leak test help

I want to thank you all again for all the help. I went over to the shop just now and went to retorque the head and cylinder and then on the last cylinder nut I found out that we never torqued the nut after putting the clutch cable back on. We had messed with the clutch cable and then didn't torque the nut that has the little bracket to hold the clutch cable. It was only on snug. I don't know if that was the trick but I pumped it up to 6.5 pounds and it held for over 5 minutes so I call that a success.

 
Nice save Nick !
Glad you got it figured out and it was a simple overlook that got caught before any damage was done.

But you should still listen to Larry and call your builder :)

Well I don't really have a reason to call him anymore. He called me when he finished with my motor and I asked my questions then. I also asked a few more when I received the motor and went to put it on. The only thing I didn't know is if he leak tests them before he sent them out but that doesn't matter anymore because I verified that it is air tight.
 
Thanks for not blowing up my phone Nick. So what did we learn here? Let me help. Once we send the engines out of the shop, the rest is up to you guys. I probably would have never figured this out over the phone and I would have wasted a sh*t load of time trying to help. The shop is packed (I mean really packed) with work and a problem like this is only going to slow everything down. Everyone waits until the last minute to send their jobs out and they expect to get them back the next day. That's an impossible task when I spend 5 hours on the phone every day. The lesson is........Take inventory of every step you take when you install your engine and do it right. I can build you a killer engine, but if you toss a filthy pipe back on it, don't jet correctly, use a junk air filter, or the wrong plug / fuel, you're going to have problems. If you leave an ice cream cone in the sun, it's going to melt. Is that the ice creams fault, the suns fault, or the person that left it in the suns fault? Glad it all worked out. Back to work for me.

Yes, lesson learned. I know how busy you are and that's why I didn't bother unless I had no other option. I'm still anxious to see what this motor has in store. I still haven't even burned thru my break-in tank because I'm trying to make sure everything is perfect so this nice motor doesn't blow and you've had my motor back to me for what has probably been 2 months now.

I fixed my air leak and have the suggested needle, slide, and a bunch of jets coming in the mail today so hopefully I can get the pilot/air screw and needle figured out during break in and then after I can figure out my main. I got it running rich right now until I can get it dialed in. A $2 fouled spark plug is cheaper than a rebuld.

You need to get that idle speed adjusted to specs with the first heat cycle!

Running rich is not necessarily the correct way to break in an engine!
