A friend of mine has just bought an old LT35 horse box. He has been told it has either a CH or CL 2 litre petrol engine. He says it is running rough, but it drove home the 200 miles ok after he bought it.
I suggested he did all the usual things & change the oil, filters, plugs, points (that takes me back) etc. He has done all the above except the points. This made no difference & the pugs he took out were black, he says it is doing 10 - 15 mpg. The dealer asked what distributor it had, as he couldn't see any marks he removed it & then found the Bosch marking. So he now has new points ready to fit but the ignition timming is lost as he didn't mark up anything before removing the distributor. Haynes don't list a manual so I wondered if any of the back roomers had any info on restoring the ignition timming on this engine. Also does anyone know if this engine can run on unleaded without modification, he has been running LRP in it so far.
Thanks.

Fit the new points and set the gap correctly. A dwell meter is best, but if you don't have one use a feeler gauge.
Turn the crankshaft clockwise, noting which way the distributor cam rotates, until the timing marks on the pulley and the casing are aligned.
Remove the HT king lead from the distributor cap and wedge it against the engine. This will prevent it from sparking.
Slacken the distributor, switch on the ignition and connect a test lamp between coil '-' and battery '-'.
Gently and very slowly move the distributor against the normal direction of rotation until the lamp illuminates. As soon as you reach this point the points are just opening and the HT spark will occur.
Double check by rotating the engine one complete turn. Your lamp should switch on and off, but should come on just as the timing marks align again.
This is called static timing and does not take into account centrifugal or vacuum advance. It should however be more than good enough to get the engine running, and if you've done it correctly you won't be more than a couple of degrees out in any case.....

Thanks very much for that Railroad.
He is picking me up Sunday to see if we can get it going.
I have an old strobe that probably still works, although i've not used it for quite a few years.
Do you know the procedure for dynamic timing ? I don't surpose it will make a great deal of difference to the engines efficiency, but with petrol prices soaring, every little helps.
Do you know if it can be run on unleaded ?

Hi, I can't help you with your specific timing problem but I thought I'd let you know that there WAS a Haynes manual published that covered the petrol (not diesel though) versions of the early "box shape" LT35 vans like yours! I have a copy and it has lots of info about the engine so I'd recommend having a look on Amazon, Ebay or other site for it. It is often listed as "LT 35" rather than "LT35", so try both when looking.
Also, a bit of a plug here (I hope no-one minds?!?), but I am just about to launch a brand new forum/message board specifically for owners of VW LT35's (both old and new shapes) which I hope will include lots of useful information and links to parts suppliers for these very popular vans. If you have a similar question like this in the future you may find your answer there! It will be strictly non-profit making and will be up and running in the next couple of weeks at....

I hope this helps,

all the vw's iv worked on have had a mark on the flywheel "0" for tdc and "v" for xx timing mark, if thats the case just line up the light to the "v"
for refitting the dizzy...turn over the engine so that the cam belt marks line up , then fit the dizzy with the rotor pointing at notch in the top of the casing
appologies if those marks arent there on a LT , but most other vw's have them so i expect it will

Thanks for your help. It was a friends van & he did eventually get hold of a Haynes manual.
I statically timed it as per the manual & steveo's explanation above. Started first time.
