Nitroholic , what I know about nitro engines isn't worth knowing.I know bugger all but the basics.Never liked them and don't want them.I was just going to get this thing going so to sell.I was looking at some bloke re-grooving the piston and another bloke pinching the cylinder. That might be an option to go for. I also read to never buy a used engine as they are normally knackered thats why people sell them.
