Timing

Thanks guys,

That has given me a lot to think about. The engine itself is less than 3000 miles old, still brand new. The cooling system is close to 100%, my only problem is that I don't have those sealing rings that seal up behind the spark plug, I'm getting a new set of HT leds which will have them. Forgive my lack of lingo, but what does WOT stand for? I have retarded my ignition to about 3 degrees btdc, as I have a single vacuum dual advance dizzy, this has helped. But my only problem is that the fuel I'm running is the highest octane available in my country, it's 97 (I think RON), I might try an octane booster additive, could those help?

I also suspect a higher than normal compression, the guy who built it said the heads (originally 1300) had been opened up, but never said by how much. As for the carbon build up, is there any way to clear it away within a strip down? Could correcting mixture and going for a long trip free the carbon up?

Thanks Regards Kevin

Kevin, first off get those sealing pieces NOW,not later....without those seals you are losing pressure of the cooling air, and in turn you lose *alot* of cooling straight out those holes...they may look small and insignificant, but so does the "Hoover bit"....stop messing with the timing till you fix everything else....too far retarded will cause you to run hotter than normal...you are most likely overheating your heads due to the loss of cooling performance....get those seals...they are not for decoration....cooling for the heads is the

*MOST* critical task the cooling system performs.... JT

Wide Open Throttle (Pedal to the Metal) or gas pedal all the way down to the floor. :-)

You could give us some more info on this engine. What pistons are being used, their width and if they are flat-topped or have recesses? Is the camshaft stock? Is that distributor set up for an auto-stick trans, or manual trans, or a singleport engine?

Correct me if I am wrong............. I always think that 1300 heads are singleport heads, but I think you said this is a dual port engine. Carb is a 34PICT-3 (I wonder if adjusting or opening up the accel nozzle might help some). I think the engine might be running a little lean at part throttle.

********************* OH and are there any vacuum leaks, some might occur when you step on the gas pedal and the cable pulls on the carb. And are you sure you are using the correct timing marks on the pulley and case?

I hope I remember things correctly. :-) later, dave

...............I think that I like nappi laudassa the best. Of course, without Bill Merrill here, we don't know for sure what you're teaching us 'mericuns to say...............LOL

I didn't build the engine myself, but from what I have gathered it consists of the following: It is a 1600 (flat top stock pistons), with 1300 dual port heads opened up for 1600 jugs (not sure exactly of the compression ratio because of this). I live in south Africa and over here we had both 1600 and

1300 dual port engines. The carb is at the moment a 30 pict2, which is fitted via an adaptor plate. I 34 pict carb is stock for this setup, but I'm still waiting for it!

The dizzy which is a SVDA is setup for a stock 1978 manual bug, I've never seen an auto-stick in South Africa. The camshaft isn't stock, I suspect it is this combined with the opened up heads giving me this pinging headache! The camshaft to my knowledge is has a 276 duration with I assume a stock lift. That'll teach me for getting a non-stock engine!

As for those plugs, I agree they are important otherwise they wouldn't be there but why I haven't rushed is that I can't feel any air coming out of the holes. So I figured the it wasn't losing that much. My other problem is that the engine doesn't have the flaps or thermostat installed. I realise their importance but to find ones in this country is near impossible.

Hope this helps. Regards Kevin

maybe Bob Hoover can step in with a link or cut and paste of his writings on teh cooling system...(or you can google "veedubber)...it works on *pressure* you are losing pressure(and air) *above* the hot head....this leads to less cooling air going over the head, and cooling it....they are vital...it only takes a small leak(say *one* missing sparkplug seal) to really upset the cooling system....get those seals as soon as possible, and in the meantime break out the fix all.....DUCT TAPE!!!!! JT

To clarify, that is in badly translated english: the throttle foot in = the engine compartment.

Thinking about it now, you have a point! I don't use the car often, but I think before it gets used again I'll plug those holes up. I guess it's similar to a hole in a water pipe? A little hole results in a great loss of pressure.

Regards Kevin

Oh yea, right....

But I *have* performed some very interesting.. umm.. acrobatic moves in a beetle before... back when I was young and limber.. ;)

And just how many breathes does that take to say? LOL

I assume you mean the black rubber air seals. THOSE ARE IMPORTANT. You lose a lot of cooling air if those are out of place.

WOT = Wide Open Throttle

97 RON is quite high. That should take care of most engines, but most people will never think about the ramifications of their "upgrades" until afterwards.

I would not expect a significant amount of buildup in just 3000 miles. I'm assuming that it was clean at mile zero, however.

yes do plug those holes....yes *kinda* similar to a water leak....either way don't cook your engine....*ALL* cooling tin and seals are vital to an aircooled engine.... JT

...silly me... whe I saw little hole in a water pipe...I thought of a carb... =-)
