|
hey everyone i have a 70 beetle with a 1600dp, 34pict3, and 034 svda with electronic ignition. i just finished putting motor back on after replacing plugs, adjusting valves, crank pulley, installing electronic ignition, oil, and new carb. the problem now is that is cranks and starts, but i have to have my foot on the gas, and the second i let go it dies immediately dies. it’s also backfiring through the carb and when it does start it’s running rough. i have the carb idle screw turned out 2.5 turns and the mixture screw 5 turns. currently it’s timing is set to 7.5* btdc with static light. firing order is set 1-4-3-2 as shown in the picture. i can choke out the carb when it’s running so i know there aren’t leaks. any ideas?
the top right wire is 1, and the one below is 4. shows in relation to the notch in the distributor where they sit.
electronic ignition, not the notch - just scratched |

i mean i do- but i’ve done all of this work before and never had issues until now. just unsure of what it could be. because it’s backfiring through carb but not lean and the timing should be somewhat set |

Can you take pictures of the whole engine?
Why was the engine removed?
What type of carb did you install?
Can you check for proper spark?
Pretty much go back to homebase and start over.

Compression is?

ill get a photo tomorrow. engine was removed to make it easier for me to pull the crank pulley, valves,plugs, and replaced oil cooler tin. went from a bocar 34pict3 to solex34pict3. i checked sparked and spark was strong and normal. seems like a fuel delivery problem i think since it stays alive with gas at idle, but when i go behind the car it smells rich |

Rotate engine to TDC.
Pull 1,2 valve cover. #2 exhaust valve should be pushed towards the cylinders.
1,2 is on the passenger side. #2 piston is closest to the bumper on the passenger side.
Once you have TDC #1, check the distributor.
Post up pics of valves and distributor.

Was this photo taken with the engine at TDC, or 7.5 BTDC, for cylinder #1?
If taken with engine at TDC, I'd venture to guess your distributor shaft is not seated all the way down into the drive gear inside the hole.

The drive on the distributor shaft is offset to one side, so it can only fit one way, but if the distributor is not fully seated it may be randomly jumping out of the drive gear.
Check to make sure the rotor is fully seated on the distributor shaft, I recall reading somewhere on here about some older electronic ignition modules that had the magnetic trigger ring a bit too tall, and it would not allow the rotor to fully seat, allowing it to slip.
Are you absolutely sure you connected the plug wires correctly? Before you removed the distributor, had you ever noticed where the rotor was pointing with cylinder #1 at TDC on the firing stroke? |

Just throwing that out there...
About 2 months ago I purchased a rebuilt distributor from Bill (Wcfvw69) and a carburetor from Tim at Volkzbitz - pretty much the creme de la creme when it comes to quality rebuilt units.
I installed them and couldn't get the freaking engine to run worth a shit. Just couldn't. I swapped back the old parts and no issues. I reinstalled the new parts and once again I was met with an engine that wouldn't run for crap.
I emailed them both. Took a video and showed it to them. I was questioning everything that was going on because these parts were expensive.
And then, then I found it. Not only once but TWICE, when installing the new distributor (with new cap) I connected the wires as 1-2-4-3. I have NO idea how I did that. NONE! My mind was running on auto pilot and that's how I installed the wires. Once rectified, the engine ran.
Just posting this so that you look over your steps.

Update.. just checked valves and the distrubtor is set right and fully seated. quintuple checked firing order, and it is certainly correct. what other ignition or fuel problems could possibly cause this so randomly?
this is the new ignition i have for my stock bosch 034 - https://www.jbugs.com/product/1847V.html
valve clearance checked and was fine
fuel is pumping through carb powerful and well
have solid spark from coil - all wires plugged in fully
im lost |

| Can you put the points/condenser back in the distributor to verify there isn't a problem with the pertronix? |

Make sure your carb fuel shutoff solenoid is working -- you should hear it click once and it should fully retract the plunger when the ignition is switched on.

distributor was set up correctly. here’s a photo of distrubuter while car is at TDC. rightmost wire goes to 1, under that is 4, above is 3, and top one is 2.
i guess i can replace the electronic ignition with points and condenser to see if it fixes it today |

i only hear the click of the 12v sparking. could this be causing all of the issues? |
