Default if you don't mind, help me seal my engine.

I bought lucky 7. and my engine is fully broken in. I broke it down and inspected it and cleaned it. Now i am going to reassemble. I know to seal it at the carb neck, back plate, and fuel nipple. Question is, do i put it on the neck, plate, nipple then insert it? Or put a bead around it after i insert it?


Oh, i have a small crack on my carb neck Cant really feel it. and the motor has not expierienced a air leak, it is still perfectly round. I only put it finger tight like i am supposed to do and gave it less than a half turn more like the directions said

how bad does that sound? do i need another carb body? It runs great and i have not even sealed it yet. damn just DAMN! That thing is fricken touchy.

well, the directions said i don't have to disassemble the motor. So my internals were all laying out, so i went ahead and put it back together. It will still work if i seal it on the outside right?

anything to say on the crack? anybody have that happen to them before?

It depends who you ask.
Some say put it on the O-ring and then assemble your motor.

Some say to leave your motor assembled and just put it into the cracks.

JPalessi seals motors the second way, and I trust what that guy says.

I would re do it.

I would zip tie the carb boot if it starts running weird all of a sudden.

re did it. Why would it start running weird? And why not zip tie the boot now? Is it bad for it?

dreaux dreaux dreaux......

If there is a leak, you need to fix it. No if's and's or but's. If you dont, you will have an air leak. I would need to see a picture, but I would seal it up with RTV sealent if the part of the body doesnt come in contact with nitro fuel because rtv is not nitroproff.

If the motor runs good and then you can't get a tune on it, then you have developed an air leak. With O.S. the carb boots leak. I just like to do it until necessary to be able to give feedback on how a motor will do right out of the box.

I ran a O.S. .30 and never cracked the thermal insulator, and I tightened the heck out of that sucker. Remember your tightening a little screw on a toy not the lugs on your car.
