up top mountain -- Sourthern Ca.
Installed my Subaru 35cc friction drive on my mountain bike.. It is not as level as I wish it could be.. Leaning towards the back end a little -- thus going up hills -- it will be even more un-level... I am thinking that this should be no big deal since my weed wacker used here in my yard get's put into many different positions while in use --- I guess the question might be - are these small engines using an oil pump or a splash system ?

Is it a four stroke? Your weedwhacker is a two stroke so you mix the oil with the gas. At any rate it's not problematic up to a point. Where that point is I don't know but you'll know it when you're there cuz a ton of smoke will come out the exhaust. But maybe I'm wrong.
 
Hi Norm -- it's a four stroke.. Weed Wackers are also made in 4-stroke these days. Well I had one long ride today -- up some pretty big hills -- seems not to be having oiling problems -- ran good -- no smoke -- no knocking -- my top speed appears to be 23 mph -- just broken in...

Robin Subaru engines use a oil mist lubrication system.Look around at www.robinamerica.com .where you can learn more.

I went to the site --Thank you duivendyk ------The Subaru micro engines are designed to run in a wide range of positions. The patented oil lubrication system is elegant in its engineering simplicity. The natural pressure changes in the crankcase caused by the piston movemovement in the cylinder are harnessed to pump the oil throughout the engine. Thanks again and Happy Riding from - Mountainman
 
slight tilt -- but -- not upside down

yes -- wide range -- but -- not upside down

things been running good for a long time -- with slight tilt

ride that thing
 
One simple change I've done for that is maneuver the U bracket so it is on the inside of the seat stays....it pulls everything forward and levels it out a tad.
