John; when I do cold start the engine in the winter I usually use a bottle of gas mixed with 2 cycle oil. I pour that mixture down the bowl vent and the throat of the carb. Paul

John; I'm trying to do what Mike of Mike's carburetor recommended. He said leaving a car not started for over 6 months would lead to clogging of the small passages in the carburetor. So I try to start the car every once in a while over the winter to get the gas and other fluids moving. Paul

To all respondents; thanks, with the help of the board I (and my neighbor ) I replaced the timing chain about a year ago. Starting improved dramatically. Car almost jumps to start once I turn the key. I can't understand why some board members don't believe its carbon buildup on the valve thats...

I think I have a sticky intake valve(s) on my 50 year old 440 engine. Coughs up combustion gasses through the carburetor on initial startup (haven't done a compression test). I suspect carbon build up on the valve. Watching YouTube I've seen testing on a number of products (Marvel Mystery Oil...

Thanks for reply but I was thinking more about initial startup. Paul

Looking for battery for my New Yorker (440 engine, MSD coil). Fellow from MSD said the MSD coil needs a strong signal to produce a quality spark at the plug. I'm thinking of a 850 CCA Interstate. Stopped at Advanced Auto and they showed me an AGM battery. Saw where AGM batteries can produce 900...

battery on my 440 New Yorker is 3- 4 years old. Tested by Autozone and Interstate is was found to be "good" with a little over 600 CCA. The battery should have 800 CCA. I'm wondering if the lowered CCA would cause reduced current (amps to the coil) and therefore make the car harder to start...

Does anyone know the pressure of the fluid in a transmission line cooler hose under operating conditions (in psi)? Reason is I'm trying to patch a transmission line in my 1975 New Yorker with 727 transmission. I'm debating on whether to use a cooler hose with 2 clamps on each end or a steel...

Still don't have an answer about transmission fluids. Can I a Ford/Mercury transmission fluid in a Chrysler product . Or does the New Yorker require a specific Chrysler transmission fluid? Paul

After driving my 1975 New Yorker I saw a small pool of transmission fluid on driveway. I think one of the lines has developed a leak. My mechanic wants $300 to replace the lines (over the phone estimate). I was thinking of cutting the original steel lines close to fittings and splicing in a...

Watched the movie "The Sting" with Newman and Redford for the upteenth time. Does anyone know the make of car the gangster Doyle Lonnegan was chauffeured around in? It was a long black limousine with suicide doors. I'm thinking Chrysler Imperial or Packard but I'm not sure. Either was it was a...

I've been using Shell Rotella diesel oil for my 75 New Yorker cause it has ZDDP for flat tappet engines. Read an ad for Valvoline VR1 oil. They said the diesel oil has the wrong ZDDP for flat tappets and the Valvoline VRI has the right ZDDP. I don't understand the difference in ZDDP. Has anyone...

What is OOTB? Paul

Watching Simon Fordman working on a Torino on You Tube. The guy is brilliant (no words spoken, no emotional outbursts when things go wrong; just a steady, methodical step by step process). So he takes the gas tank out and puts nuts and bolts and chains in the tank. Then he welds a bar to the...

Plan B is to sell my New Yorker and buy an EV. I read where they have electric motors now that can spin at 30,000 RPM with 98% efficiency. No more carburetors. Paul

I recently posted about a clogged idle circuit in my Holley 4175 carb and I posed the same question to Mike of Mike's Carburetor. I told him I hadn't started the car an about seven months while I worked on the timing chain. He wrote back that 7 months was too long and the gas had probably turned...

4; this brake cleaner is flammable. The only reason I use brake cleaner (for cleaning carbs and to start my lawn mower) is because it's cheaper. Paul

1975 New Yorker with 440 engine and Holley 4175 spread bore carb. Replaced timing chain and engine starts and runs smooth until engine comes off choke. Then the idle is not so smooth. Tried adjusting choke but that doesn't seem to be the problem. Now I'm thinking that because I did not run the...

CBO; "leaner" - meaning I rotate the plastic cap clockwise? Paul

Have a Holley 4175 spread bore with electric choke on a 440 motor. Changed the timing chain and the car starts right up and runs smooth for a minute or two (even with a load on) and then it starts to falter and the idle with a load on becomes rough. I'm suspecting the choke needs adjustment...
