Reïnstall all the bearings, I had it with a R&B engine where the frontbearing was not seated well.

Not sure about the 353. but I measured my 3SCT tuned and with no shims; it has a real head clearance of a .30mm so for 20% i would add .15mm shim. the engine comes with a .30mm shim. I install this for 25% which gives me a total head clearance of .60mm. A little fat for 25% but better to be safe.
Adding .40mm of shims would get around .70mm head clearance this is a little too much for 20% your low end will suffer.

I can only speak for the 3sct tuned version. But my gut says they would be the same. I don't think they would change the stroke between these two engines. Maybe timing not stroke. Again I'm really not sure.

Usually the black steel ones that come with most Nova motors work perfect.
Another option is to find a NTC3 clutch bolt and shim kit. It comes with a few tiny little shims that fit over the bolt between the end of the crank and the holder/retainer whatever that thing is called (the piece the thrust bearing rides on). That can give you the few tenths of a mm you need.

Hi, I was wondering if anyone could give me the factory settings, including mid speed needle, for the MR12 with turbo head? Any help would be appreciated!

The mid needle should be flush with the carb body. Don't recall the others.

I had the same issue.
I shaved .5mm of the the collet by sanding it on emery cloth making sure it was taken off like it was machined off.
It did the job, I just get .3mm endplay, with .4mm fly wheel to crank case clearance.
I have a GRP .21 and only have .4mm of clearance with standard GRP collet.
Not sure why I was the only one with the problem because I can install clutches blindfolded.

Why is there like 2 holes on the sides of the crankcases of Nova .21 engines.
When attaching the header do you wrap one large spring all the way around and 2 smaller ones on either side because I only got one large spring with my header.
Im new to Nova .21 engines as I have always run Ninjas and GRPs
Thanks

Yep I three spring them. One long one and two short ones.
