Hi guys...hoping you can help.

Set up the Venture with OS 46 engine; have the mount set at the bottom of the holes in the frame with clutch pretty much alligned with the bottom of the bell housing; just like it says it should be.
All clearances seem to be fine & just usual " cog " noises but THEN!!
I turn it over with the starter shaft & then get what sounds like the clutch grinding on the top of the bell housing..not a harmonious sound.

I have no more travel in the frame holes to drop the engine etc. I really don't want to start elongating the holes in the frame as I believe this should not be necessary.

Any thoughts.
Eliminate loose bolts, loose anything else.
Regards....Noel

P.S. I have had an Ergo 30 I built from 200 parts & no problem.

If everything is at the right adjustment my only thought might be that there is too many threads sticking out past the nut holding the fan on and it is hitting the one way bearing in the clutch making the grinding noise when the motor is turned over.

you do have to elongat the holes because the shaft on the 46 is longer than the 32
the clutch will be about a 1/16 of an inch below the bell
hope this helps ya

There is a very fine line between 'hobby' and 'mental illness.'

Thanks all.

I don't think 1/16'' off the frame is going to do much harm; what to you think it might do to the warranty??

It is nice to be able ask questions here and get a prompt answer; beats on hold music.

Has been a very annoying fault 'cause it does not do it when assembled & checked but 2 starts & it sounds terrible.

Regards...Noel

just an idea, try grabing the little starting socket (where you put the starting shaft in sorry dont know the name off it ) and pull it up with your fingers then spin the main gear and see if it still makes a noise I noticed with my venture that when you install that start socket you have to pull the shaft right up before you tighten up the grup screw otherwise it is too low and you can hear what sounds like the clutch scratching . other than that i wouldnt have a clue
