My 1950 M has me puzzled and I am lost ..
It just died one day and thought it was bad gas cause I had just refueled it about 10 mins before . Cleaned carb drained fuel after cleaning gas started pouring gas like float/ needle valve was stuck open after many times of removing and reinstalling with the same outcome found float to be bad and rebuilt carb with kit from NAPA. Now it still wont fire so I put new plugs D21 . I have a spark going to and through the plugs gas to carb and now ??? points condeser button ??

It is a Marbel shriber carb with 3 adjustment screws. THanks

You say you have spark but is it a nice blue/white and will it jump a 1/4 inch gap or more at all 4 plug wires??? What happens if you spray some starting fluid into the carb??

Check your compression. You may have a broken intake valve spring.

ford grain truck done the same thing last year,run perfect until I shut it of and tried to restart it 5 minutes latter, had fuel and had spark at #1 plug it looked a little weak tried to pull start it would hit a lick,of course it was in line at the grain market,son brought the pickup to me it happened to have a spare coil in the box temporarily hooked it up it fired right up

Maybe the ignition switch shorted out. Check all the wires going to the switch.

No offense Gene but if he's got spark it's not a shorted out ignition wire.

Gas to carb, but.... How about gas to the cylinders?

If you pull a plug after cranking are the plugs wet?

You could have stopped the leak by preventing the needle from opening and letting any gas into the carb at all.

Just a thought. Have a SC case that did the same thing. Checked everything out a number of times. Tried everything. Last thing I did was put new plugs in and it fired right up and ran perfect. The old plugs would just not fire under compression anymore and that happened instantly. The old plugs were NGK. Was a real head scratcher for a while. Good luck. Allan.

Found it last night ... The smallest thing in the world... the nut that holds the points and condensor wire on the inside of distributor cap had backed off .. I had a spark but apparently not enough at the plugs. Didn't find it the first time looking under distributor cap .... THANKS for the replys
