Desooting the intake preheating pipe of an aircooled VW
A blocked pre-heating pipe on a VW aircooled engine may be a major reason for stalling engines shortly after start, especially under humid and or cold weather conditions.
During the restoration of the engine it is quite often forgotten to decarbonize the pre-heating pipe of the intake pipe. You will certainly have heard or read about methods to 'decoke or desoot' this preheating pipe, whatever it is called.
I find it the easiest way to knock the preheating pipe with a hammer so that you 'generate' some trembling of the steel causing soot and rust to come off from the inside of the preheating pipe.
To ensure trembling (resonance) of the steel pipe you can better hold it in one hand and hammer it with your other hand . Do not tighten the pipe in a work bench since this will prevent the steel pipe to 'tremble'.
Knocking with the hammer may take about half an hour to gain a good result, so don't give up !! Do not knock too hard to avoid damages or dents in the pipe. Mind NOT to hammer too hard on the aluminium casted part either (which holds the intake pipe and the preheating pipe together) to avoid cracking of the aluminium. The video shows how much debris came out of this one pipe.
So this way of 'desooting' is worth doing in my opinion, rather than making holes in the pipe which have to be closed by welding afterwards.
Once the hammering operation is finished you can respray the entire intake pipe assembly with zinc spray so that is becomes a genuine look.
After re-installing the intake pipe on the engine you will notice that the left hand and right hand side of the preheating pipe will have the same temperature after the engine has been running for about 4 to 5 minutes from cold (or even in less time) !
Good luck !!!!

Classic VW Engine Rebuild, By Last Chance Auto Restore.com
We began with a dual port 1600 cc engine from a 1973 Volkswagen Beetle.
The engine ran with a miss and was smoking a bit . After performing a
compression test,(both wet and dry) , we determined the crankshaft and
bearings were fine.
We replaced the pistons, pots & rings. We had the valves redone and made
several upgrades along the way.....
Yaril's Volkswagen Type 3 - BRtv Episode 3
Imagine yourself back in the Do-Wop 1950s. Now picture what a young car
guy, hot rodder type, would look like. Then take that image, dip it in a
batter of Cuban heritage, add a good dose of upbringing and family values.
Follow that with a splash of love of all things vintage and cool, and
lastly add a great sense of style, attention to detail, and humility. Now
pull that person in the present time and drop him in Miami Florida. What
you might get, my not be too far off of Yaril Quintana.
Yaril is just about one the coolest and nicest people you can meet. He's
the owner of Yaril's Customs out of Miami Florida, and is the builder and
owner of this awesome VW Type 3. He's a hot rod builder and an incredible
craftsman, with award winning capabilities and an astounding sense of
attention to detail. His shop is as clean and as cool and anything else he
puts his name to. Just hanging out there, makes a normal person want to
run out, buy a junker and build it into a hot rod, or something as cool.
This video celebrates his awesome Squareback, and attempts to show a little
bit about the man himself, and what are the principles that drive the kind
of creativity that make a shop like his, a possibility, as well as a
realization to a life long dream.
Let me say again, you could almost not meet a nicer, cooler guy than Yaril
Quintana, with as much talent, humility, and just good core values, as the
ones that drive him.
We hope you enjoy this video. For more on this story and some cool pics

VW, CROSS FIRE,OIL INJECTED,MANIFOLD HEATER, AND OIL COOLER
THIS IS THE FINAL DESIGN AFTER OVER A YEAR OF TESTING. BESIDES A 10%
increase in HP, the manifold is now oil injected to eliminate any chance of
carb icing at any cold condition and benifits the engine by cooling the
oil and is returned to the valve covers where is again mists to cool the Exhaust valve stem and springs at this
point its about 100 degrees cooler. They are made in batches of 10 units
..they flow fuel extremely well and will work on any vw upright.including
buses and ghias. with clearance to spare.the runners are 1.1/4inch in
diameter .. and flow 1900 meters. of air .. more that enough for any
engine.made... really big engines flow about 1400m . No special alt or gen
brackets are necessary ..this manifold fits perfectly. Deposits are taken
by the oldest recieved first They come in silver ceramic coating only the
price is 575.00 dollars with a 100 percent refundable 100.00 dollar
1967 VW Type 3 Fastback: "Inge"
Portland, OR: excellent, nearly all-original 1967 VW Type 3 Fastback.
Third owner, has been with me for nearly 10 years. No rust beyond
superficial surface dings. Pan is 100% solid. Chrome is very good, though
has some minor areas of pitting. Never any sort of major accident (front
and rear are clean), though there is evidence of long-ago passenger side
door repair (done poorly). Glass is perfect. Motor is 98% original and "all
there." Original interior is excellent (no rips / tears; front seats could
use new foams), all correct trim pieces are there, dash is perfect.
Everything works but clock may need attention (regreasing, etc.) Runs,
drives, shifts, brakes wonderfully.
COMES WITH: original delivery papers and early records; original uber rare
*RED TYPE 3 WOLFSBURG FLOORMAT* though it is very well used and has always
had a hole at the heel near skinny pedal; red coco mats, a bit faded;
*extra set of correct Fastback popout window seals* (sourced from a donor
car; not NOS, but very good to excellent condition); original AM radio; NOS
German door seals; NOS Type 3 muffler; seals for turn signals and original
rear turn signal lenses. Also have small box of original parts.
NEEDS: has a slow oil leak on passenger side valve cover; possible new
battery (this one is new but has been driven so infrequently that it
doesn't crank well unless jumped); could use carb tuning or rebuilds and
general tune-up attention; needs new window rubber seals (front and rear);
could use new seals for front and rear trunks (I have one for rear.) I'd
also love to track down some original '67 Type 3 wheels and trim; these
chromies look nice from 10 ft away but the chrome is pretty weak and
starting to rust.
This car is not a show car (yet). It needs to live with a real Type 3 geek,
someone who will care for it and cherish it with the attention and love a
rare survivor like this deserves. I know in 10 years I am going to be very
regretful of this, but right now I do not have the means/time/skills to
maintain this wonderful car like it should be.
