Okay I think I cooked the engine tonight, it was running over 150 degress celcius.

To me it looks like the sleeve is discoloured (like when you heat a piece of steel it goes rainbow) but I can't tell

what do you guys think?

it's an OS TG so the liner isn't brass coloured to begin with.

to me the colour looks ok... what u need to check is the pinch of the p/s and is there any detonation on the piston surface!

Ashley Cobb

It still has pinch (a bit thristy though) and the top of the piston is dark brown in like one spot,

I pulled the wrist pin and conrod out and there is a spot of brown colour underneath where it is on the top of the piston.

What do ya think?

Also I can't be sure but the top of the piston doesn't look "flat" anymore

That would be cheating wouldn't it?

Ashley Cobb

Nah don't need to cheat, winning is not worth it if you cheat.

nope its not cheating, its just a way to get rid of the carbon build up. and also make it more fuel efficient

do they need to be more fuel efficient? I completed a 10 min final today, pitted at 5 mins and when i finshed, had half a tank left.

cleanup the piston and button head and check for any tiny holes...
if the surfaces are still smooth then everything still ok.

Well I gave the piston and head button a polish and it looks good.

Thanks for all the help guys

If you used anything other than tooth paste to polish it dude make sure you flush the parts very well or it will scrub when you next run it.
