Hi all,
I picked up a 1j chaser a few months ago and ever since owning it, it has always blown quite a lot of black smoke under load and general driving. I’m aware that this is fuel related as it reaks of fuel fumes. Recently it has started to detonate under load which emits even more smoke and the engine hesitates for a few seconds. My recent oil changed showed no flakes however the oil also smelt quite fuely. I’m getting a wideband put in this week so hopefully that will be able to give me an idea if it’s running lean or not but I not to familiar as to why it would be detonating. It has an fpr fitted and on idle it’s running 35psi. Any help or suggestions would be much appreciated!!!
TIA
Edit: it also has a walbro 460 fitted
