I approached several of the usual suppliers in the UK for mud flaps / mud guards / splash guards - those protective shields mounted behind the wheels to prevent water/mud/sand/stones/molten tar/oil etc from being projected onto the body of the car. It is somewhat of a surprise that mud flaps are not...

When re-commissioning a friend's car, we purchased a new sender AND gauge from the co now representing Smiths. The sender I received looked correct physically, but it was a mismatch against the gauge. It turned out the Gauge was wrong. The second shipment they sent was correct. I'm saying that perha...

For those who still remain convinced that Ported Vacuum is what is needed, here is another solution that will effectively provide the same as ported vacuum but does not require removal of carbs, drilling them, risk them being messed up, fitting ported tappings, refitting them, re-balancing them... V...

Or maybe you agree with much thats already been said in the subject....

Quite right Steve, absolutely.

Another opinion on this matter This article confirms much of what I’m saying. The only area where I would like to get clarity from John Hinckley (the author of the article) is that he refers to idle mixtures as being “lean”: "is that lean mixtures, such as at idle and steady highway cruise, " Idle ...

After all this, I'm hoping for a glimmer of understanding why Jerome's method is not a good method..... UNLESS.... His engine is configured with a vacuum advance module on the distributor and its vacuum line is connected to MANIFOLD vacuum. Question 8: WHY ???????? Question 8: WHY ???????? So, lets...

Crikey!!

It's gorn right over me now.

Ummm, only saw this after I hit "submit". Clearly I did not succeed.

Jerome, this approach is wrong, wrong, wrong and I will make sure to explain WHY (actually I already have :geek: ), specifically on this matter, after questions 7 have been answered and I'm sure the answer will NOT be over your head. Hint: 7.2 relates to this matter... Jerome, if you now read my pr...

When I retard the engine timing below 12º, idle rpm drops. WHY#7.1? When I advance engine timing to more than 12º, idle speed increases to beyond 800rpm WHY #7.2 Found a few moments.... 7.1 : When you retard timing, the fire starts too late, fire burns nicely by the time the piston is well on its w...

if u don’t have a ported vacuum tapping, manifold vacuum can be used. Thank you Colin. May I add please? For the benefits ported vacuum advance may hold, it certainly is not worth the cost and risk of: - removing the carbs - having them drilled and fitted for ported vacuum (hoping they don't get dr...

Gents, Tomorrow, I'm off the the bush as a volunteer for the "Tour de Tuli" cycling event. I'm coming back on the 7th, so please don't stress if I don't reply in this time. Colin, I don't have time to also address your latest post because I have run out of time. I do believe that my posting above ma...

jagwit I think that Jerrl [ nearly spelt his nme right] raises a very valid observation, plus his honesty is to be applauded Idling the engine............... loosen distibutor clamp then swivel right to left and back again, repaet and repeat until the sweet spot is found !!!! Yes its at idle rpm bu...

It was my understanding that one way of finding the "proper" timing (adv BTDC - when you don't know the advised figure) was to rotate the dizzy one way and/or the other to find the max rpm position at tickover. In other words, when you advance past this position, the tickover speed will reduce. Whe...

Question 7: Right we have "our engine" idling nicely at 800RPM with 12ºBTDC. No vacuum retard or vacuum advance connected. I trust you will now keep in mind that this 12ºBTDC is 12º not because this is what is needed at idle, but this is the timing needed when the engine goes from "idle" to full thr...

When talking about efficiency we maybe need to be clear about what it is that we are trying to be efficient about. E.g.1: If the purpose of a car is to move, at idle (stationary) efficiency is zero or worse, more efficient if u turned yr engine off. Burning petrol to overcome parasitic loads, frict...
