Thanks for the reply Banjo! the fuel pump I'm currently using is the one originally from the 4K-C engine. I’m not quite sure if it has no faulty or whatsoever. I might try swap it with a different fuel pump. Maybe from my 3K engine since i am pretty sure that the previous one works well. Once again thanks for the suggestion. Will reply to you once i have the results 🤝🏻

Thanks for the reply, guess i should’ve stayed with the original distributors 😭. i recently payed someone to inspect the car and one of them said that he’s 100% sure that it’s a valve problem. I don’t really know how and why since i just started to get into cars after the KE30 was handed down to me by my grandpa haha

Old dizzy’s pin wiggles already. Fuel pump is all good, good fuel flow from the carby as well and ive tried using the old carby, still the same problem. It jerks whenever i pickup some speed and yes it idles smoothly

Thanks for the reply Banjo! I don't really know how to upload the video here, by any chance is there any other way for me to contact you? My instagram’s @/juoone btw! The engine have 1 off 5K carby. Original distributor ( non electrical, but i just ordered the electrical distributor last night hehe ). Idle is fantastic, sounds good for me. The problem occur whenever i start to pick up some speed. It jerks all the time. The plug’s insulator color is yellowish burnt. I’m planning on getting someone to come and check it for me tho! Still don’t have the time since I'm quite busy with school still hahaha! I’m from Brunei Darussalam btw, a tiny country based in south east asia 🇧🇳 ps: don't mind the messy engine bay haha

Hello everyone, I'm new here. Recently i just swapped my 3K-H to a 4K-C engine with oversized piston, 5K carbs, 5K starters, 5K distributors. Engine was fully rebuilt by a mechanic whom i paid to do those job. It has been a month ever since i swapped the engine but i still can't drive the car due to the constant jerking when moving. Sometimes the engine died whenever i change gears. Really in need of help since ive been putting so much time and money to get this car fixed!
