Default Newbie with a gx390

Hi,

Total newbie here from the uk

Got a gx390 13hp engine and was looking on the Internet for info regarding clutches and its led me here

Now need to dream up a project to build

So beware I'll be asking stupid questions but promise to use the search function first

Welcome. Unfortunately with a 390 you are going to have to get an expensive clutch. You have a 1" shaft. If you get a torque converted you will need to get a comet 40 series, of something equivalent

There are no "stupid questions" so, ask away...

I suggest you start searching local online classifieds for an appropriate rolling chassis...

If you maintain it, oil it and dont over tighten the chain, use the right gearing it should last you a while.
