Yale GP050:
Petrol / LPG supplied to carburator

Hi, I am looking for advice about my Yale GP050 forklift, its a 2001 model with the LPG impco 100 carburator on it.
I have just bought it from a liquidation sale and have got it running on the lpg gas. It takes maybe a minute of cranking first thing in the day but after it has been started and running it starts on the button and actually runs pretty smooth.
When renewing the lpg regulator I have noticed it has a petrol tank with a supply pipe for the petrol going into the carb via an inline filter and what looks like a pump attached onto the cylinder head where I am assuming in is being driven from, then between the pump and the carb there is a brass component which i dont know what function it serves (could it be a non return checkvalve or something??)
Anyway, the petrol tank is empty and I have never put any petrol into the machine.
My question is, should the petrol tank have petrol in it at all times so the engine can run on petrol if no gas is available and possibly for cold starts using petrol then switching over to lpg?
Is this carburator able to run on either petrol or lpg as both of these fuels appear to be plumbed into the carb? does this switchover happen automatically or has it to be done manually?

Many thanks,
William.

Hi there fish, thanks for clarifying the dual fuel setup.
I just was wanting to make sure that petrol was not needed for easier startup.
And yes I will stick with the lpg fuel.
As a matter of interest for yourself,
Model : GP050RGEUAE83.4
Serial no : A875B16288Y.

There is a guy in Scotland here that refurbished carburrettors/lpg and is well versed on the type that is on my lift, he said some parts might be an issue, but fingers crossed it's just needing a good clean out and tuned.

Thanks again for taking the time to answer.

Cheers,

William.

William,

Sorry, I failed to mention, the switch over for this lift is probably a mechanical switch. Newer lifts may have electrical switches. The tank does not need to have fuel in it unless you plan to use it.

The hard to do we do right away. The impossible just takes a little longer.
William,

Due to the age of the lift, the tank will need inspection to ensure no contamination gets into the fuel line. Makes sure the bottom of the tank does not have holes. If it was empty when you purchased the lift, could have had some problems in the system. Normally, when a lift has dual fuel option, one is hardly used. Unless you will have problems getting LP, I would not try to get the gasoline side working. If gas is cheaper, go for it. Need serial number to see what was installed. Good Luck.
