Off Idle Hesitation

Sounds like you had it tuned good for the 40 degree warmer weather and now the cold stuff's making it lean. Had the same thing happen to my Cuda. Back in Sept. I bought a 750 DP and rebuilt it and only had to do minor tuning to get it running great. No hesitation then. Drove it last week when it was in the 40's and man did it hesitate bad.

Joe if you need a 31 or any other squirter let me know. I have a bunch and can stick one in a mailer and send it to you.

You're right and yes I did. I was thinking a megaquirt fuel injection system on the home, lol! I really didn't expect to be driving the RC this winter so I got caught off guard. I'd like to try that 31 if you don't mind. If it doesn't work I'll send back or send you the 28 in return plus a few bucks. I had a whole selection from back in the '80 and sold them off before I moved to colorado. I didn't know it would cost $120 to replace them future, lol.

I agree, try a larger squirter...it should help things...if it dosent work, at least it was not a lot of money to try it.

Agreed! :cheers:

ram, I meant have it all in earlier rather than later... Like centrifical all in by 1800-2K if it doesnt detonate. You can also adjust the power valve level to come in earlier or later by higher of lower rating. That might be the best way, because the load automatically determines if it gets morefuel.

Yes, I knew what you meant. :) And yes, that makes total sense. Now, if I can only find that dam light......lol.

I'm running a 6.5 power valve. I need to run a line from my vacuum gauge in the cab to the manifold to get a good baseline.

The 72 primaries and 78 secondaries (no secondary power valve) seem lean now too at WFO. I may bump up to 74s and 80s after I get the off idle problem resolved. There goes any semblence of fuel mileage.
