Hello everyone in nitro land, question: After going through 2 nitro engines without success(some unknown .21 Picco 5 port, broke the con rod, beat up the button and piston head, to which no one knows its replacement parts, then an OS VSpec which I completely rebuilt with an actual Lamberto Collari rear bearing, Dynamite front bearing, new con rod, pinch, carb gaskets, back plate gaskets and head shims, which won't tune properly, darn 3 needle carbs) I then bought an L-Collari Innotech XS 390 for my OFFROAD 1/8th buggy off a friend. Now, according to their site, http://www.lcollari-innotech.com/XS390.en.htm
, there is very little difference between the on road and offroad engines with the exception of the RPM's. Does anyone know if there is any real difference between them? Am I nuts having it in my buggy? I'm still figuring out the three needle carb, and would rather a 'dumbed down' 2 needle Novarossi 21 plus 5, but this is what I have to work with. I'm also using a JP1 pipe.
I also put a small crack in the head, who makes aftermarket, larger heads? Is this a Novarossi based engine or Sirio or? Mine has 6 head screws, not 4.
Any advice is welcome, I'm at the end of my budget and frustration.
Thanks in advance,
