HEMI 212

[Rat]

I think I've got an odd duck.
I have a Hemi Predator (came with new house and a briggs flatty powered kart) but I'm not sure of some details... need a Predator guru.
Mostly I just want some insight as to if it is in fact a Predator212 Hemi, or if it's someone's franken'gine.

It has a SMALLER flywheel and flywheel taper than my Husqvarna 208 (which is compatible with nearly all Gx180/200& clone parts) and has a manufacturers sticker indicating it was EPA compliant as of 2006 on the shroud.
It does have the 25-I/27-E valves, lash caps on both valves, adjustable tappet style rockers, but not automotive type keepers.

I'd say it has weak or worn stock valve springs because I was able to mash the springs and seat the keepers on by hand.

I disassembled it due to unknown condition and didn't see anything abnormal or damaged anywhere inside.

I of course yanked all the gov'nor guts and low oil kill out, then plugged all the holes after a good scrubbing. I cleaned up the port castings, and scrubbed the case a bit more. I shaved the "OHV"
raised letters off the cast aluminum valve cover (because why not?) I'd like to etch, decal, or paint "Hemi" across it instead.

I have not heard it run yet because the recoil is toast, and it doesn't have electric start or exhaust (yet)...of course it's not bolted to anything either.

is it missing the flywheel? I have built 4 NON hemi predators. If I remember correctly both hemi and non hemi engines take different but specific flywheel.
Meaning they fit one or the other but that engine only.

just checked the Go Power Sports website. Hemi predator flywheel is its own
part #, so nothing else is going to fit it correctly.

Good to know. I've seen it said that the flywheel taper is bigger than all the others but this one is the opposite.

I figured that much out because a while back I had gotten a GX180/200 E-start kit for my Husqvarna 208, but didn't use the flywheel because it was already set up for it (unfortunately came with a 2phase 120ACV starter motor) and had a better quality flywheel on It... so yeah not only is the flywheel diameter smaller, but the taper is as well.

Yea, it’s a hemi. Stock valve springs are easily compressed, so no problem there.

Sounds like an excuse to slap 18lb springs in it, I guess my Husqvarna 208 must have had 18 or heavier stock because they would not compress by hand for anything and I ended up rigging up something so I could pop them to work the valve pots and clean out the ports as well as get the keepers back on after. IIRC I used a cheap pulley tool of some sort and a large open end wrench that just barely lipped the top of spring coils

The flywheel isn't missing, just the recoil cover is. I actually found one of the starter cup pawls wedged under the flywheel when I knocked it off

I would rather put an electric starter kit on it than put a new recoil start assembly on the shroud.

Curious if anyone might be able to verify this tidbit I found over on narracing?
