Rather Strange problem. 4AGE + idle + tacho

[Deeken]

Hey guys, have sorted out the shit running/ignition problems I've had, but now realised my starter motor can't crank my engine strong enough to start.. Does anyone know of where I could get a high torque (1kW +) 4age starter motor, or any starter motors that are compatible/modifiable to run on the 4age/t50 set up I have..

Cheers.

hey man, ive got the same problem atm aswell hey. it seems to run ok when its like 30 degrees or so out, but any less than that and its shit.
ive been advised to check the TPS and yeah also cam timing aswell.
if its not your cam timing it could be the throttle position sensor, i havent had time to check my own out yet.
i just put my bigport into my 86, and all i did was use the old tachometer wire (i think its like black and brown or something) and put it on the negative of the coil. it seems to work ok for me. maybe make sure yours is connected properly?
let me know if you sort out why your car is running shit, i'll do the same haha.

Okay, dad figured out a huge but simple part we over looked. When we were setting our cam timing, we turned it over to TDC, but the thing is we were setting the opening of the intake cam properly etc etc, but then also setting the closing of the exhaust not even thinking that this was wrong hahaha. This was putting the opening of the exhaust way retarded in relation to the intake and probably why we were getting the ignition timing out so far.

But now, we have a new problem, after pulling the cam covers off today and resetting the intake opening to make sure, I then turned the engine over a full revolution to get the opening on the exhaust and set it up properly lol. Holy shit it made a bit of a difference to the compression whilst turning the engine over.


Has anyone used a standard 4ac starter motor to run a 4age? The starter can barely crank my engine.. (maybe 50rpm) but barely loses voltage... Could it be my starter motor being too worn out/pulling to much current, or the compression in a highcomp 4age be too much for a standard 4ac starter?

Looking into buying a new starter either way, as the old one sticks after the engine fires, would anyone have a high torque starter part number or know people selling high torque starters for 4ages??
