I just picked up a HF 9000 watt generator with the 13hp/420cc predator motor..
After some research I noticed a couple people mentioning the 420cc motor run on the lean side and have a tendency to not last very long with the lean condition.. Is there any truth to this and should a jet kit picked up ???Also is there anything I should look or keep aware of that may cause a problem ??? Oh I almost forgot the unit came with a cracked spark which was a Torch F7TC but the manual recommends the Torch F6TC plug.. So what is the right spark plug and does it matter if it comes with resistor too ???


Thank you

I wouldn't buy those Pulstar plugs. My dad and I saw those before and looked at the independent testing, and the results are marginal increases at best. Spark is spark, combustion is combustion. Not much to change there, best I can tell is it's the K&N of spark plugs.
From my experience my Autolite plugs work best.

$14 plug... A NGK will be typically a pack of 4 for that money...
