i bought a coot someone converted with 24 hp honda in rear.
the prob is trans turns slowly low rpm.belt seems rihgt size.
i can take something and push against clutch on trans so will not try to
turn. was thinking maybe some type of small disc brake to put on end of clutch
to hold to stop while shifting ???
anyone else encountered this prob dont wont to grind gears.
thanks !!
Hi HomerCoot, welcome to the board, its funny just from reading your thread title I had a feeling you where talking about a coot. I recently just purchased my first coot and know what problem you’re talking about. One of the problems (or I should say things to watch out for when modifying a coot) is if the ideal speed / RPM is too high it will be impossible to shift gears smoothly, if at all. The best way of course to remedy this is by lowering the ideal speed to a point where the gears in the transmission turn slowly enough to engage. The 2nd thing you can look at is the centrifugal clutch. This will fix the issue regardless of ideal speed. By increasing the tension on the clutch spring (the coil spring found around the output shaft in the clutch with either a stiffer spring (I know on my Comet clutch you could buy different stiffness which were rated by color coding) Alternatively and cheaper, just slice some pipe up with an ID that fits the shaft and an OD that fits inside the clutch. Use these spacers to add compression to the stock spring. This in turn will mean the engine will have to spin at higher RPM before the clutch closes. When set up properly the clutch won’t engage at all at ideal, even with a very high ideal. Thus you can change gears easily whenever you let off the gas.
I’d like to see pictures of this monster rear engine coot that is quite a lot of HP! You probably don’t even need Low range lol.
