Default DLA -56



Hi to all
i have this engine for about a year now i am very pleased with it no problems al all.

yesterday i removed the engine from my plane because i see some oil around the cylinder.

i have found out the most of the screws was not closed hard and i had to tighten them

also when flipping the prop i could hear some knoking from the conncting rod i think it is the needle berring


i removed the carb and couled see the connecting rod and cranckshaft it is looked very cleane inside, when moved the crank all the way up i heared thisknock and see a little free movement up there.

now is it critical for the engine to run like this i use 1:32 oil no 3D flaying?

second will DLE needle bearing will feet this engine?
and can i do it myself?

third do i need to replace the gasketes for this engine and will DLE 55 set will work

thank you
