Greetings Paul -

Hopefully I will solve some of the mystery regarding 2002 distributors - and not open a big can of unruly worms. So Here goes:

The distributors offered from Bosch have 10 digit numbers stamped into the aluminum housings - but often have abbreviated numbers such as "ID48X" or similar numbers affixed on a small tag. There were both mechanical and vacuum advance units on the tii depending on year.

The early tii's (1971-1973) had mechanical advance units ending in Bosch number "008". The 008 distributors are no longer offered from Bosch. Instead they offer the part number ending in "002" for the mechanical 4 cylinder application. These seem to work well on carb. model 2002s (I have one on mine) but have a slightly different advance curve from the original "008" units. When required they will function reasonably well on tii's - but again - proper tiis should have the "008" units if at all possible.

002 distributors are readily available for $159.00 incl. cap and rotor from Bosch.

As for fuel requirements - I swear by higher octane - because it's cheap insurance and allows me a larger margin for error in ignition timing. I have been told time and time again, however that 89 octane is just fine for 2002s up to 8.5:1 or so- compression.

I suspect the likelyhood of good detergent additives is greater in the higher grades of fuel as well.

BTW - I have never had to replace valve seats to accomodate for the lack of lead in any US fuel.

Best Regards
