Same here...but #8 along with #2. Changed the plugs from autolite 3923's to stock range (NGK's) and it runs a lot better! But... still misses a tad every now and then on cold start up.

whats the part # for the NGKs I been using the autolite 3923 but I get a misfire like every 2 to 3 months I change plugs to new ones and it'll be ok for another couple moths I want to try something different.
Did you finish polishing your frame?
