For the problem with the 80 too small holes in the back muffler, there is a super simple solution. I took a drilling machine and made 2 one inch holes through the left and right outlet of the muffler into the wall of the two pipe ends. The muffler is not much louder. You can start with a hole with 1...

"I'm not confident in my abilities to get exactly the right amount of material removed, in the right place, 4 times for each needle. I'd feel much more comfortable buying needles that are close, even if they are not perfect. Close is good enough in this case." You are right. SU or Burlen offers dif...

I think the missfiring can (?) caused by lean mixture. The detect this, you need a wideband lambda measuring system in the car. You have to measure the mixture at driving, NOT at iddle. IF (?) the air filter, the motor and the exhaust system is original and the original carb-needles are mounted, you...

Why do you ask an idiot like a car-machanic about advance or retard ? Read a book like "Otto-Motor Management" from BOSCH ! Written from a lot of high qualified car engineers. In this book is a written, that before programmable ignitions, nearly every motor between 1960 und 1980 had an ADVANCE capsu...

I am driving a EV12 with a 6,0L motor from an XJ81 and have 20 years of experince with carb-tuning and needle shaping. The car has now 4 originial EV12 Stromberg carbs and 4 taylor-made needles. The correct AFR for idle is 12.5 to 14:1. The correct AFR for light cruise can be AFR 15 - 17: 1. I am dr...

What is the price of such a rebuilding of a power steering rack ?

Mybe (?) each of the front wheels have worn out uneaven. Change the wheels from front to back and the back wheels to the front. Make again a test-drive on a bad street. Maybe the problems disappeare. I have bought a Gunsons trackrite tool. A german oldtimer magazine has compared the results with a p...

Years ago I met a guy, who was a car ingeneer at Volkswagen for safety belts and air bags. He immediately told me, that the normal steel aprts of the belt system beside the seats are too long. They touch the 'bone of the hip' if you have a crach and will destroy/crack the bone. He told my to mount a...

"Ive just this morning had it on the gas analyser it now ticking over at lambda .993 and CO at 2.10 at 2000rpm again lambda .987 and CO at 1.86. When i was running on Stromberg's it would not run under 6% CO when on SU carbs it needed to be at least 4.5% the lambda was never anyway near 1.0 a vast i...

I am far away to be a spezialist for shimmng hubs. Is it possible, that there shall be an endfloat, because , if the bearing is becomming warm when driving, the endfloat is becomming zero or will become a pre-load ?

The mixter is depending on the circular cleft betwwen the needle and the jet. If you adjust the mixture lean at throttle,this ich changing the mixture at part or full throttle not so much. Maybe (?) the needle or the jets are worn. Then the cleft is becommimg bigger and the mixture is becomming too ...

hhhhhhhhhhhhhhhhhh

I had the same problem. A rubber / plastic piston-seal of the brake-piston of the brake-cylinder, on which you press the food was damaged and the brake-liquid moved from one circuit the the second circuit. Very quick the lower 'bottle' was overfilled und the upper 'bottle' was empty. A damaged (rust...

At most of the time, my 6,0L HE motor at small part throttle and medium part throttel is running with a lambda of roundabout 1,05 to 1.10. When crusing with this mixture, an injectet car can't take much less gas. 5% les would be a great number. My car is driving when crusing with roundabout 18 - 20 ...

"Also complicating things, I’m challenging myself to make it a “bolt-on” upgrade that will work on any efi V12. The secret is liquid (not gas) injection, at least 10% more power that with petrol, 50% reduction in fuel costs and Euro 5 or better emissions. Can’t do that with carbs. So imo, if you ar...

Hello Colin, "I find your comments very enlightening as I was also considering injection, however straight pipes to the airbox and possibly SU's or a setup on a rolling road for the Strombergs looks like a better option all being considered." If you mount two pipes with a bigger diamter to the airfi...

I have mounted the Getrag 265 with 5 gears. The fifth is 1: 0,81, therefore an "overdrive".

I am driving a Series III since 20 years. If you want to improve the power output an the reliability, make these changes: 1. Don't do EFI. It is a long way, until it will work good. Marek has done it. His motor is running very good But Marek is intelligent, has a lot of knowledge and experience. 99%...

"I wondered whether it would be possible to fit a slightly larger diameter slave cylinder to improve the hydraulic gearing giving a lighter pedal? I would rather not mess with the master cylinder as thats a lot of work now as everything is fitted in that area. I understand this would increase the d...

"I now work on the basis that these old tech engines need the following AFRs (as a guideline): 0-30% engine load: AFR 13 (this is overrun / engine braking conditions) 30 - 55% : AFR 16 (light cruise) 55 - 75%: AFR 14 (maintaining speed up a slight hill) 75 - 100: AFR 13 (basically full throttle)" I...
