Pedal starting the HF 99cc Predator

[chainmaker]

Car crafter, how have you done with your clutch, I am also on the hunt for a one way bearing clutch. I tried calling max torque yesterday with no answer. There was some info on here with a mod. That was operated by levers like a compression release to allow pedal starting of a max torque clutch can't find it now.

I'm enjoying he max torque but want to try other options. I'd love to see a mod so I could leave the clutch and pedal start

There is a clutch in the works it should be available in a few weeks. It is a lever or operated clutch which should help a lot of us out.

Who is making it? Is it a real couple of weeks or is it the standard manufacturer couple weeks (IE: 6 months - never gonna happen cause it was placed on a shelf and forgotten)?

Sorry I posted that pic and forgot to include the link. You tube videos.

Cool, looks like they are shooting for the $100 - $125 price range. Not too much more than a good centrifugal clutch, and if it really helps with acceleration as much as they say, it sounds like a good deal for use with 79/99cc HF motor.

They are starting with the 3/4" shaft version, though, so you would need a shim to work with the 5/8" shaft on the smaller Preddys...

Is there any way to make a manual clutch work on a HS 49cc? No mean to thread jack

Sure, there's a way to make one work. How do you plan to make one? A idler-pulley is one way. I don't know about a commercially available pre-made one.

I'm kinda likeing the max torque clutch so far. Thanks to the pz22 carb the predator fires with a quick and easy pull first time every time.

I originally wanted pedal start because of cool factor and didnt like how the predator had to sometimes be cranked 3-5 times and always with the choke (due to the EPA carb). I think I'll keep it this way after all.

you get more performace fron that carb?

 

[young grease monkey]

once the EPA gets involved, everything is sacrificed for emissions. i had an idea for a belt drive cvt that is manually operated instead being controlled by rpm. it would use a regular drive pulley and a constant tension driven pulley. the constant tension pulley uses a spring to pull two halves of the v pulley together, so when you tighten the belt it moves the belt closer to the center and lowers the mechanical advantage (think going into a higher gear). this would allow for pedal starting

carcrafter22: tell me about this pz22 carb. Specifically the jet inside. You just run it how it arrived or diddle with the jet?
