To op. I'd modify it just for the heck of it u can never have too much.

Got a gx390 gave to me. Was off of a Crete mixer. 2 questions. Is the counter balance shaft necessary Where can I find a regular side cover

Yeah I missed that. Good luck op

Before you seek more than 5500 rpm's I'd highly suggest billet rod. And flywheel. 36# valve springs are overkill. 18# should get you plenty of rpm's. Granted the spring pockets may require cutting to prevent coil bind. Anytime your replacing with heavier springs you will want to get stronger...

What's wrong with it

The stock predator engine with that tav should hit 50 with the governor removed maybe without it. I purchased a predator hemi and broke it in. It surprised me with the torque it had. Very worth the money

Anyone ever use the hr series Tilly carbs?

**** who cares, slap er on a yard kart and run the ***** outta it

****, have it sleeved,its easy to do but if you cant come up with one i have a coolbore (aluminum bore- no sleeve) block that i was going to run in the opens this year opened up in the intake and its bore size on (my gauge says) its 2.5930

Your kidding.............:popcorn:

I thought the bronze bushing on most clutches were oil impregnated.....other than that synthetic will work just as well as regular oil......the 4 hour thing is good insurance as stated above

I hope your running a clutch/chain guard on your engine, otherwise one day you could lose that elbow and feel like :censored:

Garry Fisher has a really good book on building flathead engines as well

and for the record i think ALVIN L NUNLEY should see this

;1Ok i just watched ALL videos of this guy........ for a yard kart......this would be perfect....for the average guy that can read a txtbook.......and use a piece of sandpaper....never smooth the ports......fuel atomization is key..........never seen him go for advanced timing!? .....race...
