Walbro 2-cycle carb model number + letter
I just pulled a Walbro WT-326C 2-cycle carb off my neighbor's non-working Stihl 020T chainsaw and have two quick questions.
First, what does the letter 'C' indicate at the end of the model number? I can find no data about this model WT-326C, but I can find info on WT-326 and WT-326-1.
Second, this carb only has only one adjustment needle. There are 2 holes labeled H and L, but one of these is plugged up. So is this the HIGH or LOW adjustment needle? Or is it some combination HIGH/LOW adjustment. I have not been able to find any information on a single needle 2-cycle carb so it is a bit perplexing to me.
Thanks for the help and advice!
