Why the urge to have a pinch if you do not know if the engine really need it? So far known more engines have thee same low pinch so it seems well choosen.

A lot of .15/.18 RTR engines also have no or less pinch and do run fine. The cold situation does not tell a thing about how it is on operating temperature.

these are Go based engines with a cast piston...they need to be tight to function correctly.......or at least to function correctly for any length of time, I would send them to be pinched.....loose engines are no good !

OK the CHAMP has calmed down now. :-)
I appoligize for my earlier statement as I am not usually a hot head. Words can sometimes be mis interpreted on the internet, just like texting. So Wombat, I appoligize to you bro.
I really didnt mean to start a debate whether an engine should be pinched or not. Just simply stating my findings and my plans for this mill as no one got theirs at the time and wanted to let everyone know. Take it with a grain of salt and do what you all want with it. Its a 60 dollar engine, what more can we expect?
Some may want to run it as their primary engine, some may want to experiment with cutting, and some just curious.......it really doesnt matter as its a decent engine at unheard of pricing.
Anyway, would like to hear from others who got theirs in.
PEACE

i dont have mine yet but after reading your post im sending it in for a pinch not sure who to send it to though but i think it at least needs to be tight to start out with and who knows maybe i'll get 6-7 gallons out of it even 2 would be awesome for the price. course after a pinch i doubt the bearings are going to last. but lol

Hopefully you don't get the short stroke P/S/R in the photo that wouldn't work.

Wow, you got lucky Honu. Seems like it'll be hit or miss on this one.
Thanks for posting your findings. Now let her eat!

Thanks Shannon, I have some more Alturn on the way. I am also looking at getting a similar motor to this long stroke motor. Mine I will be ordering them with Dlc crank, Skf bearings and the 3 needle carb. Modded it could be under $150.00!

Got mine Saturday. Free spun the crank with just my fingers and no flywheel even after put a brand new p4 plug in it.

Opened her up right away, and decided to fill the crank with RTV 118 self leveling silicone.

Let her cure for a couple of days. In the meantime, I played around and stuck in a DLC coated Ninja crank. Spun smoothly, but did not start it. Chickened out.

Re-assembled the whole thing this afternoon. Heated the head to 180 degrees using my 110v competition heat warmer. Primed the motor and bumped it on the box. Figured the 4S lipo would either start it or blow it up.

Fired right up, heat cycled it for 2 full tanks, pulled heater off when temp approached 250 degrees and put it back on (unplugged) when it got to 205. I ran a 3rd at no more than 1/2 throttle. Good smoke and great idle.

Removed the engine for a disassemble to check the crank fill, and found that the engine now had much more resistance than before, but could not really feel a mechanical pinch. Figured my silicone may have failed.

Removed glow plug, and felt a tiny bit of mechanical. Disassembled the engine, and found all was good on the crank fill.

Lucky 7ed the HS needle, the carb body, and rear backplate. Re-Installed the glow plug, and clutch assembly.

Tried to turn the fly wheel and actually felt compression. To that I say- whaaatttt? Could this thing have actually expanded? Hmmmm.... I need help with this one. I have to say I would have had to experience it myself to actually believe it, as it is completely opposite to anything I've ever felt during a break in.

Removed clutch, and could not turn it over by hand with glow plug installed, even though I was able to do it easily before I started it the first time.

I would say that I'm still not sold that this engine can accept any abuse, or wouldn't do better with a tight pinch to begin with, but I can tell that the con-rod must still be virgin, and I won't spend any more time babying the thing. Race tune and some hot laps at the track are my next steps.

For me, it's fun to tinker, but I will always go with name brand when it comes to racing. I have too much invested in my stuff to leave it up to an unproven engine.

Hopes this helps anyone who was wondering what these engines are doing out of the box. If nothing else, they would be good for anyone looking to keep their RTRs going for a few more tanks until they meet the curb or pole of death.
