The basics need to be checked. Both the fuel delivery to the carburetor and the ignition system should be looked at. Fuel supply to the carburetor including a volume measurement needs to be checked. In the ignition system, spark at...
This problem arises with older trucks. The harness, unless it is damaged, is not usually the problem. The problem usually is in the pins coming loose or making bad contact in the fuse box. When this happens, you start loosing...
Since this is a 1970 model, then you may have a problem with the ignition system or the carburetor not getting or giving fuel. The points in the distributor or the carburetor may be plugged. I recommend having a mechanic,...
You likely need to bleed the pressure out of the hydraulic system. Improper installation could also have caused the problems. I would have a certified mechanic, such as one from YourMechanic, inspect your clutch issue and make the needed repairs...
Hello. If the wheel will not move, then the brake shoes are stuck to the drum. If the vehicle has not moved in some time and if the parking brake was not being used, then the shoes typically corrode to...
The first thing to do is to look at and check the points and then check the fuel pressure to the carburetor. If all is okay, then check the carburetor for flow of fuel into it by using small spray...
Low fuel pressure caused by a dirty filter may offer enough fuel for a start but not enough volume to support idle. Have an experienced automotive technician, such as one from YourMechanic, diagnose why your car is starting and stalling...
Hi there, This is a very difficult question to answer without being able to actually look at everything in person. There are a lot of variables here, especially since somebody else took this all apart over the course of two...
Hello. If the engine will crank over and it will not start after it has run for a while then most of the time this is caused by a failing carburetor. Most of the time it will flood out and...
Hi there. Check the transmission fluid and make sure that it's full. If the fluid is good, then either the shifter cable could be stretched or the main valve on the transmission may have came off the shifter inside the...
While we at Your Mechanic do not perform engine replacement or swaps, I can tell you some basics. Considering you are looking to install a 2004 Ford engine in a 1970 Chrysler product, there will be an extensive amount of...
Hi there. Check to see if the fuel that was in the system was old and sitting for a while. If so, I recommend putting in a fuel water evaporator chemical that can be purchased at a local parts store....
Hello - this sluggish starting behavior sounds like inadequate current reaching the starter motor (or a worn out starter motor). Start by checking starter circuit electrical connections - make sure they are clean, with no corrosion, and there are proper...
Hello there. Many common faults will cause your 1970 Chevrolet 350 engine to bog down. The most common faults are engine running to rich, improperly adjusted throttle linkage, fuel pressure to high, or a vacuum leak. A qualified technician, such...
Hello. Thank you for writing in. Do not assume right away that you have blown a head gasket. When the cooling system overheats and throws coolant all over the engine bay, every hot part of that engine will create steam....
Hi there - the good news with classic cars like yours, is that the electrical systems are pretty simple for diagnostic purposes. I note that you didn't list a new ignition switch as one of the replaced components. A failing...
Hi there. The most common cause of the problem you are having is when engine oil blows up in one of the engine cylinders. What may be happening is that the engine cylinder pistons aren’t sealing properly due to wear...
Hi there - yes, this is a very large engine, in a moderately-sized place, with lots of heat transfer issues! As you suggest, heat shields, or wrapping the exhaust manifold (headers?) with "heat wrap" to keep the heat inside the...
Hi there. Although the electrical systems on older vehicles tend to be much simpler in design, in many cases, issues like you've described can be very tricky to trace. It could possibly be something as simple as an expose wire...
Check the battery cables and make sure that they are tight. Then check for power to the starter. If there is power to the starter, then check the power to the starter solenoid as the ignition switch is turned to...
