I have my 1954 Ford 6 cylinders that ratatouille while driving slowly it as misfires and farts when decelerating, I checked my spark plugs OK ! what could this be coming from??
Check your timing and make sure your carb isn't overly rich. What carb do you have? Could be a bad power valve or needle and seat not closing off properly.
Could be clogged fuel filter or carb. Most likely ****ed up some **** out of the tank when it ran dry
my old 6 cyl had a hole rotted through the intake into the exhaust. started poorly but ran. could not see the hole til i took carb off
Possible bad condenser, most are now offshore made and have been causing issues like that and more on several Ford Forums, in most cases putting the original OEM Ford condenser back in will cure the problem. NEVER toss an original !
This is a original condenser !!! I just think it's **** in the carb, I'm going to clean it, put a fuel filter in and I'll see!
I changed my fuel pump and it works well with the new electric fuel pump! Last question! as soon as I put my original air filter it grazes (it to grates) and when I remove it it goes better! What can it come from?
I think I found the problem! the electric fuel pump is too high compared to the tank! The gasoline does not stay in the fuel filter when I turn off the engine and I have a slight break in the fuel hose! It could come from there!
I found another problem on the Ford! the spark plug cables, because it was running on 5 cylinders instead of 6 cylinders , I put my old ones back and it goes round, only it backfired to deceleration! What can that come from? Big shot in the exhaust!
Usually backfire in the exhaust is caused by unburned fuel being ignited in the hot exhaust instead of in the cylinder. When we were kids we used to turn the key off on deceleration then turn the key on and get a huge boom when the fuel that was now in the exhaust (from the turning engine without ignition) ignited. Was fun till you realized the muffler was now exploded from the blast. So, anything that momentarily interrupts the ignition will dump raw fuel into the exhaust and could cause this. Also, if you are running a straight pipe or even gl*** packs you will hear some popping and noise from the exhaust normally. Mark
