Hello everyone, I'm a land surveyor and use my Uforce 600 daily. I have about 260 hours on it and we work it in extremely dusty/rough conditions. I have been extremely happy with it. Just took it in for a 100 hour service and since then it has started having trouble starting, idling rough and stalling. If the accelerator is pressed it runs fine but still starts really rough. Sometimes takes multiple attempts to start. This didn't happen immediately after service but very soon after. Any ideas how i can fix it? I have a huge job coming up and the shops are weeks out. I know nothing of engines or vehicles but will work hard on it if that helps. Any info I can provide I will and thank you for reading.

PS if the emergency brake is engaged when I start it the problem is horrible, it will barely start. As soon as I disengage emergency brake it helps. I have had this problem since day one but thought marine it was a feature.
