RE: [T3] SOS someone help before i nut up and bomb my vw


Holy cow, I'm having the same problem on my dual carbed 1600 dual port motor.  1 and 3 are weak, yet have good compression.  I've tried flat sanding and notching the manifolds, and all the usual spark plug shenanigans and I've also been suspecting an irregular cam. I'm stymied.  This is a recently rebuilt motor, with a c/w crank.  I built it myself, and while I make no claims at being an expert I did take pains to balance the rods and check the deck heights correctly.  That doesn't mean I did it right, but I think I did.
Rings not seating?  Oddly coincidental valve seating problems?  Enquiring mind wants to know!!

I used to think that I was a good technician until I started having this 
problem with my square.  Two cylinders(1 and 3)hardly fire at all and 
the other two fire normally.  Compresssion is even all the way 
around(135psi).  Spark is present and blue at all clyinders.  I thought 
the carbs might be letting more gas get to the rear cylinders, so i 
reversed the carbs( stock 32s). no change .  iswapped the spark plugs 
and wires and cap. No change.  I concluded the cam was messed up .  
Swapped it too.  No change.  Why would the front twoo cylinders get no 
power while the rear ones do?(The spark plugs don't even have any color 
on them?)
