Re: New Member trying to get 3 712's running better

Thanks for all the help. You're going to be pissed when you learn what the culprit was. It was a fuse. The cutoff solenoids weren't opening. I had pulled the wires from them a while ago and noticed no difference, but wasn't sure what they did. Now I know, and one of the Managers, Steve, who was driv...

Re: New Member trying to get 3 712's running better

Thanks Undysworld. Replaced the filter yesterday - the cross ref number on the list is a steel body version, but Napa had the clear version. The one in place had dual nipples on each end - 5mm and 7mm, which is better. It was diff to get the 5mm hose on the 7mm nipple on the discharge end, but it se...

New Member trying to get 3 712's running better

I'm not sure how I got here, but I'm now knee deep in it. 3 Pinz 712's being used by a zip line company to bring customers up the mountain. 1 runs fine, one wouldn't idle properly, and one had a blown spark plug and carb issue (M6 screws holding the lower to the upper stripped, which I've read is co...
