engine miss cold

[xm302]

i have a carby tb42 patrol
problem i hav is when cold it will miss badly
once warm, it runs great and doesnt miss a heartbeat

i hav changed plugs, leads, cap and still the same

i am starting to think a possible fuel problem?

if i hold my foot flat and wait for it to get up the revs it will then run better,but still slight miss

any help much appreciated

hey mate, does your engine have an automatic choke, have you checked it out?

[xm302]

yer it does, what goes wrong with them?

Hey is there any smoke out of the tailpipe White / black / blue when this miss is occuring ?
Could be - Leaking headgasket / cracked head - water burns away and she runs fine is it loosing any coolant ? is the engine oil milky ? there would be steam coming out of the tailpipe.(white )
the choke would cause black smoke
and blue would be oil contamination or leaking upper cylinder lube if fitted . good luck with this lot !!
