Hello

I just finished the break in on the .75 and when I try to kill the motor by closing throtal it will run on for a while at a very low idle. I fully seated carb and have a good seal on o-ring. I also checked back plate where o-ring seals it, it looked liked as if the o-ring wasn't sealing good so I put some RTV sealant to make sure.

I still have the run on so where else might air be coming in ? The engine seems to run well other wise. I have two .46's and a .61 that don't have this problem.

Thanks
Frank
