This 630b has been giving me problems. Sometimes it won't start or even fire. To get it going I have to open up the hose to the carb and put gas in manually. This most always works, then when it's warm and I have to turn off the machine, it will start up with normally no problems. It's the cold starts that kill me. Choking using the choke lever doesn't work. It works the butterfly in the carb, the flap that turns, just fine.
Also, sometimes when I put gas in manually I get it to fire and run for a few seconds, then it will die, but I fight it by using my hand to cover the carb opening. I disconnect the hose to the air cleaner and turn it straight up and this is where I pour the gas in.(about 2 table spoons) After engine fires and starts to run, then starts to die, I put my palm over the hose entrance and use it like a choke, except I can completely block all air creating more of a pull from the fuel line.
The other day I put in a new inline fuel filter. This idea was installed several years ago and when I did replace the old filter for the new one, the filter actually filled up to about 90% capacity. I can see this because the filter is not metal but see-through plastic. My other filters almost never filled beyond 50-60% capacity and normally running with about 10% fuel capacity inside filter. However, after about day 3 of using the grinder, it is running(filter) and sometimes has less than 3-4% and it's so low and can't believe the engine is still running.
I thought since because I can see no air leaks happening it could be the pump. When I have had air leaks in the gas line, I can see a wet dusty spot where it's at, but see no evidence of such a leak now. Is it possible to have a leak in the line or connection somewhere and see no wet dusty spot?
This problem goes back to last year, but not sure when. I can get a new fuel pump, but it will be an electric one and would also have to get a pressure regulator all for about 1/2 the price of a new Vermeer fuel pump. I can also rent a pressure tester for the pump to see if it's pumping at the correct level. Having me ask these questions now can help me diagnose and troubleshoot the problem(s) better.
What do you think the problem is?
Oh, almost forgot to add... when the grinder is finally started and is running, it runs fine. It has stopped while in the middle of doing a grind about 4-5 times in the last 45 days. Recently it did this twice in the last week. I think the last episode of engine cutting off was due to lack of fuel in the fuel filter and not getting enough gas.
