Proform 850 dialing it in closer

Demonx2 said

That's a great video - thx for posting!! It is very helpful to me (and hopefully to others too) and is basically where I'm headed. I noted that when I put a smaller shooter on the front (31), which would have made the pump shot longer, things got better but not great (it has the pink cam for the reasons you state). I think I'll get some videos of mine to help - I wasn't smart enough to think of doing that!

Anyhow, I don't want to hijack your thread so I'll keep watching as you dial yours in and learn from it. Meanwhile, I'll go get back to work on mine. Thx!!

Well i finally took your advice!!!
The proform came with 33 squirters, and i went to 35s with little help.
Been racing all this time, having too roll.... into the throttle to keep it from launch... then bog.
Dug up a pair of 28s and threw them in before the race yesterday.
I can now WHACK the throttle and not fall on it face. who new!!!!!!! :thankyou:

Well just thought i would put a Period on this thread.
Always figured it was just to big of a carb and i would just have to feather the throttle out of the hole. or maybe put a 50 cc pump on it but just couldn't make up my mind as to which side needed it(primary or secondary) so i never got one.
NOPE! THE SQUIRTERS WAS TO BIG, "NOT" THE CARB!!!!!:thumbsup:
Final Note: The adjusted altitude was 9400 foot yesterday.(track is a 6600 foot) good air for us is 7500 foot. I tell you this because my 60' time was with in a couple .0x of my best 60' times with this carb!
