Check out this slick new combo product from Marcus Yoo for all TAYLOR engines running the V2 62mm clutch. 
 
This design offers a very solid solution to adjustable gear meshing, instead of having individual engine mesh inserts. The whole plate acts as a sliding mesh brace on the bottom of the chassis so youll never need to mess around with 19/20/21T etc inserts but can get the perfect mesh after changing your gear ratio every time!
 
Also this mesh plate doubles up as a piston stopper/clutch holding tool as shown in the photos!

The plate is also supplied with a billet centering tool which you can use if you wish to accurately drill extra holes in your chassis for extra clamping force for holding the engine still, ideal if you suffer with engine bolts coming loose.
