Generac 40G Hard Start

I went out this evening to check for clearance of the plastic cover and found it OK. But doing so, I found the choke to be traveling a very limited amount. Before I could figure out how to adjust it, the mosquitos ran me back into the house. I will try again tomorrow.
Thanks for the suggestion BTP01.

Again I was having the same problem that you are having although I have the QuietPac 6500G model the symptoms are the same. On page 57 of your manual it shows a choke solenoid plastic boot. That is the same part that was causing my problem as it was contacting the choke and not letting it move smoothly. I put a spacer (Washer) in between the plastic and the metal and it solved my problem. I hope that this might help you.

The Troubleshooting Chart in the Generac manual doesn't address the problem I'm having. Perhaps I should adjust the choke to apply more strongly.
Anyone else with a Generac 40G experiencing failure to start with remote? Spins, but no start without partially closing the throttle manually.

Possibly the choke is sticking. When you move the throttle locally you are probably unsticking the choke. I had that problem on my Generac. I repositioned a plastic cover over the choke solenoid and I no longer have the problem. JMO

You need a specific troubleshooting chart to follow which is a factory service manual. For a fact my opinion of Generac designers is that they consist of people that are overlooked at bed-count.
