Fuel Starvation or something else ?
Posted: 10 May 2017 17:03
Hi All,
I'm having a persistent problem with my 95 4.2 SGL.
Most of the time she runs fine and is even "pretty nippy" (both Graham Cumming and Peter Connan have driven her about 9 months ago) but come to a long uphill, more than a kilometer or so and she starts jerking and spluttering and losing power as though I'm running out of petrol. The odo is currently on 192000km
So far I have:
1. Had the carb stripped, cleaned and reset by Carburetor Ace, a reputable guy here in Durban.
2. Replaced all the flexible fuel hoses (in case they had perished and were drawing in air while not showing any obvious leak)
3. Replaced the fuel pump.
4.Removed and cleaned the fuel tank. The internal strainer was partially blocked and has now been removed. I have 2 in line filters fitted, one near the tank and 1 up front near the carb.
5. Plug leads and spark plugs have been replaced.
6. Coil replaced with a Bosch blue coil. I'm using the Pertronix Ignitor 1762LSCC electronic ignition from Offshore Marine. On their advice the ballast resistor has been bypassed.
Any suggestions for next steps will be greatly appreciated.
Mike
