what is the actual head clearance of RB R3?
I measured the head clearance with the stock silver .3mm shim on, using the solder trick and I found it to be .5mm !!!!
I am running the engine with 16% nitro fuel.
Isnt ,5mm head clearance high for 16% nitro or have I messed up somewhere on my measurement?
