1972 Volkswagen Beetle Repair Question
Mileage: 178,000 miles.
Should my intake manifold be very hot to the touch?
Asked by buggyloverAnswer
it should be warm but not too hot. how does it run??
Roy
Runs fine no missing but sometimes it is hard to start after the engine gets hot.
it could be vapor lock or something with the carb. have you had it to a shop to check it out.
off the top of my head, i would check the timing first.
Roy
Just had timing and carb set at shop. Could running the engine without the lid cause this problem?
TIMING PERFECT?
COULD YOUR MECHANICAL ADVANCE SPRING(S) BE BROKE AND NOW THERE IS NO ADVANCE?
MAYBE IT'S POINT ADJUSTMENTS?
RID YOURSELF OF THAT PROBLEM!
I INSTALLED THIS SET UP AND THEIR FLAMETHROWER COIL INTO MY '46 WILLYS JEEP---I HAVE SEEN OTHER VEHICLES USING THEM TOO....I WISH I HAD DISCOVERED THEM EARLIER, THIS SET-UP REALLY MAKES ME GRIN!

IT'S EZ AND QUICK TO INSTALL, I KEEP MY OLD "PLATE" W/ MY POINTS UNDER MY BACK SEAT, JUST IN CASE MY "IGNITOR SYSTEM" WERE TO FAIL.....I COULD HAVE IT BACK TOGETHER AND TEMPORARILY TIMED BY EAR IN LESS THAN 5 MINUTES
READ THE INSTRUCTIONS CONCERNING THE NEED FOR A BALLAST RESISTOR OR RESISTANCE WIRE....MINE ORIGINALLY USED A BALLAST RESISTOR USING POINTS, I LEFT IT ON THERE, BUT JUST "PIGGYBACKED" THE OTHER TERMINAL, SHOULD I NEED TO REVERT BACK, I WILL MOVE THE WIRE BACK TO IT'S ORIGINAL TERMINAL
HERE'S SOME PICS OF MINE
WHACHU THINK?
THE MEDIC
I RECKON I COULDA SAID THAT BETTER THE 1ST TIME
SPRING BROKE---STAYS ADVANCED (EVEN AT IDLE)
UNLESS YOU SEE YOUR TIMING IS OFF!---THEN YOU (UNKNOWINGLY) "RESET IT" CORRECTLY----REALLY, NOW,
...IT'S ADVANCED FULLY, BUT NOW IT'S SET BACK TO CORRECT IDLE TIMING......BUT STILL IS UNABLE TO ADVANCE MORE (THE WEIGHTS REMAIN SLUNG OUTWARD, UNABLE TO RETURN).......AS YOU ACCELERATE IT WILL "HOLD BACK"
VERIFY YOUR ADVANCES WORK
IF YOU HAVE A VACUUM ADVANCE, PLUG IT OFF. TEST FOR ADVANCE BY THROTTLING THE ENGINE...YOUR TIMING MARKS SHOULD ADVANCE AS YOU GO HIGHER, OFF OF THE ORIGINAL TIMING MARK (WATCHING WITH A TIMING GUN)
YOU CAN ALSO HOOK MANIFOLD VACUUM (NOT PORTED VACUUM) EVER SO SLOWLY TO THE VACUUM LINE N.IPPLE ON YOUR DISTRIBUTOR.....YOU WILL SEE THE TIMING MARK JUMP (ADVANCE) IF IT IS WORKING RIGHT
THIS CAN BE DONE WITH A VACUUM GUN TOO---BUT, WHY BUY ONE WHEN YOU ALREADY HAVE VACUUM AVAILABLE?
I'M NOT A VW KINDA GUY---I HAVE DEALT WITH THE MECHANICAL ADVANCE SPRINGS BREAKING ON OLD PRESTOLITE JEEP CJ DISTRIBUTORS MANY TIMES.....WHICH WE USUALLY UPGRADE TO THE LATER MOTORCRAFT DISTRIBUTOR
AS FAR AS FUEL DEPRIVATION POSSIBILITIES
---WHEN IT ACTS UP, IMMEDIATELY GIVE IT A SHOT OF ETHER OR FUEL DOWN THE CARB, SHOULD IT BUST OFF NORMALLY OR EVEN TRIES A LITTLE HARDER THAN BEFORE....IT COULD BE A FUEL ISSUE AND NOT AN IGNITION ISSUE
KEEP US INFORMED
