My truck ran ok during the first tank, but after that the truck has progressively run worse. It's to the point now where it won't even run. I have tried just about everything. I have called Hobbico and they are planing on sending me a new CDI box whenever they become available. I asked when that might be and they had no definite answer.
So far.....
1. Reset carb to factory settings (this has been checked and rechecked more than I can count)
2. Pull plug and clean
3. Replace plug with new
4. Pull plug and close gap from .6mm to .5mm per HPI updated recommendation
5. Pull motor from chassis and verify setting on ignition sensor (it was ok).
6. Troubleshoot for air leaks (none found)
7. Try running no air cleaner
8. Remove restrictor on opening of carb
I'm at a loss.....and HPI really isn't responding to my questions. Hobbico has been decent to deal with but they have no idea what to do and like I said there are no parts available yet.
