JBugs - 1971 VW Super Beetle - Timing a 009 Distributor:

Video Overview:

Now that we have swapped out the original carburetor on this 1971 Super Beetle and got it adjusted, we can make sure the timing on the 009, centrifugal advance distributor is set correctly so that the car runs as well as possible. Our tech Sam explains how the distributor advance works and why he isn't a fan of them on street driven cars. Then he goes over the process of correctly setting the distributor timing. Follow along, enjoy and maybe learn something in the process!

0:00 hi I'm Sam with jbugs.com uh now that 0:02 we've got a new carburetor installed 0:04 we're going to go back and double check 0:05 the timing on our double 09 centrifugal 0:08 Advance distributor 0:14 personally not a big fan this 0:17 distributor was originally made by 0:18 Volkswagen as a industrial distributor 0:21 this distributor is either on or it's 0:25 off again not the best thing for driving 0:27 or you want a smooth Advance which is 0:29 what you get out of a vacuum advance or 0:31 a single vacuum dual Advance where it's 0:33 actually running a centrifugal Advance 0:35 like the 009 but it's also running a 0:37 vacuum advance so you get that smooth 0:39 Advanced curve pulled off the vacuum of 0:41 the carburetor Timing prep 0:43 we've got our timing light set up with 0:44 power 0:45 and ground 0:46 and it's cutting getting a signal from 0:48 the number one spark plug 0:50 we're going to go through and 0:54 because we're not running a degree 0:56 pulley we're going to be looking for 0:57 timing marks on this stock style pulley 1:00 and ah 1:03 we got a little fan shroud rub that's 1:04 that high I heard a high-pitched sound 1:06 earlier 1:08 we've got our timing marks 1:11 which are here 1:13 and here and here so this has actually 1:16 got three marks now seeing as I don't 1:19 know anything about this pulley what 1:21 these timing marks are at fortunately my 1:24 timing light actually has an advanced 1:26 feature so I can go through and figure 1:27 out what those marks are but I like 1:29 using a digital advanced timing light 1:32 because I can go through and just set my 1:34 Max advance 1:36 and as long as I know what top dead 1:37 center is I know I'm getting my Max 1:39 advance 1:49 a nice Mark to 1:53 hopefully illustrate this much more 1:56 clearly 1:57 while we're running 2:21 zero time 2:46 foreign 2:58 [Music] Timing info 3:08 so we're getting 25 degrees out of this 3:10 distributor but our initial timing is 3:11 literally set at zero 3:13 so 3:15 on a air-cooled engine with you know 3:19 regardless of which distributor 3:22 uh what fuel or otherwise 3:25 you can typically get away with about 31 3:27 to 33 degrees of full advance 3:30 so 3:31 I just normally will set my timing at 3:34 about 32 degrees 33 31 32 33 fully 3:38 Advanced so what I'll do is actually I'm 3:39 going to loosen this distributor clamp 3:42 rev this thing up I'm going to set my 3:45 timing light Advanced to 32 degrees and 3:48 then I'm going to rotate the distributor 3:49 until that timing mark shows up at 32 3:52 degrees and that will be 3:56 fully Advanced to where this thing 3:57 should perform a lot better at which 4:00 point we're probably going to have to go 4:01 back and readjust the carburetor but I'm 4:03 going to do that right now Timing adjustments 4:07 [Music] 4:38 I'll set the initial timing at seven 4:39 degrees so when the distributor Advance 4:41 is 25 degrees more we should get to the 4:44 32 degrees of total advance 4:57 when I rev up the engine check the tire 5:00 I can see that we're a couple of degrees 5:01 off 5:23 so I go back and set the initial time to 5:25 get nine degrees 5:27 and then rev the engine up again to 5:29 check the advanced timing 5:31 now it's right on the Mark at 32 degrees 5:57 I checked the idle speed as it has 5:59 increased because of the advanced timing 6:02 and I adjust it back to about 900 RPM 6:06 by turning large bypass screw on the 6:08 side of the carburetor 6:12 [Music] 6:37 two end I'll double check the advanced 6:39 timing 6:41 which is still at 32 7:13 and that seems much better we the engine 7:15 seems a lot more responsive now that 7:17 we've got 7:18 actual proper timing set in this engine 7:21 um it turned out this would be static 7:23 timed at about nine degrees with this 7:25 distributor and then it Advanced out to 7:28 32 degrees 7:30 so 7:32 we're going to take this thing for test 7:33 bin and see how she feels now Test drive 7:36 [Music] 7:58 it's not a rocket ship by any means but 8:01 it feels much much better 8:16 shift points on the speedometer as far 8:18 as the mile per hour seems to match up 8:20 really well 8:23 I'm pretty happy with it for being a 8:25 devil and iron she's actually really 8:26 really responsive I can't complain one 8:28 bit 8:30 not much hesitation at all 8:42 not bad 8:46 for a double 09 8:50 it's carburetor scenes to have just the 8:52 right amount of Advance out of it 8:56 the distributor now that we've got it 8:57 timed properly 9:00 it just seems smooth as can be 9:07 and that's third indicator will shift to 9:09 Fourth 9:15 I like it 9:17 I really like it 9:19 for a double or nine even and I'm not a 9:22 big fan of devil and I 9:24 this thing drives it very very well 9:58 that's a wrap Closing thoughts 10:00 in reality this thing's ready to go 10:04 um but again as I mentioned 10:07 despite how really really well this car 10:10 runs right now even with a 34 Pick 3 10:14 carburetor and a you know a non-vacuum 10:16 advance distributor 10:18 I I'm I'm aghast at how well and how 10:21 smooth this thing runs currently but 10:22 just the same 10:24 uh it's still running a standard points 10:27 and condenser ignition 10:29 and it doesn't have a vacuum and we're 10:32 gonna Swap this out 10:35 in our next video we'll show you how to 10:37 swap out from a double09 to a 10:39 centrifugal Advanced distributor
