Old Briggs and Stratton Generator. Won't start.

[@JohnWaghorn-i6l]

Intake valve isn't seating properly giving blowback through the carb that's why your getting fuel coming out the carb Adam hope you get it sorted mate

[@whitesapphire5865]

Just as a point of interest, I was watching mustie's latest video today, the one where he's building his Dingo style dune buggy. He's just bought and installed a new carb on that engine, and do you know what? It was piddling petrol out by the gallon. As is often the case with replacement carbs, the float level was not preset, which meant he had to go through again to set the float. I didn't see you checking the float level on this carb either. If you did, then carry on and ignore the next bit. Setting the float level on a Briggs and Stratton carb is about as easy as it gets. With the carb off the engine, and float bowl removed, flip the top section of the carb upside down - the float should hang parallel to the face of the carb top. If it settles anywhere else, it needs adjusting. Adjustment is by bending the tab that pushes against the fuel inlet needle, and you may need to bend that tab to correct the float level. It is imperative that the top of the float is parallel with the casting when held upside down. If the float is too close to the casting, the fuel level will be too high, and will cause leakage as you experienced with yours. Now then....... Let's prove a point? Back to first principles...... Drain the carb and turn off the fuel tap. Then, hoik out that sparkplug splash a drop of petrol straight down the plughole (two stroke is best for that, but not absolutely essential). Put in a new plug, or one that's known to be good, see if the engine will fire up with the carb out of the equation - I'm sure you've seen Taryl and mustie doing this? If the engine starts, it'll run for a few seconds and die. That'll be enough to prove timing, ignition and compression. If that works, then it's going to be the carb at fault. If the engine still refuses to bark off and run for a few seconds, then it's more likely that you have other issues going on - rusty valve seats, incorrect valve clearance, timing being off, faulty points and/or condenser, or low compression. I know you know all these things, but I feel you may need to set out a roadmap for yourself to get out of dark and gloomy woods you're in right now. Don't forget too, you do have electric start on that one, and that's a definite bonus when you're fault finding on a machine like this, and, if you can get it strike up on a splash of juice, you could drip feed it with petrol, mustie fashion, or keep whiffing it with starting fluid, just enough to keep it going, Taryl and James Condon fashion, and to prove the engine is otherwise good.

[@theoilybeard3287]

I'd check the valve clearances before going further - especially the inlet valve. It doesn't take much to do it, especially if you just check they do have something like a sensible clearance. I've have similar symptoms before that turned out to be no clearance at all on the inlet valve.

[@gardeningfromscratch.]

Why not use the electric start that is built in to the genny, it'll save your arm.

[@matnaylor8939]

Fuel pissing out of carb ,float out of adjustment ? .

[@MattKarnes-j5p]

Dear Norfolk man cave I had a very similar problem years ago the fiber pushrod for the points was sticking

[@enginecrzy]

Might be valves? "Easy spin" type starting briggs engines, the cam slightley holds a valve open thrugh most of the compression stroke for a compression release effect. If its worn, there might not be any valve stem end gap causeing the valve to not shut at all. Mine was like this & it kinda threw me for a loop trying to figure out what point on the cam to adjust the valves from, "I dont remember but I have that info somewere & can dig it up if its relevent"...✌👍

[@Brian-1948]

Try using your pliers at 90 degrees to the clip. Too, that fuel pipe needs changing. If the carb needs 2 minutes to fill then thexsipply is not enough.

[@terryraymond7984]

you mean the needle valve ON the float 🙂

[@rogera2513]

Carb is flooded, petrol dripping out the bottom, set the needles to 1 1/2 turns out. Don't use any choke or brake cleaner. Pull to clear and start. once it starts, adjust main jet needle as needed. Is carb link attached? If this not help to start, check the float is level and the float valve shuts off the fuel properly. Good luck!.

[@neilcollin4269]

I've had a sparkplug lose spark under compression try another plug.

[@TheNorfolkWorkshop]

I bought the same carb for mine, I was a bit disappointed when I found out that the needle valve had been jammed in I soon sorted it out though.

[@ludditeneaderthal]

Those spring clip hose clamps are installed because they provide a constant clamping tension, even if the hose rots a bit, or vibration is horrific, or temps swing wildly. A worm clamp (jubilee clip to you civilized brits, lol) can strip by being over torqued, a worn one can vibrate loose due to backlash in the screw/strap relationship, or loosen over time due to the hose taking a set. I loathe spring clamps too, but there is a logical reason they're employed

[@TerryLawrence001]

Those clips are superior to jubilee clips because they continuously put force on the hose no matter how the tube gets with age. A jubilee clip stays at the size you set it and a leak will form as the tubing ages. Just cut notches into a cheap pair of pliers to catch the clips in the jaws. Clamp a pair of pliers in the vise, nose up and drill a hole into the jaws at 45 degrees and straight down. The grooves will catch the clips and they hold on to it very good and you can grip the clips at straight on and 45 degrees or what ever angle you pick.

[@rodsheret9065]

great vid try turning in the mixture screws in half a turn

[@MICMARKMAC]

Valve is sticking 😊blow back coming out of the carb. Sometimes a smallish bent screw driver in plug hole to push the valve back

[@BRI33NOR]

No compression. Valves not seating. May just be out of adjustment. Check spark is not 180 degrees out of sequence. Open choke fully and pull the starter cord again.

[@johnhicks735]

I'm talking about the fuel tank fuel line to the carburetor rubber fuel line hose. It's no good. You'd be surprised how that makes A difference truthfully. Those older engines are.,an where known for that problem to happen to. Good 🤞 luck and Happy Thanksgiving to you to man.

