Status: offline 		I am new to this hobby. Well, i jumped right in after reading a few articles and took the engine out of my Exceed Hyperspeed car. It is a .16 engine and i ported the sleeve on it but going back together im unsure on which way to face the piston as there is a hole cut in it on one side. It can either face the exhaust port or one of the intake ports. Also what would be a good starting point for the low and high speed adjustments on the carb? Thanks

Status: offline 		Thanks. Ive got it running fairly well and i posted something in another thread but havent gotten any response. Is it possible to do some modifying of the stock exhaust on this engine? porting the stock exhaust manifold, and port matching the sleeve to the cylinder at the exhaust port, etc...?

Save the porting for those (Modders) who know what they are doing. If you can't reassemble an engine correctly, I doubt your ready for self done engine mods.

With all due respect i asked for advice and not criticism. At $50 for a new engine of this particular model i dont think ive got much to worry about. And i just didnt notice which way the piston came out of the sleeve its not like i put the piston in upside down... I own a motorcycle shop and i think if i have the skills to completely rebuild a Harley or sportbike engine then a little nitro engine should be in my skill level... Just asked for advice is all
