Gil,

10 mL of a zero-weight oil would be perfect dude.

Let me know once you’ve had time to do more tuning carburetor adjustments,
and how it runs after you’ve slightly leaned out the low-end needle…
I think you’ll immediately see and hear a difference in how your engine runs. 

I have also noticed the engine dissipates heat very quickly when using a fan close to the engine.
Anytime I run mine longer than a minute I turn my small shop fan on to keep air blowing towards the engine, and it immediately cools the engine while it’s running.
I’m going to use my temp gun this evening when I run it to get some temperature numbers.

I have been running my engine without the copper pipes, and I was checking to make sure the exhaust valve wasn’t getting too hot, which it wasn’t. I was surprised how cool the engine runs, which is a good thing.

Talk to you guys later, -j
