Went out again tonight. Tried to pay attention more to what the gun was doing. Temp was about 15 C and very damp, had rained a couple hours earlier.
Fired a couple shots off in semi first, everything works fine. Switched to auto and it fired about 2 or 3 nicely, then you can feel and hear it start to lose power. As this happens you can also notice a larger puff of propane coming out the bolt opening, and also out the end of the barrel. Within a matter of 4 or 5 shots, it powers out completely and wont even fire. Almost acts like it's out of propane. However, you can switch it back to semi-auto at this point and it will fire off the rest of the magazine.
Put in second magazine, and it fires sluggishly right from the start, and then after 8 or 10 shots it dumped the rest of the propane out the bolt. Third mag and then subsequent refills of the 3 all result in either sluggish, low powered firing, jamming, or dumping the gas out of the mag.
I don't know enough about these things, but it's like it's allowing too much of the propane to escape out the bolt opening, and not allowing the bolt to cycle quickly enough to shoot. I'm not sure if thats possible even?
Does anybody have any theories? Maybe things I can try to to help you narrow it down? This thing is getting so frustrating I might just run it over a few times and cut my losses.
Couple random questions. When the bolt cycles, should the plastic nozzle inside/part of the bolt stay wedged in the rubber by the hop-up for part of the travel, or should it freely pop out the second the bolt starts going back? Sometimes mine is tight enough it stays in briefly then snaps back, other times it all moves back as one piece.
And for filling these magazines using the small Coleman propane bottles, I have been holding it on until I can't hear gas flowing anymore, usually in the 15 second or more range. Any idea if these just may not work well to fill the magazines, maybe a BBQ style tank and hose would be better suited?
