I had him mod it and put ceramic rear bearing in it. UPS man brought it last Friday.
I’m not sure what effect the different venturis have yet I always just ran what came with the engine. I need to ask Rick about that.
I also made a pre heater for the cylinder head that is 12 VDC it heats the head from 60’F to 200’F in 15 min. It draws 3.5 Amps by my meter so I am powering it from my bump box witch has a 12v 7ah battery in it. Should help me with cold starts while I’m breaking engine in. It’s still a little cold here in pa.
Engine SN# US0000096
The GX-7R with 2072 is killer in stock form, so your modded one will awesome.
Smaller venturi's will give better run time, and can actually increase bottom end performance very slightly because of the "ram air" effect they can create (so I'm led to believe).
