The 6100 accelerator pedal is no more than an inch from the floor. Since I have not found the measurement for the distance from the floor to the bottom of the accelerator pedal, I would like to raise the accelerator pedal in the 6100 to the height as in the 3600. The factory assembly manual states the carburetor rod assembly P/N(3696702)is supposed to be the same lenth for both models. But the 6100 carburetor rod assembly is one inch longer than the one on the 3600(10 1/4 inches). I have not measured both accelerator rods yet. But again the manual states they are the same P/N(3701623). Also, the spring in both are different. Does anyone know what the correct spring tension and spring length should be? Again, the manual state P/N 3695705 but no additional information. As always, everyones help and expertise is greatly appreciated. | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | If you are comfortable with the way the 3600 feels just measure and convert the 6100 to the same dimentions. Most FLAPS will have an assortment of accelerator springs, just find the one that fits your style of driving. JMO

If a spacer or thickness of gasket under the carb. has been changed at one time it throws the carb linkage off.

Cutting the rod and threading it and putting in a turnbuckle makes a nice adjustable rod or cutting the end threading it and putting on a clevis works too. | | | | | Joined: Feb 2007 Posts: 385 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2007 Posts: 385 | Jeez, crenwelge, I thought I had an original idea, and now I see that you've already figured out the turnbuckle. Waaaaaaah!

Buy a screen door tensioner, and modify the ends of it to make an adjustable throttle rod.

Jerry Are you sure one is left hand thread? I thought they were both right hand thread so that if you look at either end of the turnbuckle, turning counter-clockwise (widdershins) the rod would be pulled into the turnbuckle?

Turning the buckle one way lengthens, the other way shortens. Otherwise, the buckle would simply move back and forth on the threads, and not make a length difference. Look at a set of tie rods sometime. They're made the same way.

Jerry Owwww! I feel suitably chastised. Thank you for your input. Just remember, we have to design the things you break.

I ordered 1/4" Heim joints from Speedway and overlooked the LH thread as standard (RH needs to be specified). I like the trunbuckle idea though. Would give one a tad more adjustability than just the heims on each end and need for an exact measument on the rod length. Just requires some playing with.
What is a good pedal height for me to start at... approximates on the trucks originally? Fredico, what is the height of the 3600 that is to your liking?
