I have a 1997 Challenger 1800. I brought this down to Tampa over my winter months in Cleveland Ohio and to make a long story short i replaced both engines, carbs rebuilt and new bearings on the pumps. My mechanic took it out and said it ran perfect. When i took it out the driver side engine kept shutting down at 4500 rpms. I checked the compression on both engines and they were as follows RH engine mag-0 and PTO-110 the LH engine mag-130 and PTO-118. The spark plugs on the RH engine were extremely dry and looks like the engine was running without oil. Possible oil pump failure??? Since i am in clevelnd and my warranty on my engines is in the Tampa area from "Jet Ski Masters" I am confused at what is wrong and why something like this could happen. To me it seems the compression is low and Jet ski Masters is telling since the New/Rebuild engines were bored out this would have an effect on the engine compression and as long as the conmpression is over 100 i am fine??? Any Advise would help. My wife and kids are driving back down to tampa in the next couple of week if i need to have her take anything down there she can and get my warranty parts.
