ok - what am i doing wrong here? throttle is very stiff - cant feather it at all- not rubbing anywhere - i've had three different springs mounted in three different locations - not enjoyable to drive - help!!
looks like maybe a linkage issue, looking at the rod end at the pedal bellcrank through the rod end at the carburetor it is almost in line with the throttle shaft... poor leverage action
After you figure out your spring location and force problem, I'd suggest using a dual spring (one inside the other) for safety reasons. Good Luck!
No spring problem,linkage set of wrong.you got linkage pulling back and up at the same time,needs to pull back only.
ok - thanks for the responses - forgive my next questions - 1: by fallwall do you mean firewall? 2: by bell crank do you mean the bit on the carb the linkage hooks into?
ok - i did my own research - learned a new term. i will try cutting the bell crank by thr firewall and extending it up a couple of inches. this should make the rod more parallel with the intake. i have a spare set up so no worries. thanks everybody.
Besides the other issues already mentioned the linkage position between the two carbs is going give you a "quick" throttle that would be hard to feather. If you moved the linkage to the larger holes on the carbs throttle arm that would improve the leverage ratio and give you a "softer" pedal. Mr Gasket has the bushings you would need for adapting the larger holes to fit your linkage.
Yes, what xracer40 said. ^ I don't think you are getting the leverage you need. Try moving the linkage on the carbs to the large holes above where you have them now. You will probably need to use a bushing for this.
ok - heres where i'm at. definate improvement. still a sharp throttle, but much smoother. disregard the wire holding the rod in place - on my way to get a small cotter pin. thanks all.
What he said. EDIT: (Didn't see the afternoon post before posting this, nice solution!) Probably due to the high rise location relative to the length of the pedal arm and fulcrum. Undo the push rod and raise it about an inch and push on it manually and see if that's easier. If it is I think you could probably extend the pedal arm an inch without messing with the ratios too much. Any more that about an inch and you will need to raise the pivot point and lengthen the pedal end too. The more you lenghten it above the pivot the harder but faster the pedal will be, but it won't bind as much at the start.
You need a spring in a spring for safety reasons. You don't want the horses to keep running when you let up on the gas pedal.......Keep it between the ditches. enjoy the ride
