Hi Guys, I thought I'd run this one by you.
I purchased a Ram 1000 from a guy in January. He said it was in " perfect running condition". I received it around Jan. 15th, looked it over , it spun free, starter spun it free, so I put it aside until I needed it. For the record, it was winter here untill about 3 weeks ago. On April 12th, I took it out of the box, hooked it up and attemped to start it. ( I have another Ram 1000) Would not fire all afternoon, all settings tried, finally started it from the back with a lighter. Engine lit on propane, ramped up, switched to kero. and shot flames , then shut down on overtemp. Upon cool down it was rubbing somewhere, and seized up, stalling the starter motor. I emailed the guy, and he said he's not responsible because I did something to it in the 3 1/2 months I owned it. I sent it to Carlos, and it needed a combustion chamber, bearings, bearing support, fuel manifold, hardware package ect. I never touched it until April 12, but the guy insists I either crashed it, or did something to it, and won't be responsible for anything. In fact, now he says I'm trying to scam him. I would like him to pay for 1/2 the repairs, and feel that's more than fair. He refuses.
Do you think I'm out of line ? I guess I should have started it right away, but I trusted him, and didn't. He assured me it was test run, and in perfect condition.
It couldn't have run in this condition, and Carlos assured me it was nothing I did. It had worn out parts and improper maintenance/ assembly.
What are your thoughts ? Am I unreasonable because of the time lag ? And please, don't tell me to buy a Jetcat ect.
Thanks,
Dale
