question

[Rotore]

i went to the junk yard to get the kolher engine but i it was just too much to get it out and the carb was trash. so i walked around a bit saw a small go kart with a 4hp Robin Subaru engine again the carb AND gas tank was is trash but i bought it for $40.

SOOOOO now i have a doner kart.

But i have a 60T axle sprocket and am going to go for a 10T clutch, I will remove the govener and free up the exhaust with a staight pipe.

Question is will it have enough power to move me and a frame made of angle iron off a bed frame?

If not what can i do to get a bit more power? BTW

engine is a Robin Subaru EX13, 0.126L , 126cc

Should be fine, my ****ty kart with a 5.5 tecumseh had a 6:1 ratio and would push me 30mph governed no problems. The engine was bone stock, had a messed up carb and ran rich, and the worst of all was a tecumseh. I road mine off road, on road, up hills, did fine as long as i got a little running start before the hill.

any suggestions on getting a bit more power out of this thing?

I took off the valve cover to inspect the valvetrain pretty clean BTW and saw that its valves are actually bolted to the rocker, is there anyway i can adjust them to get more lift?

I dont think they would be directly bolted 2 the rockers, maybe its just an adjuster for them? You really need a different cam 2 get more valve lift, you could make sure all th clearances are perfect but that really wouldnt make any difference and anyway, you dont want more valve lift unless your doing higher revs.

i am aiming for 4500-5000rpm

Suburas are governed at 4000 rpm, so that is feasible. There isn't many after market parts for them internally though.

Maybe you can find some honda 1:2 rockers that will fit?
