    It is a 1961 Plymouth Valiant V-200.


    Down  here it was simply known as a Valiant, our first ever Chrysler Valiant whats more.

  2. Well it would appear that float needle isn't doing the job of stopping fuel flow when the carb bowl fills up.


    So what's causing pressure build up when the engine has stopped, a number of possibilities exist:

    • do you have an electric fuel pump still running? 
    • Is there enough heat to cause fuel boiling?
    • some  carbs have an anti percolation system inbuilt to prevent residual heat causing too much carb bowl build up after shut down
    • Is it possible that the fuel cap vent is blocked, causing excessive tank pressures after shutdown?  

    Putting aside the other problems you have encountered it surely won't run right until you get this sorted.

    Thanks hcris .... I have exhausted all avenues here in Australia, and was hoping to locate some in the US { or anywhere else for that matter } ... Bottom line is my drums are in desperate need of replacement as I want to drive it to South Australia in September ...  a round trip of 2000 kms.  or more over a period of 10 days ...

    and I would feel much more comfortable  { and safe } knowing that the brakes are the best I can possibly get .. I have even contemplated a disc brake conversion , but that opens a real can of worms regarding engineering requirements for the conversion


    I have an idea that 34 Plymouth were the same size, perhaps another avenue ?

  4. Reckon you will struggle with this,  there are some people who spray metal inside the drum and remachine to get the lining surface back. As to replacements, I have never heard of anyone downunder, swap meets etc are probably your best shot. Have a look in Restored Cars for drum refubishers.

    Hey guys so about a month ago I replaced the head gasket on my 1949 Chrysler windsor, yesterday as i tried to start it there was antifreeze shooting up thru the carb, so i took the carb off and there was antifreeze in the headers, there was no water in the oil or anything and looked ok. Not sure as to why there is antifreeze in the headers tho. Any suggestions? 



    Take the manifold off again and put sealant on the retaining bolts, some of them go into the water jacket.

    That might not be 100% accurate, I can't really see enough of the car to tell. I know I have seen side trim like that on a USA (Plymouth) model, but the only pics I can find like that are 1962 Australian Chrysler Valiants. Any Valiant made from 1960-1962 would have had that roofline.


    Edit: It's a 1961 Plymouth Valiant V-200 if it is the USA model. If it's Aussie or built somewhere else, all bets are off...






    Have a look at some of the Australian Chrysler websites: built by Chrysler down here, they sold very well. 


    Unlike the US product where this body style was marketed for both Plymouth and Dodge variants, downunder they were only sold as Chrysler Valiant.

  7. Think I would be looking at the light switch, brake / tail and headlights are usually wired independently, very unusual to have headlights fused; more likely to be a resetable  breaker in the headlamp switch; unless of course we are talking prewar.

  8. OK , well how about knocking the timing back a few degrees to set say 16" vacuum as suggested by Beemon, then see how it runs.


    Another factor could be the carb float setting too high, this will make it run a little richer and at idle you may not get enough adjustment out of the mixture screws.


    But its important that you try these things one at a time to see what effect they have.

  9. Perhaps it might be easier if you were to tell us what make of car it is,  someone may then respond with a wiring diagram.


    The answer to your first question is yes, some coils have a built-in ballast reistor, some have an  external resistor.

    I need to remove my steering box and shaft. I need to rebuild it. 


    I am thinking I need to take off the shaft 1st. the top of the gear box looks like the shaft has a LARGE nut that will require a 16" crescent wrench to unscrew then the shaft will pull out. IS THIS CORRECT? 


    2nd, I will remove 4 bolts from the frame and the steering gear box will come off of the frame. 


    can someone tell me if this is the correct steps to remove driving shaft and gear box OR DOES IT COME OUT AS 1 WHOLE UNIT?



    First you need to disconnect the drop arm from the tie rod, then the 4 bolts that hold the steering box to the chassis. I find then its easiest to remove the steering wheel and drag the whole lot up through the floor (having of course removed the floor boards/panels). Maybe remove the steering wheel first rather than later, oh and there will be wires running down the inside of the steering column that need to be disconnected.

    With that being said it ONLY gives you a basis & you fine tune, advance or retard, as nec. to get the performance, mileage or pinging to where you feel most comfortable.




    I thought the bushings I sent mostly solved your problem???



    The whole point of using the vac guage is to fine tune,  get the basic settings with the timing light then use the vac guage to adjust timing and mixtures to obtain the highest vac reading, then back timing off to lower your highest vac reading an inch or two. Follow up with a road test and listen for pinging, if you encounter pinging back off timing in small increments until it stops.

    So I wanted to tune my carb and adjust timing using a vacuum gauge. I saw a few videos of people doing this on old Corvettes and mustang's so I thought I would try it since I have a vacuum gauge. 


    I read though that I need to use manifold vacuum,  and that the 63 with stock carburetor only has ported vacuum. Is there a way to do this on a 63 or is the ported vacuum too unreliable? If I did this which vacuum source would I use? (Advance port, port behind carb to PVC, port on the manifold that leads to brake booster,ect.)


    To note I have always just tuned it to the smoothest idle using a tachometer and using the specs in the book, but using a vacuum gauge has intrigued me.  


    You need to use a vac source direct from the manifold, taking a vac line off the carb wont do it for you as the vac source is usually plumbed in above the throttle plate.


    Alternative sources like the brake booster port or PCV manifold connector are fine ie any port that taps straight into the inlet manifold can be used.(make sure you have an airtight connection)


    The benefit of vac tuning is that you get to see when the engine is running at best, as opposed to manufacturers figures, which are a good starting point but dont make allowances for todays fuels, engine wear etc. all of which can affect engine performance.


    And as Rivman says, when you get to the highest vac reading back off an inch or so of manifold pressure before locking everything in place, this avoids potential pinging.

  13. Whilst I wouldnt question your reasoning on the necessity of a vac amplifier, in the real world a long hill or even a strong headwind at large throttle openings, is a not uncommon reason for a vac tank not being able to keep up with engine demands. Most of us would probably never encounter this problem as the majority of our motoring is at city speeds on the straight and level; commercial vehicles were a different matter with loads and distances significantly greater often requiring the fitment of a booster.

    I always thought the step bore cylinder was an attempt to even up braking effort on front and rear shoe. The trailing shoe does much less work on our fixed anchor simplex system. This is from Wikipedia:

    image.png.65ca34b7de723115d71854a79f1ebddd.pngBy putting a larger cylinder on the trailing shoe, the effort  from the shoes can be evened up a little. A 1-1/4 to 1-3/8" diameter increase makes a 21% increase in the force applied to the rear shoe. This is hardly "not much effect" as people have been advised.


    Correct, I was over simpliying things in an attempt to highlight that the cylinders were step bored, there is in fact a whole lot more to the science of this feature but I didnt think it was relevant to the topic. 

    Mea Culpa.
