I have recently purchased a used 2006 Carby Cultus. Generally in good condition, 59K driven. The previous owner used the car on CNG, which was removed before i purchased.
Whenever i start the car in the morning, the car doesnot start on self and requires accelerator and secondly the car starts on 200 RPM and often the auto choke does not engage, so i have to press the accel to normalize or else it vibrates and shuts off. After the car stablizes at 1000 RPM, it has no driving issues, so the problem is with starting only. And very rarely lets say 1/10 times, the auto choke wud engage and i dont have to press the race to stabilise but race is often need to start atleast.
I need help to solve the problem.
new plugs, air filter, oil change, replaced clogged fuel filter, tuning (from a desi mechanic not with a computer), carb cleaned with (NASA) carb spray
Problem still persists, need help, i have two things in mind:
My mechanic says it requires carb service. Cost 2500 (inlcuding labor and carb repair kit) and 4 to 5 hrs time
Get computerized tuning and timing adjusted
I am not an expert my self, help appreciated. Does 1 or 2 above make sense, or do u recommend something else?
