This was a conversion I did a few years ago, that worked perfectly up to early this year. It is an aluminum adapter conversion on an AllPower APGG4000, with GX200 clone.
It used to start on second pull after a long prime, everytime. Then it became increasingly difficult to start, but eventually would. We had an extended outage this past March and I ran the genny for 3 days. I had to do an oil change and the unit just would not start after I was done. I had suspected valve lash, so I did an adjustment (many adjustments) and it finally seemed back to normal. After not testing for a few months and now that it is cold, I am having difficulty. It is hard to start and run on NG, but not gasoline. If I adjust the A/F from load block, I can get it going, but it is unstable. After shutdown, I am back to the hard to start condition. I have to re-adjust the load block bolt. I also noticed that the two vents on the sides no longer cut off gas flow when I plug them with my fingers. This used to be the case. I also always had to start with choke open and run open. I also noticed that the engine did not change speed with choke open or closed. The gas supply I am using is for a gas powered pool heater. Very oversized for this application and worked flawlessly up to early this year, I am starting to think that the KN regulator is not working properly. Your input is appreciated.
