Problem with serpent engine monoblocks

Hi, i have a Serpent 960 and the LCG chassis+monoblock set.
The problem is that the pinions can't be perfectly aligned with the spur gears (they are too far back). The first gear spur is about 1mm further out than the pinions and i can't position the engine further out.

When browsing the serpent forums i noticed there are 2 monoblocks, the picco/mega one (#903194) and a general one (#903201). Apparently the LCG set comes with the Picco one. Is this the problem ? Or is it supposed to be this way (weird) ?

I can't be the only one with this problem... i think

Just remembered, i tried with the engine blocks that came with the car and the problem is the same, so maybe its supposed to work that way. Or the problem is the chassis ?

I have a 960 also and have had this problem since day one. I have both Sirio and Nova Rossi and they both won't line up no matter what I do. I have tried filing the engine mount holes in the chassis as well as the engine mounts(both stock and monoblock) and neither have resolved this problem. Really disappointed with Serpent on a few things with this car.

Hmm, but aren't "Screws engine mount + flange (4) (#1017)" the same as the screws that come with the monoblock "Mono block M21 LCG (#903194)" (just a different color) ?

If yes, then i'm already using those screws.

Mine match up well with the LCG Chassis and Novarossi motor. It can also be in the clutch build. If I remember correctly, the new directions omit the 0.5mm washer behind the flywheel/crank brass engine cone. The question I would ask is how many spacers do you use between the thrust bearing and end cap (technical term) :-) If it's quite a few, then how close would it line up if you didn't need so many? That shim between the motor bearing and cone before the flywheel helps take the additional spacers out between thrust bearing and "end cap"... Which may help you line up your pinion and spur.

Actually i thought it might be a problem with my clutch too. I'll redo it and then post back the results.

Hmm, apparently it can be pretty much fixed by putting a 0.5mm shim before the cone. Unfortunately i have a broken thrust bearing so the real test will have to wait till i replace it.
