Hello, i have probably weird question, but my LRP Z.15s started to leak in that place between crankcase and cylinder head, now i can`t figure out what`s wrong but my guess is that cylinder head screws are loose, but i`ll get the hex tool to open it tomorrow. Engine is still running, but it`s extremely hard to start and fuel is making everything filthy. What to do? what should be checked or replaced? Maybe someone had the same problem.

Just tighten the head bolts.

You are sure it is becomming from ththat point?
A leak in the exhaust connection can cause the same issue

Ok, today i really found out where the leakage is and comression status. There is really huge air/fuel leak at the bottom of carburatior and could this be reason why its hard to start it. Or why it has lost major part of it`s compression.

BTW. its .15 engine some lrp.

This is how we fix our compression leaks. Go to an auto parts store and get the high temp red gasket sealant. It's the same stuff you use on your intake gaskets on you real car. Take you carb and/or your back plate and put a thin amount on the carb neck where the oring is and put it back in. You can do the same on the back plate also. Wipe off the excess. This is the 2 main sites for leakage. Hope it help for you.
