Hello Darren .

This is a reply from Australia . According to my OPS Catalogue ( 1993 ) this motor comes with 2 different head buttons , P / N 5961 - Low nitro and P /N 5962 High nitro - so there is your first thing to look at . Regarding the mounting method for the remote mixture , i used with no obvious problems a BRU - LINE pushrod boot retainer / stamped aluminium part on a small piece of angle . I did not use as much nitro as other competitors who said to use large fuel lines to enable the engine to run fast and hard . As for the original carby , I replaced it later on with a adaptor to mount a K / B 67 Carby which gave me a low speed mixture . 1 thing to be aware of - IF YOU RUN THEM SLOWLY , THEY HAVE A BAD HABIT OF FIRING UP NORMALLY AND THEN GOING INTO REVERSE ROTATION . Good luck with it , I don't have my motor anymore , still have the adaptor and carby though - compliments of some 5 FINGER DISCOUNTS 1 YEAR AGO , along with several other OPS Motors and my 35 CC MATHE .
