Its a condenser. It should be conected to the distibutor. Deffinately put it back on cos you won't go far without it.

Im in the UK for Christmas. Its so nice to see so many small cars on the road here. Typicaly my mothers little Vauxhal Corsa with a 1 litre engine. But there are many similar sized cars to choose from. My favorite being the new Fiat 500. But what really amazed me is the efficiency of all engines here. The old man has a new BMW 5 series diesel. Now I know BMW is a dirty word on this forum but he regularly gets between 45 and 48 mpg on short trips (less than 20 miles). I think thats pretty fantastic for a big family car.

I found on mine that it was the pointer that had distorted and was rubbing against the dial face. I just roved the clear plastic cover and cut the pointer down a touch. Job Done!

I wonder if the float valve is sticking? Seriously, how cold is it where you are? Ive never heard of engine parts freezing. Least of all a carb.

Me Too! If only for the colour. Garanteed 15% better mpg? Quite a statment. Subject to conditions I'm sure.... I'm more interested in your last post about the heads. Its becoming clear to me that when I next rebuild I need to go over every part with a finetooth comb. Would love to fix all these things and say for sure that I have done all that can be done to ensure a premium function. If I can do this then I will treat myself to those leads.

And it always steals the new ones. Never the old ones with holes in them. My wife and I both hate sorting socks. We have a big chest at the foot of our bed that we just throw them into. She has been known to wear an ankle sock on one foot and a wooly ski sock on the other.

I consider screwdrivers to be a consumable item. Even the good ones crap out in the end. Generally because they are one of the most abused tools in a garage. Plus people seem to have a habit of borrowing them and not giving them back. Speaking of losing stuff. Where do all the damn pencils and marker pens go?!

OUCH!

Cable could be damaged or kinked somewhere. Maybe remove the cable, check it out degrease and relube. Also maybe try a sturdier spring on the throttle linkage. Last I had this problem I sprayed heaps of lube into the cable housing and removed a few coils from the spring. A bit agricultural but it worked.

my figures say 6hp. Thats an extra 10% for me! I reckon thats worth the effort. Plus I'm stoked that the idea actually works! That was a 3700hp engine so they gained nearly 20%! Thats not bad.

Sweet! Not so crazy after all!!

This doesn't make sense to me. Either they both work or both do not.....? The theory you are suggesting is exactly the same mechanical setup. Not sure about the perpetual motion thing. The exhaust has energy. Its just not harnessed. (none of my comments are fact or based on knowledge. only speculation) The way I see it is this: Cool air and fuel enter the cylinder. This explodes and forces the piston down. Most of the energy is expended here but not all. What exits the cylinder is a hot expanding gas that still has its own energy. This is the part that is currently wasted. The question is: Is there enough energy left to convert back into a few hp?

Einstein was a patent's clerk! And I'm just a wooden boatbuilder.

I thought about the fixed drive aspect and wondered if some sort of rachet system could be used like on the hub of a push bike. Or maybe some sort of clutch system. My engine is 1600cc. At idle it does 900rpm so it would be breathing 720 litres per minute of air? Thats a lot of hot gas not being harnessed right now. The thing I like about this concept is that it is not adding power but recycling unused power.

Not sure where to post this or if this is the right place to post but here goes: Turbo's and superchargers put a lot of extra strain on an engine and use more fuel but are a good way of extracting more power out of a smaller engine. At least this is my understanding. But what I was thinking was this: What if you were to rig up a super charger unit to work in reverse. In other words use the exhaust to drive the supercharger and put that exhaust energy back into the pully/crankshaft. Sort of a backwards turbo/supercharger Could this be a good way of recycling the exhaust energy with out adding extra strain to the engine? Genius? or Crackpot?

Them is mighty big holes! What size engine was the weber set up for?

Thanks.

What pressure should I be reading for an EA71?

Can I use the heads from an EA81 on a EA71 block? The bore is the same on both blocks but I'm guessing the valves are bigger? Or is it the cams that differ?

I have spoken to a pertronix dealer here who has what I need but he wants nearly $400 kiwi dollors for it! I think can can use a dizzy from a later EA71 but as yet have not found one. 200bhp! I'd be very happy just to get 80

How do I do This?

Cool idea! Its a 79 dl sedan. I'll keep a lookout for one. Where does the tack sender live?

Ah Ha! So now we get to the dirty details. Doug, did you read my threads named 'knock or preigition' and 'my suspect wrist pin'? Your post about the worn piston got me thinking about my strange noises. As did the post about my bores. What did those people have to say about them? Is it possible to rebuild this block for the third time or should I be throwing it away? I do have access to oversize pistons and bearings etc. Great new avatar by the way!

Cool. Thanks to all for the sound advice. The best news is I already have a Mitutoyo digital caliper! Its in my parents garage in England. And guess where I'm headed for Christmas! Never really heard of Mitutoyo until now and i'm happy to hear its a reliable brand. I seem to remember buying them for about $25 so I think I did OK there. Mind you the guy I bought them off was certainly of the dubious nature.

Sounds like its still not getting enough fuel. Have you fiddled with the idle mixture screw yet? If not, then try it. Anticlockwise will give you more fuel at idle. when the engine is warm set the trottle screw so that you have about 900rpm. Then turn the idle screw anticlockwise untill the rpm starts to drop, then wind it back in a little. Do you have a workshop manual?
