I picked it up today, and mowed for about 25 minutes, the machine bogged down while on a SLIGHT incline, then turned off. Wont start again. Now its back in the shop. My question is. Do injector pumps work half azzed? I always thought they either work or they dont. The fuel lines were cleaned when injectors were done. Im kinda pissed off that I paid $680 for injectors and I am back where I started. Any ideas? Air filter is clean, and compression is it must not be getting fuel right? Help! Im going nuts.

Coupla thoughts: 1. NEVER use ether, on asian diesels. The piston tops are just too thin, to take the knock.

2. The # 1 problem I have seen, in years of experience, is the wrong fuel. gas mixed with diesel, water mixed with fuel, clogged diesel filters, too much Diesel 911 ( alcohol fuel drier) mixed with diesel. Go back to basics, if it isn't getting enough fuel, at the right time, check to see if it is getting too much, like a bleed off line back to the tank clogged, of crimped, if it has one.

3. As the dealer has repaired it once, he should fix his mistake!
