    • Fits an Earthquake MC43 Viper rototiller.
Size: 40-5
This fit an Earthquake MC43 Viper Tiller perfectly. I picked the tiller up at a yard sale for 10 USD and put this kit on it and it runs great.

    • Great Budget Upgrade for Small 2-Stroke Engines
Size: 40-5
This 40mm Big Bore Kit revived my 49cc mini ATV with noticeably better power and throttle response. The parts fit well and included everything needed for installation. Build quality is decent for the price, though you might need to clean up the ports a bit. No instructions are included, so some mechanical know-how helps. Great value for casual use or DIY engine repairs. Just don’t expect OEM-level precision or long-term racing durability. ... show more

Size: 40-5
It's a factory copy so junk all the way. I got one so bad that the think could not create compression to start. I sent it back and junked the unit. I can't get QUAILTY replacements sent to Calif. The Commie state
