoke


Pull the carburetor and clean it for staters.Be sure to change oil any little bit of moisture in the crankcase will let it smoke white by seeping by the valves and piston rings.Also put a little small amount of dry gas in the gas tank to rid all of the water that may have been left in the tank. I some of this will help you.
