Though I have no specific knowledge of your application, generally in similar situations I've found a good quality gasket sealant like Permatex or Sikaflex products will give a good result - most auto stores should be able to provide correct product advice.

To put cases together you need a anaerobic sealer or its going to leak.

I might add that it's a good idea to be concerned about making a good seal on all crankcase gaskets. This applies to all two-cycle engines... there must be a very tight seal on all those joints or the engine won't run right.
If a four-cycle engine's crankcase isn't sealed well, it might just drip a little oil but run fine. If a two-cycle engine's crankcase isn't sealed well, the fuel/air mixture won't be pumped into the combustion chamber properly and the engine won't run right.
