I'm new to thread and I am looking for some insight ! I just acquired 2 novarossi engines.
1st up is a used 21-5kt, guy claims to have only broken it in with a gallon and half ! I can't turn it over with my hand so the compression is realy tight ! I took off the turbo head to clean it out and I noticed there is NO shims in it ! Downloaded the Manuel and it shows there should 3 shims ! Anyone no for sure ?

2nd is new in the box 2001bf never seen fuel ! Anyone have experience with these ?

Any feedback appreciated !
