Can anyone identify this engine?

Eng. No. D1 086665

I think it might be a 1972/73 1200.

It is fitted to a 1969 Bug

Measures 51cm across from head to head. Runs a 30pict carby and single port. Just want to find out so I can get the correct tune up specs. The pulley only has one notch in it - should I be timing it to this mark ?

Cheers
Dave

Would the correct tappet clearance be 6 thou on this engine?

yep cold most likely a 1500 and the single pully mark is top dead center so with a degree pully you would tune it at 7% advance now dont hole me to it but thats about 10 mm from tdc🤪

That engine number comes up as a 1973 model engine
made from 1 aug 1972 to 31st july 1973
and a 1200 ...???

I don't know where it would have came from...
1200 engined beetles are common in Europe and the UK..

but Not in Australia in 1973..??

its should be 7 1/2 degrees with a vacuum distributor...

but usually they would have two marks...??
so, it can only be timed with that TDC mark...

what are the numbers on the distributor?

Yes, .15mm or .006" inlet and exhaust for D type 1200 engines. from 1966>

cheers

Yeah seems a strange number - like you say it indicates an early 70s 1200. The dizzy number is 113 905 205K.

Does it make any difference if I static time the engine? There is only 1 mark on the pulley so I have just timed it (static) to that but seems abit sluggish and has the odd backfire, mainly when cold.

vac advance dissys are fine to statically time

009s u can statically time to get the engine running but they need to be timed properly with a timing gun to max out at 30*

btw your crazy engine number isnt so crazy
someone has stamped that 1 in front of the original engine number
god only knows why

Hi Big Dave.
This engine looks quite like my first 1500 (1970) beetle.
I think you may find on the front end of the pulley (closest to you) a groove which it TDC. The mark on the rear of the pulley is the timing mark.
I could be wrong but that's how I timed the 1500 and I did it statically.

Thanks Simon but both marks are the same.

The engine is a single port 1200 so I am not expecting anything more than ordinary performance but if I advance the timing a tad will that make it at least abit more responsive and rev out more instead of dying?
Cheers

Dave, sorry I couldn't help more.
My previous 1500 didn't have a notch on the front of the pulley either, just the rear timing mark; that's where I timed it.
Good luck.

wasnt the d for industrial engines? think i remember reading that once and would make sense being a smaller motor i think some of these motors had magnetos too

Yes most industrial engines had a Magneto..

they are usually easy to start too...

with a rope around the fan pulley...

rather curious this engine
Dirk is probably right about it being an ex industrial engine
as aussie 40hp beetles never had the D engine numbers
that was a euro thing
also notice next to the blanked off heater hose holes in the breast plate it has the twin air cleaner preheat hose holes blocked off
thats also another non aussie thing
euro and US 67s only from memory unless its aftermarket tinware

1 thing for sure tho its a 40hp 1200 inlet manifold but opened up the engine could be anything
