My friends losi rtr .27 engine, we wondered why it wouldnt run well, sending it out for a sleeve resizing lol

Yea I would say its getting close to needing a pinch. It wouldn't hurt to go ahead and do it now. lol

Not getting close. That definitely needs a pinch... The piston shouldn't come up through the sleeve.

Who'd you send it to?

getting close ,,,, i would say way past due thats me

since rcrenew dosent work on these size sleeves im sending it to rayaracing

i dont even know how this thing honestly ran after seeing this, never seen a p/s get this bad

i can tell you just from looking at it, that it has been run incredibly lean

Definitively need a pinch... or a new piston and sleeve

that actually looks GREAT...no joke...yeah it needs a pinch but it still looks like a great piston and sleeve(from what i can see lol) pinch it and run it:batman:

well actually it does look alittle LEAN :lol::lol::lol:PINCH IT AND RUN IT

WOW yeah time for www.rayaracing.com they are the best out there

I have never seen a P/S like that hahahahahahhah

please, this is not my p/s, but out of a friends losi rtr .27 mach engine. its near 3 years old now. i sent my v-spec p/s to rayaracing along with this, i hope he can get the .27 back into spec. it would actually run for about a tank pretty well.

today we were at the track and i clocked it at 240 degrees but it still showed a nice smoke cloud, i richened it up a bit and it would bog so bad lol. after the one tank he tried to go for another but couldnt get it re-started, so i looked at it and i was like wtf is the glow plug out? the motor had what felt like no compression, to which i then learned that it actually didnt, so i took it apart and sent it to ray, we'll see lol

Id say you dont know what your looking at. The only thing wrong with that piston and sleeve is it needs a repinch. If he hasnt cleaned the top of that piston, and thats the way it came out, is the reason that motor has run as long as it has. Arent you the one that has gone through a ton of motors and always had problems tuning them??????? Maybe if you knew what you were looking at youd have better luck......

piston looks fine to me. If your assuming its lean because there is no carbon on the piston, well, that just means he is running good fuel and not running the motor slobbering rich...

nope, have not cleaned anything, first time the p/s was ever taken out of the motor
