Some Magnum engines do have problems. You will do well with an O.S.
I still have my magnum 52 and so does onother guy at the field. We decided to keep 'em 'cause we don't know anybody we don't like to give 'em to. [:'(] my low end needle can be seen rotating while the engine runs. locktite did no good at all.
get an OS 46 and have yourself some fun at the feild for a change.
Send them to me...I'll take them..both of them and all the magnums or non OS engines you have too.

I have teflon tape or spare O rings somewhere.lol
