    sounds like you have more than one thing going on .but i would do what i said plug the 750 power valves off and move up 5 jets sizes were you are now and try that. air bleeds should not be that far off ? but they maybe junk in them like i said you will have to do some of the things to find out

    hey pat,
    Do you mean up 5 jets from stock jetting? The air bleeds checked out fine, so im thinking to rule that out.
    When i was just running it too, i had a 2.5 power valve in there and it seemed to run pretty good with those lower jets except still the VERY strong gas smells which has been the problem anyways. and the white smoke scares me.
    thanx for the help and ill try the blocking off once i hear back from ya.

    yes go up five jets from stock if 750 i think they may be 72 ? or so 77-78 try that you want to dry it up and block the power valve up front and back if you have one you want two start with a base line and work up from there

    one other question on this. The 770 i have is a vacuum secondary carb and was wondering how that works since the power valve is already blocked off and if it really would matter on jet sizes for the secondaries. Also, would it be better to use the vacuum secondary carb for this?

    thanx and sorry for taking so long to resond.Was on vacation for bit.

    thanx again
