I have an '83 GSL w/ 72K mi. Have been making minor improvements to increase power i.e. exhaust, different air intake cover & K&N filter. After I changed the plugs, it seems that I lost most of my "second wind" from 4-6K.

Is this common??

dat not right.

I dunno... it's just a guess but perhaps the boots aren't fitting correctly on the plugs?

Did you gap the plugs? (Sorry, I couldn't resist. I once sent a know-it-all jr. technician to count the sparkplugs in a diesel engine, too. Funny thing is he actually went and tried)

Did the threads get damaged during a plug change? Might be compression leak, though that's rare. Are the wires all the way 'home' for best contact?

After initially driving it for a day, I did notice that the plugs were not tightened all the way. But even after re-tightening them, no power past 3K.

When I say no power, I mean no real power. It will still get there eventually. It's that there is no faux-turbo boost like before.

Plugs are pre-set at the factory, esp. those NGKs we all use in our rotaries. My guess is that the wires aren't pushed home. Or, horrible to contemplate, crossthreaded in. Maybe wires are crossed, but it's so easy to get them right you wouldn't think so.

Thanks for the input. Pretty sure they're not cross-threaded (I use the counter clockwise rotation first). It's pretty clean and alot of space to hand start these things. I love the rotary, lots of compartment space.

I think I'll attack this from a fuel supply standpoint. Maybe clogged filter coincidence. Doesn't look like anyone ever paid much attention to this carb.
