Thanks Neal,
I am an RC airplane guy and have never had to replace bearings after 2 gallons on my 15+ airplane engines. Also 16 years ago, I had an old Picco (that I still have) that must have had 8 to 10 gallons before I tore it apart and the bearing was still in much better shape then the one in my P5 after only 1.5 gallons?
Just seems odd to me.
I found my problem...When pulling apart the old bearing, I created small burrs on the inside of the crank case. I cleaned the ones on the side where the rear bearing sits but not the one in the crankshaft hole.
So when I put the crank back in, it was rubbing slightly on those burrs, giving me the impression that the new bearing was scrap!!!
I feel like such a diouuush bag

. Off road car engines take ridiculous amount of abuse compared to plane engines. Having said that 2 gallons is a bit soon.

i run a 9886/41001 or a 9853/41001 ...both run awesome............. then I will run a 086...which is similar to the 9886, but more abrupt, on/off...........The JP2 probably would work good.......2058 works good.......2013 would lose some top end, but would have balls for days........never tried a RE12..so cannot comment...but if its the one thats a copy of a 9901 it may work really well on a Nova 41001 manifold

I don't know which one it was as Kyle is 2000 klm's north of me and I didn't ask the question when talking to him but with two solid week's of testing and being rained out last week end, Im sure he is looking forward to more testing this weekend, cheer's

Thanks! Guess I'll get started with the orange one when I receive them and then try the medium one.

What were you using to check the idle gap? Are those just paper clips?

I purchased BHP blue steel rod in 0.7mm, 0.6mm, 0.5mm a long time ago and just use the 0.5mm to set my idle gap for racing and the 0.7mm when breaking in a new engine, wish I knew then that I was going to need a 0.4mm one
