Having trouble with my skywriter
As the title says, I'm having trouble with my Sullivan Skywriter. It works perfectly on the ground, with the engine off. When I crank the engine, it does not work. It will pump for about 2-3 seconds every once and a while. I'm running a 100cc twin, the smoke pump is set up with a 9.6 volt battery, and a heavy duty switch. I have check my plumbing and connections. All are good. I can pump a full tank out on the ground without the engine running, but as soon as I start the engine it stops working. Anyone else had a problem like this? Any help would be great.
Thanks, Canardman
