Hi I am having troubles with my new truck that i just bought. its a 1964 ford f100 with a 292 Y block engine. i bought this for $250. the guy said it ran last week just fine until he was at a stop light and it backfired and quit. it turns over just fine but will not fire i have checked the timing the spark plugs the plug gaps and the spark from the wires and the plugs in the wires everything is fine but still it wont start. so i decided to buy some starting fluid and try that. nothing it truns over and backfires through the carb but no fire it just blows the fluid back out through the top. i have no other clue what i could be. PLEASE HELP ME!! THANKS, Nate
pull the distributor cap off and and watch the rotor when you turn the motor over. See if the rotor is turning. If not, prolly have a busted timing chain. If is turning, bring the motor up on #1 and see if it lines up correctly on the distributor. If it doesn't line up right, the timing chain has jumped. And make sure you actually have fire at the end of the plugs.
yeah i have already done that rotor turns and it is lined up correctly with fire order. and as i already said im getting spark to plugs. thanks for the help keep posting
i had the same prob this week on my 66 with a ho302 and carbed. turns out that the holley got a vacuum leak inside and a new carb fixed it. so it seems that a rebuild kit will do it, and my boat (with a quadra crap)will run like a chanp
One bad backfire can wipe out the stock carburetor. It will not run at all. Ys seem real sensitive in this respect. I recommend a new Holley 2300 2bbl in 350 or 500 cfm you will never look back. It is about the best improvement out of the box you can do to one these early Slicks.
