Morning all. I got a 91 vitara 1.6 on a carb. Starts fine, idles fine and revs all the way out in neutral with out skipping beat but when in gear it bogs down and cuts out especially under full throttle. Give it a second or two and it fires straight back up and runs fine until you try to drive it again.

Changed the fuel filter with no difference, also have new vac lines on order to replace the lot and a new ignition coil.

Any help would be greatly appreciated

Thanks
