Carburetor Retrofit for Generac 073112B

I've had major issues with my Generac NP-66G in my '96 Damon Intruder for about two years now. The power sagging even with no load on the generator and the transfer switch eventually jumping back to shore power due to low voltage. Since I've had to zip tie the choke shut to get the engine to stop surging, figured that had to be the problem since I'd eliminated all other possibilities...duh. I didn't bother to modify the choke on the new carb to make it work since I live in Southern California and I rarely go dry camping when its freezing cold 'cause my coach is insulated like a tin can. Plus, my choke linkage is so bent from me taking the original carb on and off of the engine about 5 TIMES in attempts to clean it, the choke solenoid won't pull it shut. The generator runs flawlessly now. Had I read the part where you have to hook up that solenoid on the float bowl to the fuel pump circuit, it would have saved me about 30 minutes of head scratching and swearing before I figured it out on my own finally using some common sense. The generator runs like it so fire now. I don't think it's ever ran that well in the 17 years I've owned that coach when I bought it off my Dad. Throttle response is awesome. The power barely dips when my a/c's come. Both a/c's running, microwave, fridge on AC, the battery charger, every single light in the coach on; so problem. Totally worth the money.
