RN105 22r dieseling?

[Beardog1976]

Hi All, my rn105 Hilux 1994 with a 22r engine is dieseling and I just can not rectify the problem, have installed a weber 32/36 and all eco equipment has been removed. I also installed a older 22r model dissy cap(new) heavy leads and a ea-ed ford coil(see pic) and all works great except the dieseling.

I have spent long hours adjusting the timing and have had her running from 0deg to 12deg with no result, the vac advance is fully working on the dissy.
So now I am reaching out to all you Tojo fans HELP.

I assume when you say its dieseling, you mean its running on when you turn off the car & if that's the case it can be caused by a lot of things, some things are idling to high, running to lean, hot spots in the combustion chamber causing the fuel to ignite etc ..

I would say the carby you pulled off would have had a anti dieseling solenoid to stop this sort of issue which i'm sure the weber doesn't have so if you cant fix it either live with it or put back the old carby or get used to stalling it as you turn off the key ..

Just had another thought in that back in the 80's the falcons they also had a idle solenoid set up to stop dieseling & you could rig something like that up in that when the solenoid is energised it will crack open the throttle so it idles at 800 or so RPM & when you turn off the key at the same time it will lose power to the solenoid & so basically shuts the carby butterfly to nearly a zero opening which should work out ok as far as the dieseling situation goes ..

Also late as in 1979/1980 ford escorts used a anti dieseling solenoid, particularly 1.6l model. Usually mounted on top of inner guard. Just t-piece hose into pcv line and connect ignition 12v. Turn ignition on shuts valve, turn off opens valve and gives engine gut full of air.
Unluckily don't have photos anymore, ex wife destroyed all car photos without telling, me soon as we were married.

I forgot about the escort ones & how they worked, some of them used to run on like a ****, trying to think if they had the solenoid valves on them at the time ? the carby fuel dieseling solenoid is certainly the best of the lot but not able to retrofitted though ..

Jeez I can understand how she's an Ex wife, you must have thought at the time shit what have I got myself into seeing her do that sort of stuff without even asking you ..

Some of the later KE Corollas has anti-dieselling solenoids fitted to them, the Aisan carby is probably similar to the 22R one as well (just smaller)

The Falcons had a solenoid valve which cut the fuel supply to the idle jet thus stopping run on. But if you had the idle set too fast it would suck fuel from the main jet and this was enough for the motor to run on when turned off.

Thanks all for your replys and comments, I have ordered a 32/36 Weber idle solenoid which I hope will fix the issue, will post back results once its installed.
Thanks for your time and effort all.
