    not likely. even with the plastics removed the carb choke lever will hit the top tube. if you are set on a mtn bike, have you considered friction drive. bikeberry has a good sizing method. i have mine on a mtn bike but it has a curved top tube; it is possible to get it on that bike but there will be a nasty tilt that you will need to compensate for. it is a big hassle to do so.

    If you tilt a 4stroke at all your going to have oil and carb issues. Carb float won't work properly and you could starve the upper engine of oil due to the slant.

    no no. tilt it on the other axis, parallel to the bike. this is the way i fit it onto my mtn bike after removing all the plastics. it is a minor tilt caused by the choke lever. now, that i am thinking about it. i might chop it choke lever down and make it into more of a dial rather than a lever.

    just modify the oil flinger to suit and make a new intake plenum. I've run honda ohv motors 90 degrees from stock with no issue

    A Honda gx 35cc yes. Explain to us how a HS 144f carb works tilted 90 deg, Also explain how the oil slinger works when the engine oil is all pooled up on the side of the motor tilted at 90 deg. I'm going to make some popcorn and don't want to miss this explanation........ the gx 35cc has an oil pump with pick up tube I know to make it work. Dunno how it doesn't run out in the oil reservoir when the oil is being cycled, only holds 4 ounces or so. Your idea Butre I'm clueless how that would work.

    I'm talking GX200 specifically.

    you need to make a new intake plenum so that the carb isn't tilted 90 degrees, like I said, and you need to modify or replace the oil flinger so it picks up from the side instead of the bottom, again like I said.


    I have no experience with huashengs in particular, but it ain't rocket surgery and they're all constructed roughly the same.

    I've seen vertical shaft engines modded to run horizontally, just needs what butre described.
