Good news bad news at the office, the Cadillac owner can't afford to have me work on the bad wiring harness so he is towing it off.
The bad news I get to pull the cylinder head off this PT Cruiser. The car was built by so magazine I heard. So I spent half the day just getting the Wippel Charger off. :thud

This fancy aftermarket set up has a very bad port match up :scratch

It does move the injectors to the bottom of the ports.

That wasn't so bad. half a day work and the head is off.
4 bad intake valves. Number 4 piston looked funny so I pulled it out, but didn't show much. But this got me to thinking, generally when you go to forced induction or nitrous one should open up the ring gap. Something tells me that this aftermarket kit probably didn't address this. :dunno2

When I told my builder I wanted forced induction, he had a cheat sheet which indicated how much to gap the rings. I know it was based on pressure/PSI, but off hand I don't know how much the gap was.

Here is an article I found:

My 68 Datsun roadster had the same carbs. Once I rebushed them, I got the carbs adjusted pretty well. But it did take some fiddling and lots of reading.:D

Put a sign out front,, No foreign cars please.....:crazy
Why,Those Datsuns were simple and reliable.There's no real problems with the early 240 carbs,the early 74 260's were troublesome due to "smog"restrictions,they went to a better carb design in mid 74.Looks like a good place for a W engine.
