How much does that bad boy weigh? Should be an interesting mount to the firewall. Please post if you get it running. I don't know if the copper tube to the carb will keep the carb cool, but give it a shot. The pipes are interesting, did you solder them with regular solder???
Don't know on the prop, but at 127cc-get one off a ultra lite!

Hi,
It is 9lb with the flywheel, 6lb without. Looking to going with electronic ignition.
No, all the solding was done with silver solder it has a higher melting point then reg. solder.
Looking to start with a 26'' prop. what do think?

Check the mower blade diameter and pitch that was on it that should get you close. LOL.
