Hello All,
A few questions about the GP460 engine if I may...
How is it in terms of reliability? (site search did not really give anything)
How loud is it idling and while under load? (maybe compared to a Honda or EHO35)
As always, thank you for the information!
I would not rate this engine well in terms of reliability, so far. There's not much meat near the bellhousing bolt holes. I cracked the housing from overtightening. On one engine, the bellhousing threads pulled thru, and I was only using the ratchet with one hand. Also burned a piston at high speed, which could've been my fault.
Loudness is subjective. My friend Rick's 460 is VERY quiet, using a Happy Time stock muffler. I had a new 460 with stock muffler; Rick's engine was quieter than mine. It depends which exhaust you use. With a Dominator pipe, it's very loud. With an ADA S1 pipe, it's quieter than a stock muffler. With my present SBP Happy Time expansion pipe, it's even quieter.
Under load, it's louder, but not SUPER loud like a Tanaka 47R. That sucker's got a LOUD exhaust at high rpm! With the 460, high speed engine noise is bearable, especially with a shift kit. Engine noise lessens as you shift to a higher gear.
Hope this helps. This engine is noisier than your Honda or Subaru, but it's also 2.625 times as powerful, 1.6hp as compared to 4.2hp!
Hope this helps.
