hi guys,
i have this trimmer engine that i want to "hot up".
specs:
talon trimmer
XTM full crank 28cc
1HP stock
piston port type (normal)
cheap carby
pull start on one side, flywheel on other.
exhaust and intake ports taper inward.



what i first plan to do is chuck out the carby because it has no tuning screws.
i also machined the fins of the flywheel.
i have been told to double the exhaust's stinger size so i did.
the intake port is taperes from a large rectangular hole down to a smaller one.
the exhause is tapered outwards.


oh and we are gonna make a prop hub ourselfs. (half done)

any mods should i definatly make that are garrenteed to work??
