13 clone

I have my harbor freight 13 horse engine in. I am having trouble with shifting from for to rev. I have it set up for key start. I can't idle my engine down slow enough to keep the clutch from closing up. Anybody else have the same problem????

Yes..it is commonplace. It doesn't occur when you use the pedal to start and stop the engine entirely..there are a few ways to go around it, like try idling it really low, and shifting right on the cusp, etc..
I just shut mine down..and sometimes if I really want it to, I can idle it low enough to shift, there are clutches that enable that also.. I think Tom has the CV tech clutch that will go around the tension the running engine
places on the tranny..by using a roller bearing in the center.

use a snow mobile clutch, i had my snow mobile engie that was a twin, i am using that lcutch for my swap because it revs a little higher before engaging, but stil engages fairly low

I had the same problem on my 16hp. But I finally got it tuned where it will idle down, you just have to wait for it. But I have the CV Tech clutch and had to use a soft spring to get it to release at the lowest rpm It will idle at. But if I am haveing trouble I just shut it off and shift and restart. It'll come together.

my red spring clutch doesn't come in till1800,no problem.I have a HF 13 with a rev kit,the thing has a ton of torque,went on the CAW ride this weekend & climbed anything I tried.It seems like it's slow to rev but not a problem,I watched the tach & never ran over 2500 on the trails.I just have to get disc brakes.hookm
