    I have a staton inc 18 to 1 gearbox with a subaru robin. Fuel filter clogged and I burned it down. I'm looking for a reasonable replacement with more power. I'm 210 lbs and want to do 35 mph so Im thinking over 2 hp. I have seen some zenoahs Im interested in but am unsure what size clutch the subaru used.

    Zenoah doesn't have a four stroke in the same displacement class as the 33.5cc EHO 35.
    They do have 2 strokes that could be an alternative.
    DDM has G43L engines cheap. I don't know the clutch size offhand but you could check easy enough.

    78 mm according to steve at ddm. I am having some difficulty finding the measurement on the eho35 so I'm taking it to a mechanic to have it mic'd. I even asked the local robin dealer lol.

    Micd it at 74 and change and the receiver part of the gearbox at 78 so Im thinking 78mm is too big unless i get real clever about boring the receiver larger.

    The zenoah G43L engine should fit your staton gearbox, but it doesn't come with a fuel tank. I just ordered a new Tanaka PF-4000 to put a little more pep in my step from a honda gx35. All use the same size clutch including the robin subaru eh035. I have one of those too.

    Cool! right in my price range.
    Questions, if you do a compression test on a robin would it read low because of the compression release?

    Yes it would.

    I noticed the fuel bulb wasnt filling properly. Bought a very reasonably priced carb from Staton and now its running awesome again. Probably logged over 1000 miles in a week.
