Bore size for wing tube

[Lem and Christina Stevens]

Hey Fellas,

I have a Temptation kit that has foam cores bored for an aluminum tube with fairly thick socket.  I had planned to use a carbon fiber wing tube and the VERY thin socket.  However, the carbon wing tube socket is very loose in the foam cores.

Anybody already solved this problem with changing over to carbon wing tube with the thin socket?

   Matt I ran the Webra last year and it didn't work to my satisfaction until I added the MC carb. The engines are real stump pullers once you get the bugs worked out. Mike

    Thanks for the advice. The idea about using a perry pump is very appealing. I have been running this pump on an OS 1.60 in my Focus for about 30 gallons of fuel and it has been very reliable. This might be something I should try before changing motors, its a ton of work change to a different powerplant!

    Another good method we have used here in hot and muggy FLA is to do as Jim sez with tapping the backplate of the 145, but running the separate Perry P30 pump and stock webra 145 TN carb. Really works well since the pump is out in the breeze and gets plenty of cooling keeping it from cavitating. 

    The stock webra pump is suspect and has ruined many a practice session or contest for many guys, me included. In my experience the engine itself is excellent with outstanding handling characteristics, as long as fuel delivery to the carb is done correctly. FWIW

    Gordon, BTW, the Mintor has more problems than just fuel delivery, You might want to use caution.  I recommend you get the 140RX. replace the bearing with the stainless steel before you even run it and then enjoy a couple years of trouble free service. Many guys run this set-up with excellent results

      I bought a regular backplate for my Webra 145,tapped for a pressure fitting, and installed a cline regulater and a check valve which comes with the cline regulater. You now will have the tank pressurized similar to a YS system.This setup broadens the needle adjustments and makes the webra run well.
      Just make sure you mount the regulater as close to the carburater as possible,like 3 inches. I used this setup last summer.I also had problems with the finnicky pump and this is the only way I could make this excellant engine to run reliable.
      You spend 70+ more and have a good setup.
