That rod is more than straight enough. The problem I had was caused by a huge angle of about 30 degrees off center exerting a side pull at the bottom of the travel. The machine was on a pedestal table that positions the motor rather far away from the speed pedal. I have not experienced the slowdowns on machines mounted on standard industrial sewing machine tables.

Ok. Been 2 auto zone 3 times the last hour and a half trying to get the right belt. I decided to hold off going back only because my bobbin winder is suppose to come in tomoro... And from all the photos on Google of it attached the right way, it looks like the belt is what drives the winder to fill the bobbin. But I have the plate thing (left picture) and I can't figure out how to get that off! I took the screws on the handwheel out and tried pulling but nothing happens. I've seen 206s with that thing not on there, it also make it hard to get all these belts I keep trying on and off... Any help? Please

One more angle. What is this called, the belt guard?

Annoying little bugger.

Mounting the bobbin winder is the last thing to do. Ignore the bobbin winder when sizing and installing your drive belt.

Your belt length should be 2 x the centre to centre distance of the pulleys, plus 1/2 the circumference of the 2 pulleys. Position your motor about halfway in the adjustment range so you have space to install and adjust. The pulley size is the outside diameter of the pulley.

There's a screw in the center of the wheel(look from the outside) rightside, that is probably holding it on.

Tom, good to know that the winder should be last in my to do list!! Thx for that. Now as far as everything else u said, sounds like your speaking Mandarin. 2x this, circumference that, I don't get any of that unfortunately. But I'm determined to figure this out so... I will try and make sense of what you said. To be quite honest I do t know if the motor is in the right "adjustment range" or not. With no experience I don't have a clue how to figure that, so I will just be making adjustments until it's right! (See pic, yay or nay)?

Bob, I did remove that screw.. I removed all the removable screws from the handwheel and pieces surrounding it and there is no give. I mean I'm not sure how much harder I could pull. That seems like the only logical way to get that stupid piece off but as of now I can't get the wheel off to get to that part. Im gonna have to scour the web to find more articles and hopefully some videos on this. I also think my tension assembly isn't out on correctly so I'm gonna spend my whole day tomoro trying to get this thing running properly...

Looks like your adjustment is roughly centred.

For the simple math part, draw a sketch to scale and reread the instruction.

Lol! You could just do what I do. Take a bit string, put it round the two pulleys, just like the belt, then measure its length.

I can guarantee from personal experience, it is idiot proof. :-()
