I know that vw's have a hard time running when it's below freezing. Especially when it get's -40F here in Minnesota. I have an idea. What if, I were to make a box that contained a filter (most likely a cone type) that connected to the carb, and then have a flexible aluminum tube (like dryer vent but firmer) that connected to the normal outlet on the heater box (either driver's or passenger's). I may also add a few small holes that way the air going into the carb isnt really pressureized (may interfer with booster) and the air isnt too hot. As for cabin heating im not too concerned. On my old 71 baja i used  a high amp alt. and used a 2000 watt inverter, and a small 12.5 amp 1500 watt max electric ceramic heater with a built in fan. Went out on a fairly cold morning (around 20 degrees) and fired her up. when back inside, had breakfast, came out 20 mins later and waalaa! the inside was nie and toastee and there was no frost on the in or outside of the windows (there was actually ice on the outside). i used a big battery as well. does anyone else think my carb heating idea is a good thing, or bad?

also, i know stock, u use a solid core plug wire, with resistor plugs. can i use spiral core wires with normal plugs (same size, reach, heat range)? and what is the bolt pattern size for a '71 super beetle (4 bolt)?

Hi,

Well, We don't use resistor plugs in Beetles in Australia as the resistor is built in to the bakelite piece that connects to the top of the spark plug, and the rubber grommet fits over....

VWs also have a resistor in the top of the rotor button...

both these are because of the genuine wire spark plug leads....

 

An NGK spark plug used is B5HS... also W5AC Bosch or I always have used BERU German spark plugs... sold at most VW shops....

I also always use the genuine VW type leads, resisitor spark plug Caps and rubber boots... etc..

 

The VW wheel spacing isn't used by anyone else that I know of...

 

cheers

Answer to Your Question about the spark plugs

naturally it is OK to use the spiral spark plug leads...

and non resistor or resistor spark plugs...

 

I would think with spiral wire plug leads and non resistor spark plugs You may get some interference on Your Radio etc

from the spark plugs.. without any resisitance...

 

plus interfere with other radios TVs etc...

 

best of luck

Beetles used to have a preheater pipe for the carburetor

and a flap that was clicked down for the summer to close off the heated air...

some carburetors had two of these preheater pipes..

maybe the colder countries..??

Some were approx 20mm and the later ones were the normal heater size flexible hose...

most of these have been taken out years ago...

and the hole/s blocked off...

but I've seen a few with the holes still there... not good for the summer...

I didn't take My beetle out in the -5C cold weather this winter

so I'm not sure how good My heater is...

its certainly OK at 10C or 50F weather, or warmer...

 

but it did take a few minutes to warm up....

I expected the heater to work immediately, after the car had been sitting for an hour one cold day....

 

I thought I had a pic of the heater pickup tube...

but must have been deleted....

 

cheers
