YS .45 2stroke
 

It spews fuel out of the front bearing. I just acquired it from another modeler who couldnt seem to fix it. I was thinking of rebuild and checking the assembel of the pump, bearing, crank.

Any other sugestions

There is too much clearance between the crankcase and crankshaft, likely caused from running in dirty conditions. Replacing the crankcase may be necessary.
