JLO Rockwell 297 Won't Dtart

[mick wick]

Having trouble getting JLO 297 to fire up. It is getting fresh fuel has 125lbs compression, throws 1/4" spark and will sap the heck out of ya!!!! Exhaust is not plug or blocked. It has not been started in a couple years. Any ideas this one has me stumped. You would think I don' t know anything about mechanics. The only thing I am thinking is compression low. Any comments or ideas greatly appreciated. Thanks Mike

Check for Sucked crank seal ! If that leak by it will Not run !!
To test spray some lite oil in the intake port then try to start. The best way to testbis with a leakdown tester ported into the crank cavity. Or check for vacume on the intake when your cranking it over.
Hope this helps ?

Thanks for the reply, a local person told me to check the seal also. Ran great when parked but seal might have dried up explaining my problem starting. Thanks again.
