4a084

Postby nebraskaairboater » Sun Dec 07, 2014 9:47 pm

I just picked up a couple of 4a084 generator motors cheap. One is complete the other is missing a head and starter. I'm not sure how to try and start the one that's complete. Any advice would be appreciated. If I can get one to run good I plan to start a mini build with it.

Thanks,

Dan

Fuel: check
Compression: check
Oil & filter: check
Spark: check.
If the mag is bad, most any other 4cyl mag will work, SaturnSurplus.com had some new ones for about $150.

The 24V starter will turn on lesser voltage, only slower.....it's easy enough to series two batterise together for 24V.
Often engines turned in or otherwise in storage will have all the fluids drained; pull the plugs, squirt a little oil in each cylinder, if the crankcase is full (and filter attached) spin it over to get everything lubricated & flowing, would be a good time to check the spark on each plug while you're spinning it over, make sure the shut-down switch is working and "on" when you check for spark and to run it.
May take a little while to pull fuel through it, seal the cylinders, get everything wet, but shoud all three things cometogther it should run!

I have an opportunity to pick up a broken 4 blade warp drive setup with the plates and all hardware. The blades are shot but replacements are cheap. Would this work as a 2 blade for the 084? Either with reduction or direct drive?

Thanks,
