with other life issues, I have neglected started my port
2GM20 (about 1,000 hours on it) for quite some time, was running fine when last run. seemed to get
fuel at the injectors but when I removed the intake silencer, it blows back seriously thru the intake. Spraying WD40 does not get it to fire. I fresh charge on
battery, turns over nicely. I pulled the valve cover thinking maybe a valve was stuck open but they all seem to be operating correctly.
Water cooling hose is disconnected so not
water in the intake issue. What am I missing? It is the blowback that has me concerned.
