Aceup Energy 4350W Portable Gas Generator for Home & Outdoor Use - 30A Outlet, CARB Compliant - Power Backup for Emergencies, Camping, RV & Job Sites

Thanks to Amazon's excellent delivery system, this generator arrived the afternoon of the day before its scheduled delivery date. That proved particularly convenient because it avoided a delivery during heavy rains. The generator arrived in excellent condition and was easy to prepare for operationBecause of weather conditions and conflicting personal priorities, I didn't attempt to operate the generator for several days. The generator did start, but it required many pulls of the starter cord (I lost count but estimate the number of pulls to have been over a dozen). The ambient temperature was in the mid-40s. It supported the modest loads that I applied very nicely. I am following the recommendations for a gentle break-in period, so there has been no attempt to operate the generator anywhere near full load yet.I have operated the generator several times to break it in, and each time, it has required many pulls of the starter cord before it would start. Because of previous experiences with other generators, I began to suspect that its spark plug was defective. After removing the original spark plug, I found that it was a "Torch" brand spark plug. I have had problems with all Torch brand spark plugs in the past with other generators (most of those spark plugs were so defective that the generator never started until the spark plug was replaced by a different one). I replaced the "Torch" spark plug with a new equivalent "Champion" spark plug, and the generator started with less than half as many pulls of the starter cord, and as a very pleasant surprise, the engine noise level was very distinctly reduced and the vibration of the engine was significantly reduced, too.Some useful information in the owner's manual is the clarification of the protective circuit breakers for the different outlets. The pair of 20 amp outlets are protected by a 20 amp circuit breaker, and the 30 amp RV outlet is protected by a 25 amp circuit breaker.
