checked the fuses and relays, all check good, no power to the dash at all, no hour meter either. As for the engine, it's gasoline/LPG, and after clearing the tar from the vaporizer, it will rev normally (gas or LPG) until I shut the machine off, then it levels out at 1300 rpms until I again 'clear the tar'. However, there is nothing coming out of the hole other than the pressurized gas from the LPG supply hose.
