12a j port not hitting full power
 

Hi there I have a 12a j port with a 4 barrel carby on it.dissy timing with points ignition.gilmore belt for timing marks.fuel pressure is at 5pounds in to carby.starts good runs ok but dies out wen I try to hit my secondary’s.not sure if it’s my timing or my jets in carby

We're not sure either.

Gilmer belt for timing marks?

What?

I don't know what you mean by "dissy timing" and "gilmore belt for timing marks" so I'm going to suggest you check the timing (and separation between leading and trailing) I guess.

hay dont worry have got it sorted.now i have a s3 rx7 gearbox and i snapped the driveshaft yoke off.and have not been able to find it.was woundering if sum1 can tell me the splin number on output shaft on gearbox.as car is about a hour away from me and cant get to it atm

You're wondering the spline count of the front yoke of the driveshaft for an S3 transmission? Try consolidating in your other thread about the snapped driveshaft, will be easier to follow there.
