SORRY I'M not to good at posting pics yet. this is a itailan motor i don't know if thunder tiger is a itialan company. it is side exausti it has one boost port and two fuel ports and the exaust port. it is a old wore out motor but the guy just gave it to me and said here you can have it show me what kind if work you can do. i told him i do car motors but have never done a plane motor. he just wanted to see how steady of a hand i have. he has some customers that want some mod work done to their car motors. but i would like to mod this and make it run again to see how the mods work, he sells alot of planes out of his hobby shop. thanks for the info in advance.
