Flathead wonít start

I have a 1948 Ford f1 flathead. I can not get it to start. I have rebuilt the carb. Rebuilt the distributor and set the points. Replaced the fuel pump and fuel pump pushrod. New spark plugs, new plug wires. It ya strong spark. Gas flowing good. Did a compression test, most cylinders are near 90. Nothing super low. Got it to back fire once or twice. Can anyone give me any suggestions that I am missing?
thanks

I did not, I did all the previous things in my garage. And I couldnít figure it out so I sent it to a shop near me, I would think they checked that, but I will double check with them about that on Monday.

Originally the mechanic said the compression was low in the 30ís. He said he soaked the pistons in mmo and now there around 90, Iíll double check the timing with him

In the meantime, tell us about the truck. Did it sit a long time? How old is the gasoline in it? You should have at least some sort of fire if it's anywhere close. When I first started my truck (after it sat for literally 20 plus years), I drained about 6 gallons of varnish that used to be gasoline before anything else.

Some guy was auctioning off his collection of 40 cars. And all of them ran the day of the auction besides the f1. I drained the oil and replaced it. And the gas was pretty much empty. So I added about 5 gallons of fresh gas. It has backfired once or twice. But not too promising

The last service sticker is like 25 years old. Not that that means much. But Iíd assume it say for some while. The carb was very gunned up and the old fuel pump was nasty

I agree with Doc, could be the timing is way off. Check to see when cylinder 1 is at TDC on compression stroke, that your rotor is pointing to the #1 plug wire on the distributor. I would also double check to make sure the firing order is correct. (The wires from the distributor are connected to the correct plugs.) Hope this helps!

Sweet thanks, what should the firing order be?

Vanpelt Sales is a great resource for Flathead tune-up information, including firing order.

You can check out the 1948 information here: Flathead Tuneup Specs for 1932-48 V8 (221 & 239)

I bought a beater truck with a flat six that spun over and wohld occasionally back fire but wouldn't start. Checked the distributor and it was rotated 180į. Took it out, turned it around and it fired rught up.

It could be as simple as a bad condenser in the distributor. The cheap ones are known to be unreliable.

Welcome!

So when you rebuilt the distributor, you removed if from the engine, correct? Was the positioning marked and used for reassembly?
