The old waxstat jet might still be on my bench somewhere, I'll give a look . If it is, I'll switch it out tomorrow and see what happens. I did not do anything with the timing.

As you previously said you possibly kinked the jet tube when installing it i would look at that next. If the waxstat jet is still good you could re install that to see if it runs ok just be careful with the O ring although Joe Curto in NY has them in stock separately if you need one.
I am thinking you are not getting enough fuel at this point.
Do you have an inline filter, if so check that and change it if it is restricted.
I am assuming you have not touched the timing at all have you?

I really appreciate all your tips, thank you very much. I tried spraying fluid around the intake and got no change in the idle. Gave a little spray directly into the carburetor and it and got a small increase in the idle. Pulling the choke out a bit increases the idle but still runs rough. Very sluggish throttle response.

Now i know you removed the intake i am guessing you could have an air leak on the intake gasket but by pulling the choke out slightly maybe 1/2" to 3/4" it should run better.
To check for an air leak with the car running you can check for leaks a few ways. With an unlit propane torch you can put it near the gasket if the revs rise you have a leak. With a 2 foot piece of tubing you will hear a hissing sound if a leak is present. With starting fluid sprayed along the gasket the revs will rise.
Don't mess with the broken wire right now you know it runs without it get to the bottom of the carb issue first.

While looking at the plug wires and such, I found a broken wire connection on the ignition coil. I looked through my Hanes manual and it appears to be the tachometer wire, which hasn't worked since I got the car a couple months ago. The wire gets power when the key is turned on but once I connect it back to the coil, it stalls the car immediately. I give up

Yes the piston seems to move freely as I can hear it clunking down when it struggles to run. I filled my tank up about a month ago. While cleaning the carb and changing the jet, I also changed the exhaust/intake gasket. Just got it to start and idle a few times now but it is running rough. I took turns pulling the plug wires to see if they were firing and when i pulled either of the left two wires, it stalled the engine but when i pulled either of the right two wires, the car continued to run rough.

That should be enough to make it run.
1.Does the carb piston drop down with a clunk and move freely?
2.Is the gas really old?
3.Do you have a good spark?
4.Did you make any additional changes when you originally changed the jet?

Tried starting it a few times then took the float lid off. Looks to be about 1/2 full.

When you changed the jet did you make sure the old jet came out with the old o ring attached as they have a tendancy to stay stuck in the float bowl.
After the car has run for a while remove the float lid and see how much fuel is in there it should be 2/3rds to 3/4's full.
Did you possibly kink the jet tube when installing it?
Does it run better on choke?

I installed new gaskets between the carburetor and the intake and they seem to have sealed tight. I put my hand over the intake to seal it and it kills the engine. Should I be looking a the vacuum lines too?I will start from scratch with adjusting the jet and see what happens .

Summerspop As Doug stated the usual starting adjustment is roughly at least two full turns down on the adjusting nut starting with the jet level with the bridge.
You may want to check for air leaks too.

No offense taken. While I am fairly mechanically handy, i know little to nothing about working on a carburetor. There were no directions with the new jet so I only had what the internet had to offer as far as how to instal . Not sure about centering the jet, and don't know if the jet was flush first before adjusting.

Thank you for the reply. Oil is in the dash pot and seems to move freely I adjusted my jet to sit about where yours appears to be. I got it to run but is very rough and wont idle.

Does it start with the choke?Does the Carburator Dashpot have oil in the top? 3-1 or a thin oil is fine . Motor oil is fine 10-30.. Fine tuning can happen with different oils. Make sure the actual Dashpot rises and falls smoothly?
Check the Jet Height.
Attached picture is where my car is set and runs well. notice the jet is down from the bridge of the carb a few MM.
Make sure your jet is starting 'down' also . Give it a bunch...further it is down = more fuel it is giving - IE Richer... More fuel. if your jet is UP too far . the car could JUST need the fuel.
Choke also 'drops' this jet to give a load of fuel in the same way. turn off choke the jet rises / less fuel.

- I did some reading on things to update on my Mini and one of the things was to get rid of the old waxstat jet. I bought the updated conversion jet and installed it. Also gave the carb a good cleaning. I got it all back together but won't start. If I hold the gas pedal down it kind of starts for a few seconds but as soon as i let off the accelerator, the engine dies. I've tried adjusting the nut on the jet to change the fuel mixture but nothing seems to help.
