Last Sunday I posted having a throttle control issue...the response I got was:
It could be a carb issue Tim, but no need to buy new.
Could also be governor or linkage.
I know you said you checked for binding.
Disconnect the governor and run the carb by hand.
Do you get normal throttle response that way?
If not, maybe a carb issue. Throttle plate loose, etc
If you do, hook the governor back up and try running the
throttle by hand. Does the governor fight your efforts?
I unhooked the carb from the governor and it ran up and down with no problem...it seems to be reving a little high at full throttle, but I do not have a tach. When I would ease off on the throttle and take it down to idle, sometimes it acts like it is starving for gas and stalls. I tried adjust the idle screw up and down and the only time it doesn't stall is if the engine is idling really high.
I hooked the throttle back up to the governor and manually controlled the governor linkage. I did not note the governor fighting my efforts...it moves smoothly.
I hooked the governor back to the throttle handle linkage. The throttle goes from idle to full when I move the throttle handle 6 notches on the quardrant. When I pull the throttle handle to max there is no noticible increase in RPM.
Last, I did check the throttle to see if it is loose and it appears to be properly aligned on the throttle shaft and the screws are tight.
This behavior started after I put a brand new governor in. I did note that the arms on the new governor are in slightly different positions than on the old governor and the spring is much tighter.
Should the carb being going to full throttle so quickly? If so, does the additional pull on the governor beyond the carb being at full throttle there to keep the engine going under load?
Unfortunately I did not observe the behavior of my old governor linkage in relation to the new governor linkage...it seemed that I had more finite control over the engine RPM's.
Any suggestions would be helpful...I am truly stumped and figure that the fix will be simple.
