I have a partner chainsaw mod.351 which is allmost impossible to start, once running its ok but if it stops for any reason its back to normal,this problem is with the engine cold or hot. could anybody please tell me how to tune it, I have phoned the local lawn mower repair experts and they refused to look at it and said "they are a load of crap" please/please/please/ can anyone help me to prove this man wrong

Early Partners (yellow) were awkward....this was usually due to them running hot - which of course wouldn't affect a cold start! Use a new plug, clean the air filter and set the slow running screw 1 1/4 turns out to see if that makes any difference.
