Car keeps shutting off

[scozz76]

Maybe your engine stop switch is faulty.

Had a similar issue recently, hard to start, once it did start it would randomly cut out after a while. Went through and checked the piston and found scoring on it and the head cylinder. Must have dusted at some point so it was losing compression. It might be worth checking if you have gone through everything else. They aren't hard to replace and not that expensive either.

How hard or easy does the pull start come out, if it comes out with little or no resistance it maybe down on comp.

Also have you cleaned out all the crap under the black engine cover, the poor thing might just be overheating. I had one of those mesh covers on my pull start and my engine would overheat and keep stalling, pulled it off and it was fine again. Not knocking these covers, I think there a great idea I just had issues with mine restricting air flow.

Other things I have had it the cage knocking the choke lever down just enough that it would stall.

also clean all that crap that stuck under the shroud mabe somethings arc'ing in there from all that stuff..jammed in there..

if you have spark then check fuel is getting in ,

I was thinking that it is overheating as the cooling is restricted by all the crap under the shroud. You say it runs about 5min and then stops, getting to hot

if your car ides ok then your carby should be ok, unless its a ruxing one toss that and get a walbro..if it had a air leak it would stall at ldle , unless you compensate it by giving it more fuel ..still you would know as the Low speed needle on 99% of the cars are about 1and 1/4 wound out.. around that mark..

if your car is running and stalling after 5 minutes then i would check the breathe hole in your fuel cap..probably blocked , or the carby insulator block is warped and when it gets hot it expands and lets in air or vaporates the fuel.. seen that quite a few times..

try running with the cap loose enough not to fall of and air being able to get in ..if that doesn't help it change your carby insulator block..

hmm okay so, i just pulled apart the whole thing (fuel tank out etc) and took of the carby, it seems to be quiet clean? like it always gets dirty around the carby needles, but when i took the carby off, the inside looks clean? and it did idle okay, but now i need new gasket

[truckzilla355]

Holy hell that thing is shiny as they come, I take it, its not too old. Might want to start playing, wind the needles out, better rich than lean, start with the high, see if its better or worse. If better leave it or a little more out, if worse wind in a little past ya start point.

What's ya oil ratio, maybe you just had too much oil?

[in rod we trust]

yeah don't worry to much about the inside its fuel so they will always bee clean..

your prob i guess is the thing shutting of after 5 mintues of run time, while ya got it like that and going to get gaskets you might as well change the insulator block..

by the way what brand is stamped on that carby..looks to be a walbro..

is that a crack on the coil i see, also clean around the terminals of the coil if water and grass gets on it it will arc out and cut the engine..

[Seano]

It maybe just range or battery issues with the pico.

[Nichthen]

its a walbro, and i went to the mower shop today and they didnt have any new gaskets...

the thing is, maybe the little hole in the fuel cap was clogged? because it would just die down, like not completely die, like drop to 1/4 of idle for 5 seconds and then die?

You need to get it all back together and meet up with some other baja owners and they will be able to help you out mate.

The dirt on the hole will do that too. Seen some gaskets on fleebay for $8 bucks. And while your at it, change the lower bearings as well. Their seals might have gone to crap too.

Another one is, the shaft that flips the butterfly on the carby might be worn out and can leak from there also. Get some foam earplugs from bunnings and cut them to size and make a hole through the middle and drive it down the butterfly shaft to stop the leak.

I don't think foam earplugs will give you full protection. Because foam earplugs will block all the sounds. If you want to hear other required sounds then you wont hear it. That is why foam and generic earplugs are not good fit to use. You need to use the custom ear plugs. It will fit to your ears. I will share some websites so that you can get more information regarding the custom ear plugs.

When you have opened up the carby replace the diaphragm and check to see if the end of the needle valve has rubber on it. This wears over time and causes erratic idle. While yr at it, cut 3 coils of each end of the metering spring, will give better mid range throttle response, the metering spring mod.

Another way to tell if diaphragm is stuffed is remove air filter and see if any fuel drips out the intake while engine is running.
If it does, shows diaphragm is foobar, and needs replacing and also needle valve.

I do reuse gaskets on the carby if i dont have any spare, but i remove them carefully, slowly and use a pressure tool and put carby in water or petrol to check for leaks under pressure...hope that helps

Ensure no play in the throttle shaft also and are u running the correct temp plug
