I made a copy of it using two large washers, held together with two pin-type things I got off an old chainsaw, and ground down the washers to the replica plastic one. I suppose if someone had a welder, it'd be a better way to make one, but I don't. I just laid the plastic pawl on the washer, traced it, and ground it. I drilled a hole for each pin and pounded them in and ground those where I needed them. That thing will last longer than the bike, I bet!

I think pvc would work pretty good too. What did you use for the pins? Maybe plastic rod just glued in? That would work.
I totally agree, it does not take opperator error for this part(pawl as I see it, do not know the actual part discription). Yes I used Pvc pins turned down in a lathe. The method that you described would be easier for me(as I have the equipment) but did not occur to me at the time. Welding the 5/16" nub and pins would have been easy. However I knew that BGF was sending me a replacemrnt part, so I just made it out of the first material that came to mind. I have pull starts on all my engines and just ordered another one. I do not always use them but they are there if I want too. As I remember the part that the pawl fits into is also plastic So as I always state when ever the pull start subject comes up, remember to hold that clutch in and avoid possiable trouble.
The days are getting longer and I am chomping at the bit. Got a good day Presidents day and got out for a cold but great 50 mi. ride with some other motorized bicycle riders!
