Hi Cliff,
The fuel line set up looks much better.
You can make a brass collar for the black cracked carb body, slip it over the venturi's carb body wont allow the crack to expand.
I see you have a pressure line connected is the nipple on the carb body. Did you or has someone drilled through the aluminum crank case?
From the factory only the nipple is there with the option to drill thru all the way would require you take apart the engine prior to drilling.
The red carb body is the .051 RC version with the thick wall tab to support the RC muffler in your case the extra plastic will help avoid splits.
They always tend to split on the back side. I noticed the engine prop plate very unique wonder what the purpose of it is.
