He wanted to see my sparkplug so when I got home I removed all eight and brought them Back to him which he examined and said they All looked good . He said he,s stumped he's never had this exact problem before.
So yesterday I went to a Local car show and was speaking with a gentleman that seemed pretty knowledgeable Made a suggestion I'm going to try as soon as my neighbors wake up.
He wanted me to check the baseplate butterflies on my primary if they are set totally closed it could cause a Air starvation When cruising off throttle. Which kind of make sense to me as if I give it the slightest amount of throttle the condition disappears. He said just to set them slightly cracked. Not sure how to do that Exactly than turning up the idle Screw slightly and adjusting the idol mixtures to get the RPMs correct?
Wish me luck  |
If its idling at 900 they are slightly cracked. Watch about raising the idle too high and exposing too much of the slot, you'll get the carb into the transition circuit prematurely and you'll get some bad results from that.
