Dar. Thanks for your replies.

I will get some Castrol-M and add to the mix. No reason to take chances or experiment with a twin engine setup. I plan to run with onboard glow for easy starting and for better low speed reliability.

By the way I just took one of the engines apart. Look really nice for the money. The casing finish is a bit rough compared to my OS an Thunder Tiger engines but who cares as long as they work well. The casing on the inside has some small holes in it but that wont matter with the piston sleeve inserted. The sleeve look real nice and the chrome plating look thick. Also the engines look awsome with the blue heads. Again for the money these babies cost I think they are pretty well built and from what I hear they run well too. I look forward to break them in next weekend.

One recommendation. One should disassemble the engine and clean them well with fuel or similar. I found several metal particles in both of mine. I do this with all my new engines and only on my Saito did I find nothing. After cleaning the engines I lubed them well before assembling. As lube I used sewing machine oil (acid free).

RCer.
