update....
We installed the new module from petronix...car started and, ran great, revved up by itself, and shut off after 5 seconds....Got some clean gas and tried it again...ran a bit longer, but rough..still shut off pretty quick. Noticed the advance setting on the distributor was set to 20 degrees?...is that normal for a petronix ignition on a TR4 engine? Engine will start...runs rough...like its missing on a cylinder ... got warm pretty quick...but wont run for more than about 10-20 seconds and then shuts off again. Im wondering if the gas that sat in the bowls has fubar'd the carbs because of the Ethanol added. pulled the plugs, checked the gaps, and cleaned them..They were a bit black...looks like its running a bit rich, but they all looked pretty much the same. What octane is recommended for a tr4 engine? we are using 89 octane w/10% ethanol. Should we switch to premium 93? should we add some lead substitute? Supposedly, the mechanic that rebuilt the ZS carbs used a kit that is ethanol freindly...but im starting to wonder. And the head was redone with hardened valve seats as well.
Motor rebuild and install into the frame cost us almost 7grand...so Im a bit upset at the moment.
