I bought a few of these over the winter. E-clutch, soft start, and 'smart switch'.

All 3 run fine in the shop on mains power, but only flutter on the 305g efi. Plugs read 125vac on high idle, but can't read the frequency. All of my other equipment runs fine on it.

Can anyone else verify this, or have a workaround? The documentation doesn't mention this, not can I find anything using Google.

Thanks
