Holley/Demon Carb stumble

skrews said

Have you gone through the carb. Demons carbs are notorious for their lack of QC. They always have machine swarf left in them. I used to be the guy that went through them at the engine shop I worked for. Every single new Demon had crap in it, not to mention the build and assembly problems. Had one come through that didn't have emulsion holes drilled in the rear metering block. Have also seen missing jets, air bleeds not drilled through, power valve channels not drilled, and numerous other problems.
You might see if you can borrow a known "good" carb from another racer.

First off Thanks for the link!!!!
This is a used carb that i rebuild several years ago.
Yes i have heard about the problem with Demon carbs including broken drill bit being left in them and still ship it.

The only real problem with this carb(until now) is that it has ford linkage and i had to drill a hole in it to get the throttle linkage to work.
Well last night that kick me right in the butt!! the faster accelerating squirter ramp hit my installed chry pin for the linkage.
couldn't get above high idle. Had to put a smaller nut and grind the foot to make clearance.

I my have to re rebuild the carb. some crap may have got down one of the bleeds or some dumb thing like that.
I do have a good carb for it but it is only a 600 DP that worked just fine before the demon.

I have two week to figure this thing out before the next race. works been crazy and last night was the first time i have had to work on it.
Thanks again! I will be ordering them jets and i might as well order a rebuild kit for it as well.
