Used condition, compression feels low when spinning crank by flywheel. Includes STS 0403 pipe. Please inspect photos closely and reach out if you have any questions. We take every measure to carefully inspect each engine and report its true condition/identify it properly in good faith. Unless stated otherwise, these are used engines and it is possible that deeper inspection/disassembly may reveal small defects not noted. Due to the subtleties in engine differences, it's possible that occasionally we misidentify the engine. Please factor these terms in your bidding and contact us if it looks like we missed something. FYI- WE BUY RC CARS! Based in Southern California, but will travel anywhere in the United States for the right deal/enough cars. Cash ready - reach out if you're ready to sell.
