Timing

[BeagleRock]

Hey gang I just installed a Chinese dizzy and new carburetor "2150" to replace a 7200VV carb and dizzy. Here's the question, it had a crank shaft sensor instead of a pointer like on normal engines. Upon setting the timing to the best of my limited ability with some assistance from a neighbor holding his finger on #1 plug hole to find or get close to TDC it would spit through the carb about every other revolution imo. Since I'm sure I'm not 180 out on the timing and can't get it to start. I stand at the mercy of the brilliant minds here to take a moment to put yourself in my position. What would you do? Thanks in advance Beaglerock

Put a small piece of toilet paper in the hole and turn the engine over with a ratchet. When it shoots out, you are close to TDC. Look at the keyway on the damper/crankshaft. It should be straight up when TDC. Move the engine slightly, either way, to get the keyway at 12:00. You know have TDC.

Are you referring to that deep notch Pete?

Make sure your neighbor "mechanic" knows two things about a Ford, #1 cylinder is front passenger side and cyls. are numbered 1-4 on passenger side and 5-8 on driver side, also firing order is 15486372 on 302 and 13726548 on 351.

Exactly 👌

Yes the deep notch.

The crankshaft sensor went to the computer, which you've now neutered.  If I remember correctly you have to change the timing cover to get a proper pointer.  But, I've seen ghetto pointers made by capturing a piece of wire under a bolt and bending it to point at 0 when at T

"New" 2150?

Yep computer gone ,smog pump and lots of vacuum hoses. Which BTW a certain 2150 carb has a port on the power valve and I haven't a clue where it should go. Any idea 💡

There's this website that I found that has a lot of info on these trucks.  And the page at Fuel Systems/Carburetors/Motorcraft 2150 has a tab called Internal Systems.  And if you scroll all the way to the bottom of that you'll see a picture that says "The carb on the bottom has a power valve cover with an external fitting for connection to a manifold vacuum port."

Okie dokie thanks Gary!

And without that hooked up to manifold vacuum the power valve is going to be wide open at all times.  So the mixture will be RICH.  And it may cough and spit like it has a timing issue.

Thank You I will plumb that on the next decent day that I'm off. Supposed to get cold again 🙁

Hey Pete that notch in on the crankshaft is at 3:00 when my finger gets blown out of cylinder #1 and winds up around 4:00   ironically the old mark PO put on there is approximately an inch & 1/2 past the old disabled crankshaft position sensor. There also appears to be an old rusty  pointer there that is a part of the mounting assy. That the CPS is mounted to 🤔

Water pump to the top hose runs right across it is why it's difficult to see.
