    Default Quick Fuel Race Q 750

    Hey lads.

    Can anyone point in the right direction with correct part numbers to suit a QFT RQ-750.

    Im after fuel bowl gaskets and metering block gaskets...the blue non stick ones.

    Ive had a look but cant determine what the correct ones are and im not going to take a punt on the pictures alone.

    Theres no parts list in my carby box either.

    Any help would be great.
    cheers

    Ring Quickfuel Australia.
    Most 4150 models all use the same gaskets you require.
    My local Autobarn keeps them in stock.

    I didnt even realise there was QFT Australia. Ill check it out.
    As for autobarn.... down my way they dont even sell jets let alone carby gaskets.
    not enough supply and demand down here in port macquarie. I miss the convenience of local speed shops in brisbane where you can walk in and grab what u need off the shelf.

    I know there’s a difference with the float bowl gasket as I had to trim a holley
    one under the fuel jet section to fit the QFT blocks but there wasn’t any notable
    difference on the block to carb body side I think the PN to check for the 2 circuit
    blocks is Q8-205

    Just received an email from QFT Australia.

    Bowl gaskets are #8-134

    Metering block gaskets are #8-139

    Full gasket kit 2 bowl, 2 metering block and 8 nylon o rings for bolts #8-205.

    And for shits n giggles i spoke to my local Autobarn and they havent stocked any form of carby parts for over 3yrs...but they can special order in from rocket.

    Gaskets on their way. Thanks guys.

    Whilst on the topic of carbs.

    I have a #6 PV in there at the moment from new.
    When i hit the pedal at about 1/2 to 3/4 throttle i get plooms of smoke (not blue smoke).
    When my mtxl wideband was working it would show a rich afr when the above would happen.

    288 cam, idles at 1200 in N and 1000 in D.
    Vacuum was around 10hg if i remember rightly.

    Would i be on the right track of decreasing the size of the PV? If so would i drop to a 5.5 or 5?
    Or any other suggestions would be good
    Cheers

    The PV number doesn't really have anything to do with the amount of fuel added, but the time or condition of when the fuel is added, as in as you open the throttle and the manifold vacuum drops below 6"Hg (in this case 6"Hg due to your #6 PV) the PV will open adding enrichment. Its the size of the restrictions behind the PV that are a main jet bypass that govern the amount of enrichment that will be achieved while the PV is open.

    Could the black smoke be the accelerator pump rather than the PV, the amount of time it has the cloud of smoke after the throttle is mashed will indicate if it is acc pump or PV related.

    Its only a short duration maybe about 50m or so and not continuous through the rev range.....well not that i can see anyway
    I think i have some smaller squirters somewhere.

    It used to do same thing when i ran my old 750 demon too....
    The squiters are the same size in both carbs.

    Did you get a tech sheet with the carb, stating PVCR and IFR sizes?

    As Mick alluded to, a short puff will be squirters, a long one is pvcr size.

    What size squirters now?

    The tech sheet only has main jet, hsab, iab sizes.
    Squirters are 31s i think...untouched from new.

    Primary float is half way on sight glass, secondaries may be a fraction over. Ill tweak them a little lower.

    Halfway is probably too high, drop to 30-40%.

    No worries, ill lower the float level and see how that goes but i think it will make a difference?
