Air leak beneath Heat Sink?

[duratraxrc]

I have had a very hard time lately getting my duratrax nitro evader bx dtx 18. to start and I noticed that I have lost compression and I figured it was the piston and the sleeve but just a second again I realized there was bubbles coming from underneath the heat sink everytime the piston reached the top of the sleeve, like that gasket underneath there is bad, is it possible that if that metal gasket is bad that it will cause bad compression and cause my rc not to start or......to start but everytime I let off the gas completely the car stalls.....the flywheel is easy to spin is why I am saying it may be compression

Check the fasteners holding on the heat sink. They may have loosened up. If they did that could cause loss of compression.

Yeah, I took it back off and cleaned everything in the area and checked that gasket and it looked fine, then I put it back on and tightened it down good and snug and it doesn't leak anymore. Hopefully that fixed my problem why it wouldn't start yesterday really easy...it would shut off as soon as I let off the throttle.

and then when I gave it a lot of gas it sounded like it was getting flooded because it had that deep tone and it didn't have any power, like it was bogging...or it had a strain on the engine
