Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

does it idle at all ?

Customer: replied 9 days ago.
For 2 seconds
Expert:  shawn patrick replied 9 days ago.

if you spray fuel in the carb does it stay running?

Customer: replied 9 days ago.
Not fast enough on my part
Customer: replied 9 days ago.
It dies before I can do it
Expert:  shawn patrick replied 9 days ago.

try keeping a gas soaked rag near and try that, we have to rule out a fuel issue problem, sounds to me though if it is running for 2 sec it just needs more fuel and to investigate the carb, is the carb new?

Customer: replied 9 days ago.
Old carb
Expert:  shawn patrick replied 9 days ago.

I would take that off and do a clean out and inspection of debris, they get junk in them clogging up the high and low ports, if you have compressed air use that with carb cleaner to get everything out, have you rebuilt a carb like this before?

Customer: replied 9 days ago.
I have
Expert:  shawn patrick replied 9 days ago.

ok good so you know the routine, let me know if that fixes it

Customer: replied 9 days ago.
I will do it
Could it be the line coming from the cylinder to the carb
Expert:  shawn patrick replied 9 days ago.

What line are you talking about?

Customer: replied 9 days ago.
Impulse hose
Expert:  shawn patrick replied 9 days ago.

Yes they crack very easily and should be inspected as well as the fuel line and filter.
