-> tony_: and if the distributor is turned other way, you should connect the first cable to the hole where the thumb is pointing to (but it is the shortest cable, so it may be too short), or take out the distributor and put it back in the right rotation.
-> tony_: ignition order is 1-3-4-2. When you turn the engine, so 1st piston is at the top, thumb of the distributor should be about 2.5 o' clock. There should be plugged cable to the 1st candle.
-> tony_: I recomend type from Rapid.... (whole gearbox+axles). the best from this type is gearbox from 120LX or Rapid RiC, but due to manufactured pieces it is almost impossible to buy.
-> tony_: the set of pistons, tonques and rolls (i dont know how to translate "valec" :-)) costs about 2684CZK, chain+sprockets set costs about 500CZK, but there is a problem with quality of secondary manufactured parts... :-(
oil pump can be repaired - you need membrane and ventils, its no problem to buy - it costs about 100CZK
very big problem is transport of parts to Romaina - maybe some of members from this site can go near you - for example to holiday, its perfect chance to transport some of parts :) transporting by post may be quite expensive
