Would not crank at 1st. I checked spark plug & it was fine (must use included spark plug tool) then I opened the dran screw on bottom of carb to let fuel flow. After all the air bubbles came out it crank fine & has done fine since. Runs my camper just fine.
I purchased the igen 4500 inverter a year ago for my travel trailer. We have camped primitive with it over 20 times without any trouble. The larger capacity fuel tank allows it to run through the night without having to refuel, and has enough power to run the whole camper including the microwave.
This unit is a warranty replacement for one I bought in July 2021. Out of the box, the autochoke did not work. fortunately I found a video on YT that showed me how to fix it in about 10 minutes. Unit ran well and met my power needs for my 5th wheel trailer. Unfortunately, the inverter failed after about 125 hours. Warranty service is a hassle. WH's tech support line is not supportive. Finally took my unit to an Authorized Service Center and it took them several weeks to get a replacement authorized. After that WH shipped the replacement in a few days. Unfortunately the autochoke doesn't work on the replacement and the YT video doesn't seem to apply. Back to the tech support grind!
