Hi All,
I have had the car about 10 days and would really like some advice as requested below.
The car has a 807-01 R16TS motor from an Australian delivered Car.
I ordered a nice alloy rocker cover from Banks Europa, to find out the hard way that Australian delivered cars came with a Bosch Distributor not a French Ducellier.
The Bosch Unit is considerable larger in diameter to the Ducellier and will not fit in the recess of the cast alloy rocker cover.
If anyone can tell me the correct model Ducellier for a crossflow motor I would appreciate it, as the car has Webers a mechanical unit would be preferable if such a unit exists, any advice on where I may obtain a rebuilt unit at a reasonable price would also be appreciated.
As would any information on ignition timing, R16TS has 18 Distributor Degrees (36 Crankshaft) at 2500 rpm, Lotus s2 Manual has
18 Deg at the Distributor (36 crankshaft) at 3000 rpm for the Renault wedge motor. (other than that I could not find much on the internet, perhaps I am looking in the wrong place)
My car has a slightly non standard Australian Waggett 127 Cam, if it matters,
Lift 0.265”
Inlet Opens 23BTDC (standard is 21)
Inlet Closes 55 ABDC (standard is 59)
Exhaust Opens 53 BBDC (standard is 59)
Exhaust closes22 ATDC (standard is 21)
The car has twin 45 side draft Webers a quick look inside reveals 48f idle, f11 emulsion, 180 mains, nothing else marked, have not had the venturis out.
Gave the carbs a clean, set floats, balanced (with a sync) and set idle. Very rich at idle, with mixture screws as lean as reasonably possible, seems fine when it come off the idle circuit.
Also found some water in the carb bowls, traced this back to a damaged neck on the fuel tank where the fuel cap seats, water could get in from a simple wash, so I will have to order a new tank neck.
Tuned it best I could with little information the old way by ear followed by, tune, drive, pull over-adjust, and do it all again.
I ran a spanner (wrench) over every inch of the car for a few days and did anything required. Then ran it up a local small mountain (1500 ft) that is set up with good tarmac for hill climbing, best I have done after 6 years of practice on my heaver cruiser motorcycle is 70 kph, I hit 140 in a short burst in the lotus, it was/is amazing, lower centre of gravity and 4 paws on the tarmac, truly amazing stuff.
Bought some nice personalised plates (vanity plates in the US) TYP.54
Any help on advice required above would be appreciated.
