I purchased this flywheel for an ultralight power plant. Weighs in at 4.5 lbs . Stock flywheel on my Duromax 18hp engine is 12 lbs. A 7.5 lb weight reduction. Bolted right up and started right up with stock coil. Seems to idle fine. Fins are 2/3 height of stock and only 1/2 as many so I may get some small power increase. Very pleased so far.
