hello wonder if anybody can help me before i start changing bits on it,when starting it it sounds like its running on 3 when it fires up then clears and sometimes when starting it it just keeps turning over for a while before firing up.cheers

 

i would start with a set of plugs/cap and rotor arm!is this from hot or cold?

 

it does it from hot and cold,it always seems to do it when its sitting ticking over then for the first few seconds when giving it some revs it sounds like its running on 3 then clears but will give them a try mate cheers

 

Also make sure the leads are firmly connected at each end
