Hey all,

the holley finally shat itself, So saturday was spent rebuilding the old thermoquad. Not a hard rebuilt at all, and I made sure EVERTYTHING was crystal clean before it went back together.

The motor has never idled as smooth... seriously, a 50c coin could ballance on this thing now

the only problem i'm having now is a massive flat spot on take off. The model is a 6-2146. The metering rods are adjusted as per instructions on http://www.thermoquads.com, and the flat spot got even bigger.

Basically what i'd like to know is, should the primary jets be increased in size to cure this flatspot? The reason I ask this is because under heavy acceleration, she lean fires, also under deacceleration theres a very faint pop pop pop from the exhaust that was never there with the holley.

I know everyone thinks that they're a bitch to set up, but there has to be someone on here that doesn't have the "piss it off and put a holley on it" answer for me

anyone??

If you are in Perth - AJM Carburettors in O'Connor. Flat spot cured for sure.

I don't have much for ya mate howeva do a few checks like wif a vac gauge just incase u hav a leak somewhere, I've heard of those plastic bowls warping over time! another thing check ur fuel pressure just to make sure and after those 2 a rite just pay someone 25bucks to put the gas analyser on it and give the mixtures a tweek. if u rebuilt it I assume the accel pump is ok howeva were u careful with that plastic fuel line in the carb that feeds the accel pump circuit, was it on tight and not kinked when assembled? hopefully that gives u something to do.

Thanks Ziggy, Yeah i made sure that little plastic hose was all cool. Theres no leaks anywhere, we've checked all that. I'm pretty positive now that its something to do with the metering rods/jets being the wrong size. I guess i'll have to keep hunting around the interweb and see what I can find
