GC1705 Will not Start!

Alright. I got the tractor back from the dealership tonight. 33 degrees Fahrenheit here. I go out, run the plugs for 20 seconds, and try to start it--and it chugs for 8-9 seconds before finally firing. They are telling me from the dealership that is normal GC behavior. I still think it sounds like it can't get enough fuel or something when it is trying to start. They put in a new battery, checked glow plugs, new battery cables, checked compression, and all that. Maybe I am just expecting it to fire up too easy. I do realize it is a little colder right now than when I first started having issues, so maybe it will be better when it warms up outside.

That's not enough glow plug time.

I do two sets of 30 seconds. Fires right up.

Nice day out today, so I took my own advice and did some maintenance/inspection on the fuel lines. Replaced the c.3" line from the pump to the return line, inspected the resistor for blockage, and re-installed. Inspecting afterwards, there was fuel seeping from the 3-way connector. Went full throttle and had fuel spraying/misting out of the return line fitting. The line was very loose on the fitting. Cut 5/8" off the end and reconnected, leak gone. I am wondering if the pump was loosing prime, as the GC2300 was becoming hard to start after sitting for a few days, but has always started up immediately after use. Also blew some compressed air through the return line to tank, while the line was off, to ensure there was no blockage. Won't get to freezing here for a few days, let you know how things work out. The hard start has also been reported in 90F weather (atsah in FLA witth a GC1705), his issue was also the return line fitting/lines.

ps. 2 different clamps styles used on the fuel lines. Philips head, and Robertson #0 (square drive)

This is the best style fuel line clamps you can buy... They are rated to hold 60psi fuel injection pressures.... And recommended for all low side fuel injection pressures/draws....

Picked up an assortment from Amazon. When the weather gets warmer going to replace all the fuel line clamps. Bunch of maintenance to do. Replace coolant lines, clean all the engine electrical connectors. It's been a bear to start, glow plugs don't seem to be working, have replacements for them as well. Easiest way to start in the cold has been to use a hot air gun on low setting (100' extension cord) blowing into the intake manifold (removed the air filter) while cranking. Starts up like a champ.
