Engine wont fire
OK, got the weber put on today and tried to fire the motor and it wont start...it cranks over and everything just wont start up...the carb is definately getting enough fuel, and i believe there is spark because it backfired many times...i put that compufire system on it and had to rotate the dizzy 180 degrees...
does anyone have a clue of what i should look at next??? |

I would go back and check the timing. Firing order. Did the Engine run before you did all this?

I'm not sure what RallyBob said in another post/thread but with the timing marks lined up the rotor should be pointing at #1 or #4, not #3. Maybe that could be your problem

I would go back to the basic's. Set the Engine to #1 (so # 1 is firing) Trace the firing order down, so the the trigger is firing. Follow the timing around in the order that Bob mentioned. Step by step. The bottom line here is that your timing is off. And it sound's like the firing order is off too.

what would make the firing order off... i dont know alot about engines but some would it be the position of the crank when installed?

I'm talking about tracing down the real time firing order. When each cylinder should be firing. somehow every cylinder has it's time to fire. Trace each one as when needed. There has to be timing for each cylinder. You need to find out when each one fire's. And trace it to the relevant order.

Okay, a quick rundown to make sure you're connected right.
Coil wire #1 goes to spark plug #1 Col wire #4 goes to spark plug #3 Coil wire #3 goes to spark plug #4 Coil wire #2 goes to spark plug #2 The notch on the distributor (under the cap) is cylinder #1. Cylinder #3 is the next one over in a clockwise rotation. With cylinder #1 in the firing position (not just TDC, since #1 and #4 are both at TDC at the same time), align the rotor's mark with cylinder #3 by rotating the distributor. That's it. Final timing is done with the engine running. |

That seems simple enough. |

ok the plug wires are definitely in the right order, so im off on the dizzy...
this is what i did to the dizzy...i originally had it set that when the marks on the flywheel were lined up the dizzy was at #1 cyl...i then pulled the dizzy and rotated it 180 degrees, bc the vac adv would be hitting the fan when i turned the dizzy to #3... but just a quick question, when looking at the dizzy when it is in the original location and not rotated 180 degrees #1 cyl is in the 4-5 oclock location, right? so then #3 i had thought was located in like the 10-11 oclock position...

There is no timing to a crank installation, it can only go in one way. There is one rod or main per journal and only one way to go. Firing order can only be set or made wrong by the position distributor or sparkplug cables. |

ok im going to have to pull the fuel pump again so i can rotate the dizzy back the 180 so it is like it was originally...the vac adv hits the head when i try to move it to the 2 oclock location...so once its back then ill set it to the 7 oclock location and it "should" run...
