I had a Bendix on my 64 that did the same thing, I finally disconnected accelerator pump from linkage and primed it manually about 3 squirts, kicked it through with finger on kill button once or twice and then tried to start it. This helped alot. I finally got an S. U. to replace it with and it is beyond a night and day difference! more power, smoother and ten times easier to start. Cylinders burn a much more balanced mixture of lean to rich. The Bendix always had one plug lean and one rich.
Good luck

I would take the spark plugs out and hook them up to the spark plug wires and have someone start turning the engine over. i would either use the side of your engine cylinders or a piece of metal and see if you actually have a spark going from the ignition coil to the spark plug.

1. Damaged or restricted fuel tank venting system (gas cap).
2. Inlet system air leak.
3. Vacuum piston malfunction.
4. Accelerator pump leaking or no output.
5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.
8. Plugged jets or passages.
9. Worn or damaged needle or needle jet.

What should I do with my husqvarna 130BT because I put in too much oil with the gas and it won't start?


First, you need to dump all of the fuel out of the gas tank, Preferrably into a gas container. If you know how much oil you dumped in, you can calculate how much more gas to add. You could also just dump the gas, re-mix some new gas and oil, whichever you prefer.

If you are comfortable doing this, remove the fuel lines going to the carberator and let them drain into a pan. Pump the fuel primer to purge the gas out of the carburator, and then re-install the fuel lines. This might help you get it started a little faster, but its not necessary. You can burn the old gas in the engine at it will be fine.

Next, remove and replace the spark plug. Its probably fowled out with too much oil. Keep a can of carb cleaner and a small wire brush handy, you may need to clean the spark plug a couple times. If it gets too dirty, you can replace the spark plug with a new one. Do not burn Carb Cleaner in your engine for long periods of time, it will damage the engine.

After you have installed the spark plug and put some correctly mixed gas in the tank, Try to start the engine again. There will be some residual fuel in the fuel lines going to the carberator, so you will need to burn off that gas.

If you can't get it to start, try these steps:
Choke off, throttle wide open, crank several times. (or let it sit in the sun for a couple hours) (this corrects flooding)
Prime carberatur, Choke full on, throddle idle position, crank until it fires once but does not start.
Choke half, crank until it fires again or starts.
If it starts skip this step: (Choke off, crank until it starts).
Keep the choke on half for about 10 seconds and let it idle.
Put the choke off and let the engine warm up for a couple minutes.
After warmup, test the throttle to see if it will run at full throttle (it may take some fluttering until the engine is fully warmed up)

Let the engine run at full throttle for a few minutes. The exhaust may be a little more blue-smokey than normal...this is the excess oil burning...totally normal and harmless.

No, nothing else to check. You need to completely disassemble the carb and clean it out. When gasoline left in the float bowl evaporated, it left behind the gummy additives that the refinery puts in the gasoline. This mess has clogged the jets and small passageways in the carb. The reason it runs with the "choke" out is that it is not a real "choke" but rather an "enricher circuit". It has it's own air passageway and fuel metering "jet" in the float bowl.

Good Luck

There could well be a build up of sediment and debris in the main jet to the carburetor. It is easy to get to and clean. It is the brass bolt that holds the lower float bowl onto the main body of the carburetor. To clean it, drain your gas. Remove the bolt and external washer UNDER the carburetor bowl. Clean out the bowl of any sediment and/or water. To clean the brass bolt, use no metal objects. Carb/Choke aerosol spray cleaner will do the job. Pay close attention to the hole in the bottom of the bolt and the very small holes about 2/3 of the way up the bolt. Clean till shiny with holes cleared and reinstall. Your fuel flow problem and shut off condition may be solved.

Hi and welcome to FixYa, I am Kelly.

The symptoms you describe are typical of debris in the fuel bowl of the carb. I am going to assume for the moment that it is a similar to a Briggs and Stratton engine. Engine model type and serial information is what we work with to resolve engine problems regardless of the mower brand. I note you said it was a Scott Bonner SX4000 engine. I am also assuming that you have the 18 inch GreenKeeper like this one:
http://www.rovermowers.co.nz/www/rover/Home.nsf/13a851504c93cb754a257821000cfc6b/$FILE/28045.pdf

I do not have access to Scott Bonner Engine parts or technical data but if you clean out the fuel float bowl and it is still hard to start then the choke function of the engine is not working. Your engine has a "Bowl drain" screw on the bottom of the carb float bowl for removing carb debris or water in addition to a bowl nut.

Most likely due to the throttle cable needing and adjustment so that the choke is closed when choke is selected. Adjustment of the throttle cable is as simple as losening the clamp screw (Do NOT remove it) on the side of the carb throttle control and moving the throttle to STOP then re-tightening the clamp retaining screw. This should allow your choke to move full closed when selected. You may have to experiment with full throttle and STOP throttle control positions with the clamp screw loose but not removed to see which position will give you full throttle, choke and STOP. After each adjustment you MUST tighten the clamp screw to test the throttle cable travel on the the throttle plate. Beleive it or not... the person that assemble the mower made the intial throttle adjustment. It may have never been tested before you got the mower.

If you still have problems.... this is the brief way to start an engine that has choke problems. Remove the spark plug and squirt a splash of gas into the spark plug hole and then re-install the spark plug. Just don't over-do the splash of gas and if your messy wipe off the excess so you do not start a fire. (This method always works but you occasionally foul a spark plug with too much gas)

Thanks for choosing FixYa,
Kelly

It will start on full choke and run for about 5 seconds and shuts off. I changed oil because it was black. It did same thing a year ago and shop said the fuel line was blocked? I ran it for about 25...


first if its a honda,is it a gas/oil mix as the gas/oil mix plugs up quicker than a 4 cycle engine ?even 4 cycle engines that get bad gas i.e. water in the gas will plug up the carburator from rust, white rust(from water minerals) corrosion,dirt,etc.,when its running and just as it dies out,pull out the choke and see if it picks back up in r.p.m.'s,if it does,then you know its lacking fuel from starvation from plugged fuel lines/carb to keep running,then you need to re-build the carburator or you could first try a can of carb cleaner while its running down into the carburators intake,but this is a tell-tale sign of a bad/dirty carb,try this,with a small wrench,pull off the carburarors "sediment bowl" located just ubder the carbs body and carefully unscrew the brass nut and remove this bowl(careful to NOT lose the gasket) and see how moch water/dirt,etc., is in the bowl if theres water it will look like droplets in the gas in there,if you have this contamination you need to clean out both the gas tank and carburator and all fuel lines leading to and from these to the engine

My saw starts and runs "roughly" With the choke


Unfortantaly its awaly the carb with this kind of tool Its a two stroke so you mix oil in the gas then it sits aruond for a couple of years until you need it and the oil gas mixture gets gummy and sticks the neddle valve witch lets the fuel into the float bowl and also shuts it off Try this get some starter fluid get the thing running on choke and spray it into the carb it may clean up some of your problems But the best thing to do is take apart the carb and clean it then it should work like new and its realy not that hard to do and you don;t need any new parts it can be done on a table in 20 minutes

Can't start brisggs & Stratton 21in mower. I


Get some GUMOUT carburator cleaner GAS ADDITIVE. Put about 1/2 TEASPOON in the gas tank and about 1 tablespoon per gallon into your spare gas. The float pin is probably sticking from winter non-use. This will free it ip.

You can also remove the bowl from the carburator and spray everything to immediately dissolve the varnish. Be careful not to lose the pin spring.
