 |

I have installed a big bore kit on my 1965 6 volt beetle so from 1200 to 1385. I have a 30PICT-1 carb and a distributor with the vacuum advance. I have been setting my timing at TDC. Should I be advancing to 7.5?

What is the part number on the distributor?

Most likely, yes.
What distributor model do you have?
I had a big-cap 40hp unit, that same carb, and I timed it at about 7.5 degrees BTDC.
Your distributor looks different. Does it also have mechanical as well, or is it vacuum-only?
The change from 1200 to 1385 should not change your timing, unless you changed the CR, which can go up a bit if you just fit the larger volume PC set. If they set your CR back to normal by shimming or machining the heads then you are fine with the stock unit. |

not sure I think it is 009, I will have to loosen up so I can read part number, I will post when I do.

It's vacuum only either a 205K or 205L.

I recently purchased this distributor but have not installed since the original is working fine, if I do install in place of the Bosch 009 distributor what should timing be set at?

It will not work correctly with that carb, the vacuum signal from the carb will not produce enough for the vacuum canister.

is there a modification I can make to the carb for the electronic ignition Glenn? I bought the card from Volkblitz hate to change it runs great.

Wish you luck with that aftermarket distributor. Mine failed in less than 2 years. |

Why add another failure point that will leave you by the side of the road (ignition module)? Spare points are cheap and reliable!
Few (if any) aftermarket ignition setups are of the quality VW//Bosch put into the original parts. For a 1385 you need nothing more than the stock distributor.
Sell that unit and put your money elsewhere will it will make a difference.
The larger carb is a nice adjustment for the displacement increase, and is also reliable.

The distributor you have installed there is a 111 series that is correctly matched to a 28 PICT carburetor not your 30 PICT 1. The vacuum signal from the carburetor is a mismatch.
That distributor delivers @ 20 degrees of advance from @ 50mm Hg, and is typically static timed at 10 degrees before TDC. The distributors that matches that carburetor deliver @ 25 degrees of advance from @ 65 mm/Hg of vacuum.
Bottom line; it'll run but not at it's best. It will fully advance sooner than designed.

A "205 K" could be any of three other distributors. This one has the small saucer shaped vacuum canister so it is a 111 series, Either a ZV/JU 4 R 3 ( a 111 905 205 L but that number has never been stamped on a distributor to my experience), or a 111 905 205 M or N. These are all timed at 10 degrees BTDC when static.
a "205 L" could also be any of three other Bosch distributors and even a Garbe Lahmeyer distributor if it's a 113 905 205 L.

TASB what distributor do you recommend? I have a buddy who is willing to buy the new Flamethrower from me. It is a Bosch OEM distributor original part. Not sure of the part number I will find out what number I have in the morning and repost

when I bought the car it had a Frankenstein carb on it half 28 and the other half 30. So I had Volkzblitz build the 30pict-1 for me. My bug is still 6 volt. I also put in a Big Bore kit from AAP so I believe it is 1385 cc. I gave Volkzblitz that info when he built the carb

The factory match for a 30 PICT 1 Solex carburetor is a Bosch 0 231 137 009 VW # 113 905 205 K. It is a vacuum advance only distributor that delivers about 25 degrees of advance and is static timed at around 7 degrees An SVDA distributor like the Flamethrower would not be a good choice. It looks like the flamethrower has a points replacement module in it so it wouldn't have worked in any case. With points and condenser the voltage is irrelevant.

found this one:
https://www.thesamba.com/vw/classifieds/detail.php?id=2263755
found a lot of others online but this is only "K" I could find. Should I get it with new vacuum canister?
Or if you know of another source.
Thanks for your help.

The 205K is as basic as you can get so it's pretty hard to mess it up.
Price is good, but not sure why you would need 10 condensers.

Over the years I have come across many vacuum advance only distributors with issues which may not be caught or solved by the home mechanic:
incorrect/leaking vacuum canister installed
broken ground cable
broken cap clip with worn un-repairable bosses
missing broken shims
drive dog installed in reverse
stripped threads on points hold down screw
wrong points plate installed
wrong advance return spring installed
overtightened/bent clamp
just to name a few. Not as simple as some might try to make it seem.
