Been having this elcamino for about 2 years but i never went in depth with it why i ran like crap. Popping out the carb at high speeds. So recently i made time to look at it (blame it on the covid19)
Went around pulling plugs 1 by 1 to see if they would all make the engine bog down. #1 and #7 seem to have no change when pulling the wires off. Swapped wires and plugs around to see if the problem shifted to a different cylinder but it remained at #1 and #7.
Did a dry and wet co pression test on those two cylinders plus a good cylinder (#2) to see what the differences would be. Here are the results.
#1 dry:50psi wet:60psi
#7 dry:90psi wet:105psi
#2 dry 135psi wet:150psi
Is there something i can try before removing the head to see exactly what's going on with it? Here's what I've done in the past week with it;
Started off by changing intake gasket because it was suspect (i previously had used the plastic strips the gasket kit comes with)
Adjusted valves while intake was off (each cylinder at tdc, tighten until 0 lash, then 1/2 turn more)
After doing the dry/wet co pression tests i took a hammer and a block of wood and tapped on the valves (removed rocker arm for this, then adjusted valve with engine running)
Exhaust does not smoke at all. Engine oil does not look like chocolate milk.
Thanks guys, hopefully you guys can point me to what to do next.
