Can anybody tell me if the heat riser tubes on a type 1 inlet manifold are 1 piece of tubing that runs right through the cast aluminium section or if they are 2 pieces of tubing that go in each side of the aluninium section with a hole through the middle connecting them.
I want to fix up the manifold on my beetle (not keen on $160 plus for a newy) and just wanted a heads-up before I break out the grinding implements.
Cheers

before you break into grind and cut mode get a drill and an old piece of pipe snake and sharpen the end ,whack it in the drill and work it thru the carbon ...if you cant find a snake try a piece of flex curtain rod spring stuff .saves a lot of grief later:beer:beer:beer

Try an old clutch cable in ur high speed drill. It will depend on the severity of the impaction- I've never had much luck!
For me it has been nec to cut at the dog-legs going to the exhaust BUT NOT RIGHT THRU then bend them out of the way for a LONG drill bit to go thru the carbon.
A tip: Mount the manifold & tack weld the cuts before re-welding properly with the manifold on a bench. It makes lining up the manifold bolts easier!

I found an easier way....................just fit twin Kadrons !!!🙅

i cleaned mine out years ago when i still had a single carb set up by sitting it upside down and filling it with a very harsh cleaner (was called activeshift is almost acid LOL) overnight and the clutch cable in the drill trick the next day worked a treat
the standard ones were one piece but alot of after market replacements are in 2 pieces so they can be fitted and removed more easily
why do i see so many beetles with them cut off:duh
they barely stop icing when clean with a standard exhaust:o

Craig,
Will they work on a 1300twinport or would they be to much?

Never tried ! I think they would, but probably not worth the expense etc for the minimal gain. Could always fit 1600 p&b's ??

I did this last week oxy, hammer and a lot of patience. I found heating (red hot) and quenching helped loosen deposits.

The heat riser tubes are nearly always blocked, so they rarely work and are very difficult to clean. In winter I used to fit a warm air pipe from behind the engine to the air cleaner. The icing up and the coughing and spluttering stopped. Beetles have a provision for warm air intake and if yours is not connected, then do so in winter.
