Mine did something similar in the balze running veg was a fucker to get goin in morning especially this time of year when its getting cold, when did you last change the fuel filter i no its nothing major like previous answers but this fixed my problem as the pump was struggling to drag fuel through, also check the pickup in tank.
May be a long shot tbh but if all timing holes line up cant think of anything else, im unsure what the valve clearances would need to be but dont think would make much of a difference on these things tbf but i may be wrong
try running on derv for a couple of days see if it makes a difference
also drain any water out of filter Ginge told me to do this other week and has 90% solved white smoke on starup
