  1. Update on the compression test: 1 = 140 2 = 135 3 = 160 4 = 150 From the advise of allteza, looks bad. I just got the car almost 2 months now, first thing I did was give it service, change points and condenser, cleaned the carb, new plugs, cleaned the battery terminals, I can't reach the grounding points on the engine so I added ground wires. Batt to chassis, and chassis to engine. Changed the brake fluid and serviced the brakes, drained the old fuel, changed oil and filter. I think the only old fluid in the car are the gear oil for the tranny and diff. Before I got the car, it was sitting on a garage and was not started, driven for atleast a year said the previous owner.
  2. The dizzy advance part I have no idea, but I checked if it was advancing while I was timing it. It does move, without the vacuum line, while revving it. If standing still, it seems to rev past 5k rpm, I can have it reach 6k but just a peak. I release the accelerator once it reaches 6k cause I'm not comfortable, seems like I'm pushing it too much. I have not heard a valve float on a 4k, so I can't be sure if it was doing it. On the aisan, this model does not have a sight glass to check the float level. I captured it on video, however I can't seem to upload on YouTube awhile ago. Have not checked the the pump capability on the delivery. Looks like the mechanical advance on the dizzy makes a lot of sense at the moment. Will try to look for dizzy rebuilding, unless you guys have some quick guides. Very thankful for all your responses.
  3. 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!
