That's not a bad starting point for the timing, but it should be able to take 14 degrees at 1000 rpm with the vacuum advance pipe disconnected and blocked. That would give you more low down power up hills. Hope the thud's not the engine falling out  David I've set the timing for 10degrees BTDC at 1000RPM. Will see how she gets on like that, couldn't hear any pinking up the hill, but I'm not 100% sure on what it's meant to sound like. I'm sure my father in law can confirm next time I see him. Noticed a thud coming from the engine bay during gear changes, I believe this is the servo moving, so will see if I can make a temporary support to confirm this. -Andrew PS Sorry for the lack of photos! |

lol I hope it's not the engine too! Also I just realized in the shower this morning that I blocked off the vac advance pipe while it was attached to the carb and not the dizzy...  -Andrew |

That's correct! You block it off to avoid air leaking into the carb. Maybe you need a cold shower lol I hope it's not the engine too! Also I just realized in the shower this morning that I blocked off the vac advance pipe while it was attached to the carb and not the dizzy... -Andrew |

Is it? I thought the idea was to block off the dizzy side?
As for advancing it to 14 degrees, it seemed to be on 12.5ish when I first started.
Like I said, will trial it at 10 degrees. If it's not going so well I'll go back to 12.5.

When you disconnect the vacuum pipe at the distributor end the vacuum advance no longer operates the distributor but as soon as the throttle is moved off its idle setting it draws air into the engine upsetting the mixture. So you need to either plug the vacuum tube still connected to the carb or the carb vacuum take off if you leave it attached to just the distributor. The original timing with leaded fuel was 12 degrees stroboscopic at 600rpm or 15 degrees at 1000rpm. You will probably need to allow a couple of degrees less to take into account the unleaded fuel. If you start at 10 just wind it up a degree at the time to get the best result with no pinking then knock it back a degree. David Is it? I thought the idea was to block off the dizzy side?

Thanks for that. I went on 10 degrees at 1000RPM, as that's what my Haynes Princess manual says (as some, including Tommy think my engine is from a Princess).
When you say knock it back a degree, do you mean if I get no pinking at say 13, take it back to 12? (or 14?).
Also what does pinking sound like? I've read/been told it's like a front loader full of marbles. Because when I try to listen for it, all I get is the exhaust.

Difficult to explain what it sounds like but I still like the analogy of shaking marbles in a tin. The repetition of the sound is directly proportional to the engine speed, it can be 1,2,3 or all 4 cylinders knocking. You hear it best at lower engine speeds (up to say 3,000 rpm) under high load. As you ease off the throttle it goes away and you can make it louder by accelerating harder. It's not like an exhaust noise but more like the sound of a hammer hitting the crankshaft. Unfortunately I've not been able to find a good example on Youtube but you will know it when you hear it (I did it's intuitive). If you read the recognised experts on MGB timing the overall conclusion is that the optimum timing varies considerably, by quite a few degrees, from one engine to another apparently identical. I know that's not much help but it's the way it is. The most crucial setting is not the idle advance but the maximum advance (without the vacuum advance) when the engine is working under high load above 3000 rpm but it is difficult to hear knocking on these engines above 4000 rpm. First thing to check again is that the distributor mechanical advance is functioning properly and the springs are not tired. The timing has a much greater influence on performance than the carb setting within reason). Once you are happy the distributor is working properly you can advance the engine ignition timing until you hear pinking and then retard it 1-2 degrees. There is little danger in setting the timing advanced by 10 degrees on a hot engine for just a few minutes so you know what sound to listen for. Back off the throttle as soon as you hear the pinking though! regards David Thanks for that.

Thanks again David.
Not too much to report on since this, had a drive this weekend around town and she seemed fine, might advance it another degree and see how we go with that.
Manage to give myself a nastey little burn from the manifold while trying to look for a rattle coming from the engine bay (radiator cowl I think). So just a friendly reminder the be careful, chaps!

Good to hear it's running well. Sorry about the burn, easily done, now you are a branded Landcrab owner Thanks again David.

Not much going on with Wendy.
Noticed a small hole along one of the seams on the driver's seat, so should get that looked at before it gets worse.
Had to do a hill start while going into my driveway, car stalled. Not sure why, so shall keep my eye on things.

Zero work done on the car. I did some on the Rover 600, when the passenger side window came off it's runner (got it back on, but have been too afraid to try it out, as we're heading into winter now).
Took my (step) father in law out for a spin in her, and he had a quick drive around the block. He enjoyed it very much.
Have been dreaming about gettting a 6/110 (I'm sure Chris wouldn't approve lol)

Why? Big comfy old barge capable of a quite astonishing turn of speed. Handling isn't exactly its strongest suite, with cart springs at the back and a steering box at the front - even so, a highly luxurious way for a gentleman and his family to proceed.
(Power steering is really light - the Mrs might like it!)

Quote from Wikipedia "The Wolseley remained in production as the Wolseley 6/110 through to 1968. Many police officers consider the "6/110" as the finest "area car" ever employed by the London Metropolitan Police Force." I still think it and its sisters Austin Westminster and VDP Princess are fine looking cars in a conventional sort of way. Somehow the Farina styling works much better for me than for the smaller Austin Cambridge / Morris Oxford /Wolseley/Riley/MGs. David Why?

I've set the timing for 10degrees BTDC at 1000RPM.
