I have never sealed or used loctite on my nitro engines. I am not against sealing the engine, but I wouldn't do it unless I suspect there is a problem.

Default Ofna Picco .12 engine

I have had a couple of these engines. The first one I purchased in May of 2005. It ran fast but sensitive to needle settings. I discovered a leak in my fuel tank 3/4 full line in the seam. After the tank repair the engine was much better from idle quailty to full power. It failed with a broken connecting rod, (my fault, the flywheel nut looseded up (8/2005)).

I purchased another one in Sept. of 2006. This engine was like night and day difference from my original. It is much easier to tune and the carb appears to have been updated internally. The LSN needle settings are very different.

Default Air leaks

I did seal the carb and its tightening bolt on my old engine. I did this before I discovered my leaky fuel tank. As for my current engine, I have not found any air leaks, so I have not bothered with sealing it.

How do you check the engines for air leaks? I understand what you are doing, I'm asking for what tools do you have or purchase? What do you use to block the carb area and exhaust area?

Your finger. If the engine runs more than one second after you completely cover the intake with your finger then you have an air leak.

How are those Picco roar legal engines. I have one that I have not ran yet but I plan on using it next season. I got mine with out the exhaust sytem. Other than the smaller than usual header size it seems pretty decent when I broke it in.

Sounds like a plan!!!
My breakin was pretty easy once I got a few tanks of fuel through the engine.
The engine is more of a low torque power plant. I like the way it runs geared up. With the proper gearing, you can keep up with most cars on the track.
