I purchased a PepBoys PowerPro 3500 today for $300+tax after reading many post's.
The generator was in excellent condition without scratches or missing parts. All screws and bolts were snug. The manual was well written and informative.
I have no need for 240v so I removed the generator cover and found the two red wires many post's spoke of. I removed them from their post and connected the red wire comming from the pannel harness to the post holding the blue wires. I took the remaining red wire comming from inside the generator and connected this wire to the post holding the brown wires. The modification to full power at 120v on both panel receptacles was now accomplished. Total time for modification after cover removal, two minutes. The PowerPro 3500 is now wired for 120v 25amps at both recepticals as per the instructions from the Professor.
The motor was filled with 10/30 Mobil One, and the gas tank filled.
The engine fired on the first pull. I immediately noticed the unit was relatively quiet for a generator, and exhaust noise was exceptionally low. The remaining noise came from the moving mechanical parts.
I ran the new engine for 10 minutes, then I applied a 1500w load to the 120v outlet through a ceramic heator. 1500w load did not effect the PowerPro at all. I broke the engine in for about 1 hour at 50% load, then I connected an additional heator with selectable 750w / 1500w. The wattage was increased to 2250w without incident. I ran the gen for 30 minutes, then the load was increased to 3000w. I could now hear the engine taking the load as the noise level increased slightly. I only held this level for a few minutes before backing down the gen to 1500w. This is about where the unit will spend most of it's time, so I took a frequency measurement. The unit was operating at 62HZ so the engine spead was reduced till 60HZ was achieved. Here are the results at both the 120v 20amp standard receptacle, and the 120v 30amp twist lock. All results are aproximate but very close. (Both receptacles were thoroughly tested.)
No load- 123.2v, 62.0HZ
750w load, 122v, 60.7HZ
1500w load, 117.7v, 60.2HZ
2250w load, 117.2v, 59.6HZ
3000w load, 113.8v, 58.3HZ
Impression; This unit is a compact mature design, or an exceptionally nice clone. For $300 the PowePro 3500 is hard to beat. The engine never smoked or misbehaved in any way for the few hours it ran. At shutdown the oil level was still full and clean, and no leaks were visable. Overall I was exceptionally pleased with the performance and design of this unit. You can only get so much for $300, and for this price the PowerPro 3500 is a steal.
I hope you find my reaseach helpfull.
