Currently doing a few mods to a-4. It had a Christen wobble oump as an aux pump for 25 yrs...since new. I don?t want to wobble if the engine mech pump fails. I?ve removed the pump, installed an elec Facet plus a new Van?s gascolator and selector valve. The Christen has all above parts as part of the pump. Also disabled the primer, as the Facet does that job.
PROBLEM: Now the engine won?t start.
QUESTIONS:
1. On average, how many seconds do you turn on Facet to prime before starting?
2. Do you hear a noise change in Facet when engine is being primed? I heard no change.
3. No gas ?overflow? on the ramp from carburetor .....as if the engine was flooded.
4. After priming for about 15 seconds, while trying to start engine it gave me a sensation of being flooded.......meaning the prop turned slower....as it seemed to be flooded/loaded up. Battery is good.
My friend on the ramp while I tried to start engine thinks the engine is not getting fuel, because there was no gas on the ramp. I ran out of daylight yesterday, so I put the plane back in the hangar.
Should I prime for 6-8 seconds and then see if gascolator has fuel by trying to drain via the quick drain?
The engine always started easily with the Christen pump setup....only used the primer when engine was cold.
What?s going on here? All comments/advice appreciated much.......Marv
