    Wipe the belt and pulleys clean and dry. Rub baby powder on the sides of the belt, that will make it hook up smooth. This worked great for my belt drive mini dozer!

    Sounds like some of the welds could of broke loose on the engine plate.

    I have a flywheel that I'm certain is out of balance. I had it on two different engines, and my bike wants to rattle to pieces at certain RPMs.

    Believe it or don't, I've taken it to 3 machine shops trying to get it balanced.
    All 3 said the same thing, "I don't have a mandrel that'll fit it."

    To which I replied to all three, "Hey, I got an idea, let's call a real machine shop!!!"

    I've noticed the same thing on a buddy's single-speed DB-P212. I think it could be a few things:
    Added stroke and bore over the Honda 196 may add some shakes.
    Carb not made to pull a load through low-mid rev range.
    Balance factor, also not suited for low-revs, high-load.
    Light duty engine plate and chassis may be transmitting more, normal movement.

    I was discussing the odd light-crank, heavy-flywheel setup with interweb pals recently too. Great for an engine that may strike an object while mowing, so the f/w can maintain momentum by key shearing, but not what the typical high-rev hotrod desires. I'm hoping to adapt a motorcycle-type full-circle crank and run a 3.5" sub-1lb f/w with a curved CDI and lighting coil. Maybe even chain-drive the cam so the engine can run "backward". leaning forward, eliminating the fan and shroud for free-breeze. Honda G400 ran cam by chain, as do a quadrillion other varieties of engine outside the ditch-pump world.

    Umm, may sound silly but any chance the bell on the clutch is slightly bent/dinged/deformed?
    Would explain teeth rattling low rpm shake. Clutch shoes riding back and forth over a high spot on the bell.
    Once it is able to lock up, problem would disappear.

    You say you used that pmr adjustable plate ..Try c-clamping the frame and the pmr plates together on back and front test if tight or helps...Never heard of anyone having to run bolts all the way thru both the adjuster plate and frames plate basically using it as a riser instead of its intended purpose..unclear if it is magnifying low rpm "chatter" on take off....I'm thinking out loud..my last resort thought...

    Not silly at all. Step 1 in the troubleshooting process here should be the clutch.

    250 pounds is alot weight to run through stock OEM clutch. i would chatter too if i had to push that much weight when taking off. i have also heard of that same problem with the stock 2.5/2.8hp doodlebug bikes and seen guys replace the stock clutch's with a max clutch with just a slightly higher stall clutch. not saying this will fix your problem with your clone/honda motor.
    i got couple stock doodlebugs for the kids to ride and they chatter bad when taking off with me on it(#175). but with the kids on it....not so bad. just no weight for the clutch to fight with when a #80-#100 kid on it.
    you did say something about replacing the clutch soon. interesting to see what happens?

    torque converter would be better...... it's just more money$$$
    goodluck.......

    Borrow a different clutch before taking yours apart
