    I have an 8hp Honda engine on my Emglo compressor. It's brand new and will start on the first pull, but when i put on my drive belt (dual belts) around the compressor pump it is very hard to pull and won't start. The pump is not seized and turns just fine. The compressor just won't crank with the belts on. Any ideas? Is this a common problem with larger HP compressors? It's a v-twin compressor pump capable of putting out a good amount of air.

    Open the tank drains when starting. That will help allow the engine to run under less load until it warms up. Also, do you have the idle down system adjusted properly...when there is no pressure in the tanks the engine should be trying to run full speed. Make sure that spring plunger thing they use is pulling the throttle lever to full speed.

    If none of that helps...I would start looking at the pump.
