Hi guys got a 79 and it will just be goin down the road n it will sputter like its not gettin gas you can pull the choke floor it do anything still not a thing is helping here. i want to know wat are these cut and check valves. and the other check valves. any body know if you can bpass this thing or not??? please need some help here

 

Replace Fuelfilter, if it gets clogged again, your tank is full of **** and needs cleaning.

Clean carburettor nozzles - better yet, rip it off and soak it in carb cleaner for a day.

Clean and lube linkages on the carb

Replace Sparkplugs

Check dizzy for oxidation inside the rotor cap

Those are the basics, if it still acts up, time to get into the emissions equipment.

Good luck

 

Wut?

 

Just thinking it could be vacuum related, but then again I've never had a stock motor.

 

we'll cleaned the tank before replaced filters 2x put new distributor on new plugs last summer Emisions WAt u mean!! rebuilt carb also

but wat is a Cut n Check VAlVE n the otehr to check valves!????

 

emissions equipment i think he was saying change your vacuum hoses and whatnot.

Does it sputter at a certain rpm, can you replicate it in any gear at any speed. All this is relevant information

 

no it is completely random but when you take it out after driving for a bit then it will just sputter n stal i think it's somthin wrong w/ them cut and check Valves CAN ANYONE TEll me wat a CUT AND CHECK VAVLE IS?????????????

 

Where are you getting cut and check valves from? I would make sure all the jets in the carb are clean. Also, the silver restrictor in the return fuel linecould be clogging up.

 

THe cut and check valve is located at the gas tank i have no idea what it does. but can someone tell me if you can bypass it!!!!!

 

firebird I am having the same problem have checked everything else where is the return fuel restrictor located

 

It's in the rubber return fuel hose. You can't miss it LOL

 

kool thanks I'll check that next

 

I think the check and cut valve is the white plastic valve that in the event your car flips over it stops fuel from getting to the engine and causing a fire. Yes you can by pass it. My car doesn't have one anymore.

 

IIRC That's only on the S3 models. It's called the inertia switch
