It's all about timing you know...

Hey Guys.

I've read the Haynes Manual, I've searched through the 368 pages of some bloody CD I bought and now I'm thoroughly confused.

If I'm running a 2.25L petrol Series III, with a weber carb and on unleaded with the Lead Replacement stuff getting added (by me at the rip-off feckin fuel stations - DID YOU KNOW I SPENT £113.46 FILLING UP MY DISCO II last week for feck's sake!!!)...sorry starting a rant there.

My question is, what the heck should I set the timing at? Some say 3 degrees BTDC and others as much as 6 degrees ATDC. I've got a timing light, so it's easy enough to feck around with it, but I'd like to know for sure what it should be at before I start any other work on the wee soul!

cheers

On a engine that old set it by ear because everything moves
or for 95octain i have been told 6deg btdc if you want numbers.

I see! That sounds good. It's a 1972 car, but the distributor I found when I renewed the points, condenser and plugs are from the 1978 model onwards.

Also I use the cheapest unleaded I can find so I'm not sure what octane that is. Will these factors change anything?

Basically I'm trying to eliminate lumpy idling, cutting out occasionally and so on, by getting the timing as good as possible before I strip and clean and reset the carb. If only I could find a manual for that weber carb I've been through google a dozen times!

Any more thoughts on the above?

Many thanks

yep as clivee ses do it by ear,dunt need a strobe light or crap like that ,mek sure your fuel mixture and tickovers set right

I think yel find that if yer carb is all to fook then yel never get yer timing right by ear, as it huffs and puffs it's gona throw the advance retard all over the place it needs to be running perfect and the guys are right do it by ear.

Find a big fookin hill, advance the timing untill it pinks on the hill then back it off a bit at a time until it dunt, sorted.

You can fook about wif a carb for ages and still not get it to work right, without the kit to see what you are doing, you can get it running what you think is right only to lean off on the road, or fail mot, see if a friendly mot guy will let you stick a probe up it's arse and play wif it there.

If it dunt respond, then either fook about wif a clean, checking diaphrams and gasket and so on or get another one, which sometimes is the best road.

I reckon Slobs method is easier.
