mvvs 58 problem
 

hi,

i have an mvvs 58 and the black fuel inlet into the carb is blocking the access to the throttle arm.

how can i change the position of the fuel inlet a couple of degress. ive tied gently turning it but it wont budge.

thanks for any help.

...Wiz,


It would be helpful if you take a couple of digi-photos and post them here.

Most gas engine users would use, or fabricate a bell-crank, that would operate the throttle arm from a more accessible direction.

Dar is correct, look at the layout in this picture. It is easy to operate the throttle pushrod with a bellcrank

guys
i have built several gassers in my time and have never had to rely on a bellcrank to operate a throttle. this is my first mvvs and it seems to haunt this carby linkage setup.

i have always operated on the thinking that keep it simple routine and throwing a bellcrank in there is someting else to go wrong.
call me a weirdo if you will but i dont want a bellcrank to fail on my throttle linkage when i am torque rolling at 3 feet.

just my opinion.

when i work out a way for a straight linkage i will post pictures.

It is sound engineering to keep parts count as low as possible, and thus keep Murphy at bay. Nothing weird about that.
Please do post a picture when you are done.

well guys,

i have sorted out the whole linkage thing. it wasnt as hard as i first thought. egg on my face.
the 58 is a real gem of an engine. i cant understand why it took me soooo long to buy one.
outstanding performance. when its run in i will post figures.

i used to be a da man!

Looking good.
todo:
- fix those rod guide ends to the engine pod, so you will get precise lever movements
- Isolate the muffler heat from any tubing that runs near it
- Isolate the ignition from the engine heat, and provide for some cool air around that critical component.
