Maybe you have a /6 tach?

Posted by: brp914 May 29 2006, 11:14 AM

dang...gonna need some extra tall jack stands after all that.

does it idle ok? if so, measure intake vacuum. you should get atleast 14inch Hg. the idle air adj. screw should be nearly closed.

measure fuel pressure - should be around 28psi

good luck

Have you checked the rotor, could it be a rev limiter type to 4000rpm??
CCLIN400rpm

I would also check Craig's tip about the rotor...

Posted by: brp914 May 29 2006, 12:41 PM

if your valves are so out of adjustment that it wont go past 4k, it wont idle well. if your valves are excessively loose, that engines gotta be making hellaciuos racket. and if excessively tight and driven that way for a while, your valve train is likely bbq'd along with those ribs.

is this a djet or carbs?

check the trigger points.

Something else that could cause that is a warn cam and followers. How many miles on the bottom end?

Q : What did you feed it ?

I wouldn't do much more than idle after a plate like that !

Good luck.

i hope, for your sake, it's a timing issue.

if it is a crapped out cam i know that sir andy had a good used 1.7 for sale for a respectable price.

Does the throttle open all the way?

Posted by: JOHNMAN May 30 2006, 11:54 AM

Does it break up at 4000 RPM real badly?

Swap out the coil for a known good one and see if that might be it.

Posted by: ptravnic May 30 2006, 12:44 PM

I don't know much about what a bad coil acts like but they're pretty cheap - maybe $30 or so.

Update on the car....
Rusted brake line has been replaced.
Master is leaking like a ... lets just say big puddle
Gas pedal to be welded/repaired to avoid sticking - Wow no brakes and sticking throttle that was
Fuel pump connection was not conected it was arcing at the pump.
More on that tomorrow not sure it will fix the 4000 rpm thing
It's gonna run nice real soon
