34 Pic Carb
009 Dist w/Electronic Ignition


I have seen cheap distributers and electronic ignition modules do some weird things. You really should have a back up points/condenser set anyway. If not ,get a set and take out the EI and give it a shot. Cheap and easy process of elimination . The SVDA distributor is known to work better with that carb as well.

Let's stay with this here and see if we can figure this out. . We are going to need to know some things like what year of engine it is at least the PICT 34/3 to match a distributor but for example if your Ghia is a 1971 and you likely have the Original Carb then you could look at this web-site and find the distributor it uses: http://www.oldvolkshome.com/ignition.htm
For example a 1971 Beetle used the VW 113-905-205AJ, and the 72 and 73 were VW 113-905-205AN, 1974 VW 043-905-205C, Looks like the AN can be used with any year. The Ghia may have used something different! Someone will know so keep the thread going and let us know what you come of with. Many carbs would work but nothing as well as dual IDF Webers or DRLA Dellortos. Also consider getting a Dial Indicator if you don't have one and profile the cam.

Not sure what year the engine is, my engine builder who has now blown me off since he can't figure out the issue or knows and doesn't want to deal with it. He built the engine w whatever case he had but I will see if I can find an engine number so to find out the year.
My ghia is a 70, I've tried 4 carbs, three 34 pic 3 carBS and one I think 31 pic which was a Solix. My current carb is a brand new EMPI 34 pic 3 that was tested on another engine prior to the install on my engine. And with every carb I have had the same non idling issue:(
I'll look into the Amazon item you suggested, Ive spent so much time and $$ I can't afford to replace the engibe again so thank you for your help Smile

So the only distributor you have is a 009? With pointless module? It's going to have to be set to 7.5' static. You could try blocking the hole in the throttle plate with it. That may work. Not sure blocking the hole may be a way to make it work with the new SVDA distributors. http://vwparts.aircooled.net/Pertronix-Brand-SVDA-Distributor-12-Volt-Version-p/d186504.htm

Maybe put up a video of it running and trying to idle?

Actually as I think about it you should be able to identify your cam without the dial indicator Just by looking for when one of the valves starts to move open or closes. Does the engine have a degree pulley?
Stock 1600 cam specs. vs
W-100 For example #1 Intake valve with the W-100 are going to be moving open at 14' BTDC but on a Stock Cam more like 0' to 7.5' BTDC "I think these numbers are @ 50 Thousandths with valves set to .004 clearance." The problem with this being, how to tell where 50 thousandths movement is. In reality I see #1 intake start moving Open @ 33' BTDC #3, W-100 Cam.

Sorry bud, that's just what the mechanic at the shot told me. Said the timing is supposed to be around and 8-9 but had to up it to 29-30 to get it to idle

Hope this helps...

Going to my buddies house Wednesday night, he's built a few of these engines and I'll see if he can figure out the cam size.

I was out again getting ready to tinker w/this again when I noticed two things.

1. A hair line crack under the fuel pump, would this cause any issues?

2. There's a very small leak under the gas tank. It's not dripping but was just wet. This can not be the issue, I've already tried an external gas tank with the same unsuccessful results.

For some extreamly odd reason it idled this time and for the first time and I couldn't get it to dye. The mechanic at my local shop said in order to get it to idle, he had to set the timing from an 8 to a 29 or 30 so not sure if he left it at the higher number or not but will ask him tomorrow.

Sounds like you may have a fire hazard with that small gas tank leak! I would investigate. Could just need new fuel lines! This is really really important! There is gas tank epoxy you can use on the tank if you can find the leak.

Your case is cracked there, someone screwed the fuel pump stud into the case too far. Remove the fuel pump and double nut the stud and set it back with "JB-Weld" backed out an 1/8" or so from where it is now. It should not be a problem but next time the case get's rebuilt it could be welded.
"he had to set the timing from an 8 to a 29 or 30" Yes that is correct for a 009 distributor.

Just got back from my buddies house after beating on my ghia for about 2 hours:)-
After about 1.5 hours, we were able to get the engine to idle but couldn't get the timing below 20 degrees.
We took a hard look at the pulley and noticed the pulley has seen it's day so my friend had a numbered pulley we put on. And not timing at idle is 12 degrees and idles. When we run the engine at high rpms, the timing advances to 34 degrees.

From what everyone says, timing should be around 7 degrees at idle?

Also, he did not have the tools to measure the cam so that is still on the honey do list:)

What's everyone's thoughts on my timing being at 12 degrees during idle? because if I drop the timing lower, she wont idle anymore.

Thanks again!
Lee

Do you know how high it's idling? Rpm wise should be 800-900 rpm. If it's higher than that the distributor is already advancing. I'm unfamiliar with the 009 but if it has spring and weights for the advance plate check to make sure they are not worn out. Or doesn't have too much/too little weight.

l still think you should try putting in a point/condenser set. points/dwell affect the timing. That is why you set dwell first before timing. You just want to trust your cheap electronic ignition ? The main concern about timing is the full advance @3000 rpm. 28-32` is average . But you need a strobe gun to set it. Static setting the timing to 12` could put your full advance over the limit and cook your engine.

Before putting the new pully on we did try a new distributer (009:( with points w the same results.
Yesterday we used a timing light to set the timing and I am concerned about it running hot so maybe I need to put a temp guage to monitor it?

34 degrees max advance and 12 idle is too high in my opinion, regardless of what dizzy you are running..This is also going to make the car run hot and burn the pistons..28-32 is where you should be, and even 10 degrees BTDC is the max I'd ever run a motor..

Have you spoken to the engine builder ? I would at the very least take to a VW air cooled repair shop before tearing down the motor. Some times a second or third pair of eyes ...

Engine builder has ignored me and blown me off since he can't figure it out. And i took it to the local shop where they specialize in these engines. The mechanic at the shop who has been working on these engines for 30+ years says it has to be something w the cam, tooth off or bad grounded cam.

My other thought was to put a temp guage on it and see what the temp numbers are before pulling the engine.
