For those who own Ventus Cm: have you ever measured the voltage on the starter when it is running?. Mine, with fully charged battery, while electric starter is running, voltage on battery fall out to 10volts, and on starter I measured only 6 or 6.5 volts. I have a voltage lost of aprox 2 volts over the positive wire and 1.5 over the negative one. Is that normal? I have starting troubles sometimes and i think it is because of it. What ...

Next to do, I will measure the current with a DC Amperimeter in order to check if starter is consuming more tan normal.. It is labeled 400W, so it should consume no more than 35 Amp. And I will try to get borrowed another battery to compare.

One thing to make clear: once the engine starts it runs perfectly with any problem. Never stopped itself. No carburation problems.

But i am thinking now:… Could the engine be hard? Heavy? Even if i decompress it to start spinning

What is gauge of the wires from the battery to the starter? I'd suggest at least 8
gauge if the starter draw is 50 amps; 6 gauge if it's 100 amps.
