definantly worth doing a compression test. If youve got valve problems or just worn rings on one or more cylinder it wont run evenly or smooth without major compensations in power and economy. Do a compression test, sounds like your not getting enough compression on 1 and 2 to get a good combustion. Does the exahust sting your nose or smell rich (dont take too many whiffs or you will die from the carbon monoxide). Put ya hand infront of the 1 and 2 exhaust and pull it away after a few seconds and smell ya hand for petrol...
if it was me...
id just rip off the head on the 1 and 2 side, check for cracks between inlet and exhaust valves, this is VERY common on TP 1600 engines
replace rings while the access is there, better yet, do all 4 piston and rings cos if its black and oily ya arnt burning the fuel... or the oil sliding up the sides of the barrel! if ya do all 4 cylinders then ya know ya got a reliable engine
but seriously, theres no other way around fixing your car if rings of valve wear is the problem

nope still wont idle.......but it appears to be running on 2 cylinders so i dont really blame it......it does however feel like it wants to idle but just cant keep it up with only the 2 cylinders.
ill pull the rocker covers off tomorrow and have a good look at the rocker action and see if i can pic something up.

Nick if you can get the engine round to my place we'll pull it apart and have a go at it, as the wife can't understand how I can drive to Caloundra to play with a veedub engine but can't go to Maroochydore to go shopping with her😂
