Starting issue

K jet when starting from cold, fuel pump primes then when cranked it tried to fire then nothing… but if you turn ignition off then on again and try it will fire up?

Once warm its fine
Also ive noticed it will idle slightly higher at just over 1000 after a run, if turn off then restarted it idles just under.


New injectors, filter & fuel

well I discovered the whole cold start system/enrichment  wasn't working .