[@tinkeringtaylor3053]

Fuel leaking from under carb when trying to pull start it, is the cylinder head bolts tight 🤔

[@Equiluxe1]

I think that there is some blow back through the carb, when the engine turns over petrol drips from the carb, either the inlet valve is sticking or the valve timing is out or the clearance is wrong.

[@gala1ish]

Just wondering if the generator is connected and drawing power thus loading up the motor when starting.

[@Brian-1948]

Try changing the throttle positon ??

[@VincesEngines]

will it start with a drop of fuel down the plug hole ?

[@TerryLawrence001]

Did valve timing get the better of you again. Second hand motors that have been fiddled could be put together with one tooth out. If the valves where ground but the gap not adgusted, they wont seat with proper dwell time. Just enough to get a quick pop out of it. I love your other channel too! Time lapse drives around parts are cool too.

[@christophergrimes12]

Try setting up the carburettor and turn the screws to one and a half on both Adam

[@TrevorStringer-nb4tc]

you didnt set the float level when you had carb apart getting to much fuel spitting fuel back out of carb on pull over. carb bolts cut slot in top easy run down with screw driver then tighten with spanner.

[@trevornewell4439]

Inlet valve not seating. That's why it's blowing fuel out the carb.

[@electron0002]

Carb is Over fuelling when you pull the cord you can see fuel coming out the bottom of the carb.

[@stevenarmistead3414]

Does it have a venture in it? At 10.01 in the video it just looks like a straight tube.

[@tubeDude48]

When you purchase that Carb., there was a needle set to 3 turns, but you turned it to 2 or 1 1/2. I would have left the Carb. set to original before adjusting. Do a pressure test. Fix the fuel flow. It's to slow!

[@alexgarrod9093]

Have you tried ether? Spray

[@andrewlittle7668]

When you pull it over you have blow back or fuel leak out of bottom of carb ond also i woild change fuel pipe from tank to carb From andy in devon Ps you left the plastic washer of the jet in the side of carb

Nice Adam having nitro cars cluch problem s

[@grandpaseed]

sheered flywheel key?

[@NorfolkMancave]

No mate. Had flywheel off yo do points. Key all good 👍.

[@Trucknbear]

Those updraft carbs can be east to flood the engine when choked. No doubt the gas dripping out is from being flooded from the choke. I would set the high speed setting at one to one and half turns out. I also seen a suggestion to change the plug. I agree.. if it got fouled.. it may not spark regularly. It seemed to me it was getting too much full rather than not enough. I don't think the problem is in the carb. Just too much fuel. It's not leaking when just sitting. If fuel flow was too slow.. it would at least run till the bowl emptied out.

[@Trucknbear]

Since the engine should be governed at 3600RPM. The low speed setting shouldn't ever come into play really.

[@whitesapphire5865]

@@Trucknbear Remember though, this is UK, AC frequency is 50Hz, or in other words, 3'000 RPM.

[@Trucknbear]

@@whitesapphire5865 Ahhh. My apologies.. That o wasn't aware of. However, the low speed adjustment will still not be used even at 3000 RPM. I do appreciate you correcting me . Thank you.

[@johnhicks735]

I really hope that this information will and does help you out with it also. This Jon I know those from the back of my hand. I'd also change that spark plug out to. Sometimes they do not run after being wet either. It's A tail tail sign of A bad.,or possibly weak spark plug to. I know from just looking at the fuel flow coming through that rubber fuel line hose it's not right at all. For sure it's supposed to have more fuel coming out than A trickle flow feed for sure.

[@Herbybandit]

I can't remember, did you do a compression test? Looks like you might need to whip the head of and take a look at the seats, I've had issues with briggs especially not running until I've lapped the valves. And an answer to your fuel line clamp! If you used the correct tool I.e. pliers with the groove length ways, you'd be laughing! Instead of riding the struggle bus. That type of clamp keeps pressure on the fuel line so it doesn't leak as the pipe ages and shrinks, a Jubilee clip will release the pressure causing a leak leading to a fire, that's why you don't use screw hose clamps like Jubilee on a fuel line.

[@terryraymond7984]

I still wonder if its a valve issue

[@johnhicks735]

If that hose is clogged up any at all. It will not allow it to constantly pull in fuel through the fuel line. It's should have more fuel flow than that. It's starving for fuel believe it.,or not Norfolk man cave. Try changing out that fuel line rubber hose. with A different one. Cause the fuel eats up the rubber inside of them when setting up to long. From the ethanol fuel out now days. It turns those hose to try and gummy like texture inside of it plugging it up and blocking off the correct fuel flow through the fuel line to continuously fill the float blow up while it's running. I know you may think it's plenty.,or looks like it to you that is. Those half to have A constant fuel flow feed even under load while it's running to.

[@johnhicks735]

If you change out.,or another term for is called swap out. That rubber hose fuel line that Briggs and Stratton updraft carbureted engine will deliver the proper amount of fuel down to the float blow to continually stay running under load and idling to for yah norman. I got your name mixed up with another KZbinrs channel sorry about that one.

[@daveroberts9431]

Either wrong jet for engine or float is out of adjustment.

[@joostderidder]

I'm thinking loud here ... valve-problem ??? (are they opening/closing at the correct moment) Ignition-timing? Coil partially shorted? Capacitor problems? Compression checked ? You'll get this running!

[@johnhicks735]

That's what is called A low trickle fuel flow. Not A full runout fuel flow.,or known as higher volume of fuel flow all at once and stays that way even when it's running. Just remember to shut off the petcock after running it.,or when you're not using it.
