I think this thread might not be dead yet..........
It's a long story but we finally got the Petteroid running this morning. Last August, about the time of the last post on this thread, we got tired of waiting for it to behave itself and got a Metro 6/1 from Sam Crosby. (and also 6 more in case folks around here want one) It was put in service (we didn't take it apart, check for sand, etc)and has been running 10 hours a day 5 days a week ever since, without any trouble at all, besides having to replace a gib key. We should've gotten the Metro first and never gotten the Petteroid at all.............
After that we contacted Ashmawegh to try and get parts, (injector, injector pump) they weren't interested in selling only parts, and they did their darndest to sell us a containerload of their JUNK er, I mean engines, before the EPA regs took effect. This was over the space of 2 or 3 months and who knows how many emails.
Then last week we took the part numbers of the pump and checked with Power Anand, and lo and behold they sent us parts and it fixed most of the problem. The injector is now firing properly on every stroke, except at very low speeds, (I assume that's normal) and we don't have the runaway problem any more. The only issue left so far is it tends to smoke, and we're running it under load now to see what happens.
In conclusion, we now have a Listeroid that we use practically all the time, works absolutely great, and now we also have a Petteroid that we put who knows how many hours of time, labor, frustration in to make it work........and now we don't need/want it. I think we'll probably sell the Petteroid if anyone will take it off our hands.........parts, cooling tank, accessories and all.......
