    Nice work and paint feathering, if you need to repair any more crack's etc,
    try to get rid of all the paint near the join's, and 10mm either side, the abs wont stick properly to painted surface's.

    I've also found that the joining tends to be a bit uneven, even after sanding. So I went to supercheap auto and bought a tube of plastic filler. It's like clay you mould it together and spread it over the surface. Sands back real smooth, lot easier to work with than bog and much faster curing.

    Plastibond or 2K bog for car bumper's is good for levelling plastic's, the 2K stuff sand's back easy and is really fine stuff compared to normal bog
    or just build the plastic up higher than needed so when you sand it back it become's level with the surrounding plastic

    Prepsol or wax and grease remover if you can get it.

    Acetone is an ABS bonding agent, you can melt down ABS piece's with it to use for repair's etc, take's around a day to get to full strength
    I normally use a decent single edged razor blade and carefully push it under the sticker, then use eucalyptus oil, thinner's or degreaser to get the remaining sticky stuff off.
    A Caramel wheel is also good, pretty quick but more expensive way to do it

    Look's like all the float's are set too low then, these are the 3LN1 carby's aren't they ?

    Did you turn the ignition on and off a few time's till the fuel pump cut's off straight away, the fuel bowl's wont fill if you just turned the ignition on once
    I think you'll find the fuel height will rise up a fair bit if the float's are set to 14.7mm ish

    With the float's at that high height, it would take a bit longer than normal to fill the bowl's, the fuel level would be about 13mm or 14mm above the line, verging on coming out the overflow

    Yeah just use a flat head screwdriver to bend your tab's toward's the carby body, they won't need a lot, about .5mm

    You keep mentioning Zeal carby's ?
    How come you are posting pic's in this thread ? You've confused me

    sorry I haven't posted for a while just been crazy busy. Not much has happened on the cosmetic side but decide to take the bike to a local mechanic to set the carbs up. bad news is the compression is low across all cylinders 100 99 90 89psi. so may need a rebuild.

    Just be a little wary of a mechanics opinion .... most wouldnt know an old carby bike if they fell over one , especially an inline 4 ..... so a second opinion would be advised

    And ask him how he did the compression test

    Have you actually had the bike running yet? I've sort of lost track a bit.

    Even with low compression if you can get the motor spinning fast enough it could still run so if you are sure the carbies are set right I'd be giving it a decent hill/push start. Maybe once it bites you'll have less of an issue.

    If you get stuck the engines aren't that hard to rebuild, just time consuming.
