Thanks guys, finding time to solve issues has been a challenge.
I hope to be able to fine tune both timing and carb now.

Well got home and fired up the cuda. Neighbours weren't too happy but it was only 930, late but not drastic lol. Fired up and immediately went to 2000 rpm. let it warm up sprayed carb cleaner around base looking for vac leak. Couldnt find one. Dialed in idle screws while.running to stall engine but wouldnt stall out lol
Removed idle screws sprayed with wd40 and carb cleaner amd a quick blast of air. Snugged screws in then out 1 1/2 turns.
Fired right up, lowered idle to around 850 and runs good.
A quick set of timing to 15* and then out for a rip.
Still need to tweak but WAY better. Its drivable lol
Thanks all!
Yep, when I told Lori last night I was going out to work on it, she looked at clock and rolled her eyes lol
Had the back neighbor pissed as he went and grabbed his big spotlight and shone it my way. Shoulda shown him the Harvest Moon.
When I dialed in the mixture screws snug I waited about 2 minutes and it wouldnt stall lol. I guess quite a bit of junk in there.
About a 15 minute job total with setting initial timing. Then out for 20 minute rip with no issues.
Of course I had to do a drive by of pissed off neighbors lol
Thanks again Greg
Is there a buddy that'll lend you known good carb for a trial?
No such luck Dar, Ill pull the top open tomorrow. Carb was new 4 years ago, but time for a look see.I bought these rods n jets earlier in the spring, a switch may be required?
Wish this happened in the spring. Winters coming, going down to -2 tonight.
Now see....you should have taken that job offer out here...then I could lend you a few carbs to try!!! ;-)
Seriously, I doubt a rod or jet change is going to fix your problem. While the carbs apart, blow every passage out with air, and check your float levels.
The surging seemed to stop after you did the first rev-up. Could it be that
the choke butterfly was just closed too far?
Steve....Every engine's different....they all want what they want: timing, carb, mixture, etc.. A creit card gap is a bit too closed. Try backing off the choke butterfly setting a bit on your next cold start and see if that helps.Not for what they want for property out there lol.
I should have some time friday to take a look at it. I thought choke too, but it had a credit card thick gap. I read thats proper gap?
Thanks.
When I check online for cfm formula, online they say max rpm (6000) x cid (273) ÷ 3456 = carb size. Which works out to approx 500 cfm?
If I do swap primary Greg, is #86 the part # ??
I will finish cleaning, reassemble tp stock specs, make adjustments (choke too) and post back.
Thanks guys! Much appreciated.
