I am extremely pleased with how these plugs work
I had a choice between good performance on short drives, or good performance on longer drives, and
always bad performance in cold weather. After I installed a set of Pulstar
plugs, I put the stock idle feed restrictors back in and leaned out the
idle. Now, throttle response from a cold start is flawless and throttle
response remains so even when the engine is fully warmed up. As soon as the
snow melted, I went for a 90-minute drive in 30-degree weather covering all
conditions from country roads to freeways to city streets without a single
stumble. I went for another long drive on a recent 65-degree day with
perfect performance again. On both drives I found I was more likely to hit
the rev limiter in first and second gears so power may be up as well. To
summarize, I thought the only way to solve the drivability problems was to
replace the carburetor with a fuel injection system, but just installing
the Pulstar plugs was enough. I am extremely pleased with how these plugs
work.
