Most popular engines have a 37.8mm distance between mounting holes.

However  some  engines  (for  example,  Picco)  have  a  smaller  distance 

(37mm).  If your engine has the smaller distance between mounting 

holes, you need to enlarge the mounting holes (for example, make each 

hole ø0.2~0.4mm larger) to allow the engine to fit the engine mounts 

properly.

8. ENGINE & CLUTCH

Adjust gear mesh so there is minimal 

play between the gears.

Too tight gear mesh will put excessive 

strain  on  all  parts  and  damage  the 

parts.  Too loose gear mesh may result 

in stripped gears.
