Model Forum / Radio Controlled / Land Models / May 2005Megatech M16 won't run
Hello all, I have two Megatech M16 motors (.16, 1HP) that will not start. I have both of them bench-mounted and have tried every thing I can think of. I know the fuel and glow plug are good. Fuel is moving thru the engine (and out the exhaust) and I've tried every conceivable needle setting to get it to at least pop. I can't even get a single pop out of them. I'm using a cordless drill to turn the starter bolt and can get them up to 200 RPM or so. Backplates are snug, carbs are snug, no compression leaks from what I can tell. There is no conceivable reason the motors should not start! HELP!

A brand spankin new one, no I haven't. But I've tried two others I had laying around, both of which will start and run my other motor on 3 pulls or so. I'm gunna call Megatech and see if they have an engine exchange program, so I can unload the M16 and get a Q1.6 or M21. Doc Flooded?..Remove the glowplug and turn over and get out excess fuel ...replace the plug and try again....... (make sure plug is good as well as ignitor)... > Hello all, > [quoted text clipped - 14 lines] > > Doc "Doc" wrote: > Hello all, > [quoted text clipped - 14 lines] > > Doc Do you have a pipe attached to them? I'm not sure they will run well without a pipe. Just a thought.

Just a thought. Is your glow starter good? SignatureJim ----- www.onandaga.com >> "Doc" wrote: >>> Hello all, [quoted text clipped - 21 lines] > > Is your glow starter good? Ripped em' apart yesterday; pistons are chewed all to hell. Dunno how that happened; used Trinity 20/12 and 20/18, fuel filter, new air filter and broke in properly. Didn't overheat AFAIK. Doc Compression ?? % fuel?? Get a new plug and fresh fuel. Patrick > Hello all, > [quoted text clipped - 14 lines] > > Doc Tear the motors down! here the piston has a port for the exhuast has to be filed and or sanded.If your glow plug is all crudded up,then your piston casting has been flawed in its manufacture.Clean up the flaws! |
