Good luck with your saito mikecam

I've seen bubbles coming back up the fuel line from the refuelling valve occasionally,once again not always,while the engine is running and thought the same.I bypassed it and the fuel filter too..same problem.It's the angle on the photo,the main needle is about 5mm away from the bolt head.The engine feels and sounds tight and sweet.Fuel cap problem?

Hobbsy i'd like to see your prop figures for a 62a.I'm running 10% nitro and all synthetic oil.Top rpm i can get with the 13x6 apc is 8500.

rlmcnii i think a soft mount is mandatory when you tune an engine like i do..
