When you got the engine, was it plug and play or did you have to mess with the wires ?The best description I can give is that when cold, I can go fast and climb a hill and the engine does not feel it, but after a minute,going forward from a stop will kill it and engaging the blades also.
Sorry for the long winded post and thanks in advance for reading it.
You did plug the wires back on to the voltage regulator ?
How old is the battery ?
At the battery terminals, do you have 13.6 volts ?
With the engine running at WOT, are you getting 14 + volts ?
The chances of 2 coils going out at the same time are like my chances of winning the Mega Million......
Unless one was already dead, then the other dying.....
Let us know how that works out......
Fuel valve fully open ?
If you are running saddle tanks, there could be trash partially blocking the pickup/valve at the bottom of the tank. The same goes for the valve to switch tanks if you have one.
