Hi everyone, just recently caught a ke20 with 4k engine installed.
Stock engine, I think it's a 5k carb and the distributor is still using points.
Sorted out the aisan carb idle issue, thanks to helpful topics here.
I got a performance issue though, in 1st gear it won't past 5k rpm, on 2nd 4.3k rpm ang goes lower on a higher gear.
I'm not familiar on how the 4k performs normally ( stock ), but I think this far from stock performance.
Here are the things I've tried:
- timing is now 10 deg btdc
- made the secondary open mechanically instead of vacuum activated.
- installed msd ignition box (sci)
After these mods, it made it accelerate faster however, I'm still experiencing the same cut offs.
On the carb, it no longer has an idle fuel cut solenoid, the points are gapped .45 as suggested.
I'm thinking of removing the msd and carb mods, as it did not help the limiting issue.
Could this be something internal in the engine? Valve springs, cam timing etc?
Hoping to heard some suggestions.
TIA!
