while having no problem starting first time for the day, my trooper has developed problem starting once the engine is hot (driven at least for 20-30 minutes)
what's odd is that even if the first engine start occurs late afternoon, it starts fine, although with low initial revs (at 300 to 400 rpm) but at least it starts, after that, it may take 12 tries to get started
there's no problem cranking, starter is almost new and alternator is also new
so far, have changed plugs and the fuel filter but have not emptied tank (in case of a bad batch of fuel)
any other simple things I can look for? if suggesting an adjustment, kindly provide a little more information (ie. if you suggest to turn humdinger counterclockwise while aligned toes to the north pole, I will likely get the toes part right while not locating humdinger)
