car goes pop

[4eyepride]

im having problems with my car's engine is a carb by the way anyways when i hit the gas sometimes the motor goes pop it makes a pop noise what can it be?? car does run fine except for the idling too high what can that pop noise be though????

Pop out the exaust or the carb? Some carbs have "flat spot" were they dump a little too much fuel for a second and can cause a back-fire. Are you stomping it to the floor? Try to ease it down smooth but fast instead of stomping it.

Timing off??

Could be many things. A pop is usually timing related. If you mash the gas to the floor, get a hesitate then a pop or sputter, it's probably running to rich.

Also could be a sticking valve, depending on the mileage...

Take a little base timing out of it and see how it goes. Maybe invest in a new carb?

Could be many things man, check your timing, pull your plugs see if the motor is running too rich or too lean, check for vaccum leaks.It could be a number of carb related issues. A problem like your having can't be solved by somone telling you what it is on here. You gotta cover all your bases.

could it be that because the fans are always on, the car wont past 160 degrees is always running cold and the carb is idling at 2500 all the time could that be it
