I dont remember who I got mine from off Ebay.
I got it when everyone was buying them.
I got it as a spare and is on the shelf so cant say how it works.
Think someone had an issue with the accel pump.
I think the choke caps if it comes with electric one might be 12 volts and not the 6 or 7 volts used with the hot air asst.
They say to swap on your old one and run the tubes for the hot air.
Think of this as a bump good luck
