I have a hillman hunter that doesn't run very well... She blows a lot of black smoke and idles similar to a rotary... If i put my foot on the gas she cuts out... I've had confirmation it's not a blown head gasket but don't know what it could be... Any ideas? Help!

Hi
Was this confirmation given after a compression test? Because thats what I would be doing right now for starters.
Next ensure that the points are in good order and set correctly at about 15 to 16 thou. You should then switch on the ignition and open the points up with a screw driver a few times. You should only see one good spark when you do this, the rest of the time there should be no spark. If it sparks strongly each time then the condenser is shot.
If a compression test checks out okay, and the points are in good working order, then it could be that the diaphragm in the accelerator pump has split or come away.
Remove the air filter and open the choke so you can see down into the carb, turn the throttle lever to full throttle by hand quite quickly a few times, and see if you can see a squirt of fuel being thrown in. If not then it is very highly likely that it is the accelerator pump at fault.
Your next check would be the fuel level in the carb. There should only be about 2 centimeters of fuel in the bowl. If there is more then check the needle valve as it could be sticking open and ensure that the float level is set correctly.
Buy yourself a COLOURTUNE from your local Autofactors. It has a glass window which allows you to see into the combustion chambers whilst the engine is running. The idea is to adjust the fuelling until you get a nice blue flash from the chamber. This tells you that you have got the fuelling spot on, and you can also see which chamber isn't combusting properly.
Cheers

Sounds very much like your choke isnt releasing , or the carbaretor is flooding, remove air filter pan look inside the carb , you will see a round flap does it move to open position when the choke is operated , if not thats the problem ,if it is a auto choke it should open slowly as the engine heats up ,if it does then it must be somthing else , watch for petrol running out the top of the carb when engine running, that would be carb control valve stuck and making the engine run very rich , if not there can only be one more thing , screw in the mixture screw on the side of the carb it has a spring on it , screw it in untill it stops then screw back two complete turns, that is the standard control setting which should be about right

OK a bit ageing but I'll give it a shot
Your running problem could be a number of things. Firstly I would check the contact breaker gap it should be 15 to 16 thou ensure that there is no "tit" on the points and no I am not swearing
Next point ot look at if that is OK would be the carb. They had a small accelerator pump fitted that would give a little squirt of fuel each time you pressed on the gas pedal. If this function fails it could be causing your problem.
Now lastly if all else fails I would go to a local independant garage and look for the oldest guy in the place like "Bernie" from Heartbeat and ask him. Hopefully he will remember these with affection and be able to help you
These 1725 engines were reasonably robust and you should be able to get it running well with a little TLC. Even if it is worn a bit. Unless completely clapped out it should run kinda OK
Good luck with it.

Hi there, From what you have said, it seems your old car is trying to run without any fresh air and kicking out black smoke which is over richend mixture, make sure the air filter is clean, spark plugs are clean and gapped properly, check all adjustments are ok ie tappets and points and rotor arm is ok, check choke mechanism engages and disengages when the cable is operated or when the wax stat works when the engine is started and warmed up. make sure the petrol is fresh and a good battery fitted, start car and warm up properly disengaging choke when not req'd. Also check carb seals and lifters/slides
Good Luck
ps check timing too static, idle and mechanical.

What year is the car? Anyway, if it has a carburetor then you might want to get it rebuilt and if you dont know the air-fuel ratio? Then take it to a shop and ask them to do it for you. You can do it yourself but, you need the repair manual for that. Also you need a fuel-air ratio gage for that. Those are difficult to find now in days.

try the rubber diaphragm in the carb it will have a small split on it by the sound of it these were good engines 1725 cc was the best with twin carbs or the very best was a holby engine

the diaphram in the carburetor may have a split in it or could be a float problem. either way it is a fault with the carburetor, shouldnt be too dear to get fixed
