37-89 bakelite caps??
#7

Texasrider: Thanks for the input.

I think my problem is with the RF choke part #11.
It was open and I had to put in a new one. Rather than take the old one out, I just connected the replacement choke in parallel with the original. Sloppy work I know!

I can affect the motorboating by placing my hand on the choke. So, I am going to see if I can get the original repaired and in it's original position.

Will post another item after I am finished with that.

Thanks again. Dick
