Hello im new to gas boats and want to modify mine. I have a venom segad 58 with clutch stock motor with venom head and exhaust cooling upgrades and venom upgraded intake. I was thinking about moding the stock motor but im not sure if zenoha parts will work in it i have only herd and speculated that it is a clone engine. If it is a clone would it be worth moding. The other engines i have considered using were the zenoha 260, or 290. I would try and mod either the stock motor or a new motor with a walbro 1069 carb, lightened piston, 2mm strocker crank, a moded head from gizmomotors, and there torquemaster pipe on a stock header. But my big question is that i have herd about people saying they advanced timing on the intake and exhaust but i dont know what they are talking about how do you advance or adjust the timing and what kind of mod can you do besides a iridium plug for the spark side of the equation and how do you adjust that. I know this is alot but i am the only one i know of in my town that has aything like this so am on my own for everything i do so all help is greatly appreciated.
