Post, or send me, a few pictures of the carb, if you haven't already fully disassembled it. I can identify a commercially built carb. If the SR carb was manufactured in the mid- to late-80s, it can have Torx screws. However, many commercially built carbs also have Torx (or Phillips head) screws. The carb I pictured above is an SR carb - same number as yours - and it has the correct slotted fillister head screws.

The rebuild is going pretty well. I have the carb back together. I replaced the front vacuum choke pull off. While testing the front and rear pull-offs with a vacuum pump the front is fine, the rear does not pull in unless I block off the hole in it. No amount of vacuum will cause the pull off to operate with the vacuum applied unless the hole is blocked. I assume that the hole is there to bleed off the vacuum source once the pull off operates but it will not move at all with the hole open. Is the pull off defective?
