    My kit came with a "screw tool" but there didn't seem to be any instructions on what to do with it. I got my motor installed and apparently didn't need it.

    Used for pulling drive sprocket, large clutch gear (tool is reversible), Make sure that the tool is bottomed out and secure, or it might (usually a problem) pull the threads either in the gear or tool. The tool is screwed into place then the center installed. As the center bolt/shaft is tightened and under pressure tap head with a hammer...continue, repeating procedure.
    Tool used if engine needs to be taken apart.

    One would think that Mr. Grubee would have sold enough of these $25.00 engines for $150.00 or $200.00 by now that he could afford to pay someone to write a comprehensive assembly and maintainance manual instead of the joke that comes with them now.

    nope...works the same, but it's the wrong size for crank arms.

    I do agree theres a huge need for a clear assembly manual , I've yet to see a novice do a good build using the supplied instructions .

    I should have taken some pics of the worst built attempts as a learning tool , seems the translation from Chinese to English manuel's are horrendous , when looking at many installs I felt like screaming , laughing & crying ~ Haaaaaaaaa'''

    and if you thought pushbikes were hard, try stepper motors and driver boards that need to be hooked up to a PC.... :sweatdrop:

    Stop digging up threads!! Look at the last date somebody replied. This one was last responded to 6 years ago!

    Nobody needs these old threads dug up when it's mostly common knowledge amongst the users what these things are.

    This is why you look through the forums with the search tool. This stops people from needing to create threads or responding to threads that don't need answering.

    Unless you are responding to a thread that sparks interest if results weren't known or answered (the primary use of a forum, to collect information) or wanting to add additional info to a little fed subject, believing it will help others with problems they may come across.

    I mean think about it, if they haven't figured out what the thing was after 6 years there's a good chance they don't do bikes anymore.

    Hey Franenstein, who are you? A cop? :)

    Yes, all the early respondents have expired, except HeadSmess, he seems to be well preserved.

    No you're right, we should start replying to dead, useless threads right away.

    Glad you could see it that way, so easily.
    A lesser man would be defensive, maybe even derisive of a veiwpoint he couldn't understand.

    So, instead of opening up a new thread for age old issues, these people have researched the old threads looking for answers.
    Maybe we need to do more of this instead of constantly opening repetitive new threads?

    Now, I don't mean to be critical, but I'd suggest we avoid the dead and useless threads if we can.
    I'd suggest we stick to relevant issues like squish and porting and chain types and the like.
    Less threads, blending old opinions with new, not so bad...
