Hello everyone.
First of all it’s a pleasure to see how many people still care about this beautiful cars.
Here’s the problem. I’ve got a R4 TL 1990 with a C1C engine (956 cm3) and a Zenith 28 IF carburator and together with a heavy gas smell coming from the cockpit fan when the engine is not warm yet and a general issue of considerable fuel consumption (only 50-60 kilometres with 4 liters out of town at 80 km/h), if I lightly touch the gas pedal when the engine is warm and the second or the third gear in the motor badly shakes (I can ear a pesky thump). All its anchorage points seems ok. I thought it was due to the carburator and I tried to adjust the screw for the mixture setting as Clementine suggested, but nothing happened. Only if I screw it more (3/4 of turn starting from the all in position) the smell of fuel seems to recede, but not the engine problem (even if it reveals later).
I’m tempted to screw the mixture setting in a little more but I don’t want to make a mess. Any suggestion?
BTW The oil consumption is regular.
Sorry for my poor english!
