13,500btu a/c on a Yamaha 2400iSHC genny? Hard Start Kit?

My generator is a Yamaha EF2800i. It's about 10 years old, open frame type but otherwise very similar to the 2400 model. Same engine, etc.

It wouldn't run my Coleman Mach III A/C, unless economode was switched off. Even then, it was an iffy proposition. The SPP6E, along with a fan delay circuit, fixed things up excellently. And in my case, the hardstart cap was very easy to install. Literally plug and play.
