35buickakaBelle Posted June 1, 2020 Share Posted June 1, 2020 (edited) What could be wrong? it cranks but won't start. I put fuel in the carburetor and still no start. I think no spark but how do check that. Or any suggestions why it wouldn't start would be greatly appreciated. still 6Volts system . Thanks Luis Edited June 3, 2020 by 35buickakaBelle (see edit history) Link to comment Share on other sites More sharing options...
Pete Phillips Posted June 1, 2020 Share Posted June 1, 2020 Pull one of the plug wires off of a spark plug, but hold it about 1/4 inch away from the plug while someone cranks the engine. If you don't see any spark jump across the gap occasionally, then you have no spark. Get a test light and see if you have power at both terminals on the ignition coil. Clean your points. Has the car been sitting long? You don't give much information to go on. Link to comment Share on other sites More sharing options...
edinmass Posted June 1, 2020 Share Posted June 1, 2020 Putting fuel down a carburetor is EXTREMELY dangerous.............if you don't know how to check spark, you don't have enough skills to try and work on the car. A backfire can blow the gas thats dumped down backwards causing a large fire event that can burn you, the car, and the garage. Don't try and service the car without someone knowledgeable about pre war cars. It just isn't worth it. 2 Link to comment Share on other sites More sharing options...

Has the car been sitting long? You don't give much information to go on. car was sitting for about 7month. I was driving around end of last year and it stalled on me and then it would start after that. So i put it away for the winter and i decided to start working on it to get it running. I diid a full tune on 2018 new wires, coil, spark plugs, gastkets, water pump, radiator etc... I did try the spark test but i didn't see a spark going to do it again and also and check the coil. thanks Link to comment Share on other sites More sharing options...
Marty Roth Posted June 1, 2020 Share Posted June 1, 2020 First check for spark at the ignition points: 1. remove the distributor cap 1A. use a piece of cardboard, matchbook cover, or a points file to clean both surfaces of the points 1B. if you see a cone shaped buildup, file or replace the points 2. rotate engine so that points are closed (making contact between the two parts 3. with a Non-conducting item, such as a plastic or wooden object, and ignition "ON", separate the points contacts 4. you should see a little spark at that surface 5. if no spark, look to see if there is a bare wire which may be shorting out leading to, or inside the distributor Good Luck, and please let us know your progress 2 Link to comment Share on other sites More sharing options...

Don't try and service the car without someone knowledgeable about pre war cars. It just isn't worth it. Push the car outside and go through the typical diagnosis. If a car has compression it needs air/fuel/spark to run. I am not in favor of taking stupid risks but if nobody took a chance to learn something there would be no hobby and no amateur mechanics. A little carb fire never killed anyone. Leaving the 5 gallon pail sitting next to it probably burnt down a garage or two. Link to comment Share on other sites More sharing options...

carbking Posted June 2, 2020 Share Posted June 2, 2020 Test! As mentioned by others in the thread: you need (1) compression, (2) spark, (3) air/fuel mixture, (4) all arriving at the right time. Compression testers are inexpensive, and easy to use. If the compression is bad, fixing the spark and/or the air fuel mixture won't matter. Test compression first. Spark testers are inexpensive, and easy to use. If the spark is bad, fixing the air/fuel mixture won't matter. Test the spark second. If the spark is good, check the timing of the spark. If compression, spark, and timing are good, fill the carburetor through the bowl vent rather than pouring gas down the throat of the carburetor. See if the engine will fire. If it will, great. If not, maybe time to enlist some more experienced help. And a fire estinguisher rated for gasoline sitting within easy reach is never a bad idea when trying to start an unknown engine. Have fun, but be safe. Jon. 1 Link to comment Share on other sites More sharing options...

A fellow AACA and HCCA member almost lost his life on a hot day when the gasoline fumes surrounding the engine caught fire from a backfire on his father's brass car. And it is the rest of the oil covered engine and hood insulation, on later vehicles, that gets out of hand quickly. No longer a little fire. Fire extinguisher at a minimum, and NEVER lean over the carburetor while someone cranks the engine. It takes a while to grow back the eyebrows and other hair. Seen that. Don't want to see it again. 2 Link to comment Share on other sites More sharing options...
