thanks for your help.i will check it out this weekend.is this a common problem with the v12 engines? i'm just thinking of our hot weather in the summer time.

just a update i replaced the the intake manifold that was bad and had the distributer reset by jake fleming and the car is running good but seems to overheat. temp is on the high side of normal. any help ?

i need a intake manifold 3 bolt for a 1938 v12

hello, is there any lincoln zephyr owners in florida

thanks for your reply jim43 i will let you know if i need the part.we think the problem may be the manifold since the vacuum is so low (5-7 hg) or valve problem.

thanks for help i'm talking to jake fleming about having the distributer reset.

yes i read about the vacuum brake in the handbook. i took the vacuum tube off to make sure it was clear and once i put it back the engine is running very bad at idle unlike before.so me and a friend adjusted the timing and it did make a change to the engine this time but it seems like you need more adjustment but thats all the adjustment you have.almost like it is one tooth off. i have had that happen before on other cars. but thats alot more simple on a v8.we also adjusted the vacuum brake ( it was already backed out all the way)but it didn't seem to change anything. i'm in central fla do you know anyone close to me that may be able to help? can i remove the vacuum brake without removing anything else to check the plunger and spring? how do you know where the timing should be? on other cars you have the markings on the engine and use a timing light but i don't see anything.

thanks for your input. in the summer of 08 i had alot of parts replaced since the car had no spark. i had the coils,points,condensers,plugs,plug wires replaced.at that time the engine was tested as well.since then i have checked each plug for spark and all of them are working.also the gas tank has been cleaned and coated on the inside.it just don't seem right to me that timing adjustment doesn't change anything.thats why i was thinking of the vacuum brake. if this is like other cars with vacuum advance. thanks again

hello thanks for your input i found a electrical switch that looks in very bad shape once i get the engine prolem fixed i will look more in to the columbia rear end. i got the fuel pump and carb rebuilt but the car is still doing the same thing runs great but no power on the road. the timing has been adjusted but there is no change in the car. no matter where you set the timing. i was reading in the handbook about the vacuum brake? does anyone think this could be the problem ??

thanks to everyone for the help. i'm having the carb and the fuel pump rebuild and maybe that will help and then i plan to check out the overdrive. i think it maybe in overdrive since it is not to easy to get going from a stop.

hello, thanks for your reply. yes everything is in place and i found the (unmarked) knob i'm not sure if everything works but i plan to try it out soon. is it possible once the car is in overdrive to stop and start in overdrive or do you need to go back to underdrive to get the car going from a stop? can you get up to speed in the underdrive or does the car need to be in overdrive? the car is only getting up to 30-35 mph? i'm just not sure if i other problems or if this all the car can do in underdrive.everything on the engine has been checked out and is ok except for the carb.what is the top speed for this car? thanks again for all your help.
