I am about to give up and put a match to my first 4x4.... or can somone point me in the right direction OR SELL me a EFI Conversion...
Please explain the playing up and running like shit. Please provide pics, so we can see which carby you have.
I would advise to replace the fuel filter, and purchase a motorbike fuel filter. Install this between fuel pump and carby.
Check air filter, what condition is it in?
Carbies aren't just shit, if they have been rebuilt properly.
This info is for the stock aisin carb.
Download the factory service manual and restore the carby to factory settings. Checking each bit etc, as best you can.
If you are careful, you can pull the carby apart and use a bit of carby cleaner and an air compressor and give it a good clean (carby cleaner and blast the tiny little holes). Remember stock primary jet is 85, stock secondary is 105, these are located in the fuel bowl). The primary jet (#85) is used for the smaller diam bore (if these are wrong the car will run like crap, rich at partial throttle, and very lean at WOT).
After rebuild or carby and reinstallation, check that you have no air locks in your cooling system. Check FSM to make sure all your hoses go the correct spot.
Inspect all the rubber vacuum hoses.
When the car is running, spray small amounts of crc, aero start or carby cleaner, around the carby and hoses etc, looking for an air leak. If leak is found, replace hose.
When the car is warm, ensure choke is off.
Set idle to 850 rpm, check timing, check mixture screw (if its been fiddled with). set idle to 850, check mixture screw.
Allow to cool down, and set cold idle.
I would advise against using webbers - (sure some people love them, like some people love other *** things)
IMO
Stock carby is fine
EFI, anywhere inbetween is $ spent on something delaying EFI.
