RE: Tower .75 Carb fit--Help
On my .75 there is also and o-ring or seal at the bottom of the hole the carb fits into. I believe I have the carb mashed down far enough to compress both. Other than flooding it three times and running it probably richer than necessary (per the instructions) it ran great.
Next time I'll fill the 24oz tank completely, get the high end needle fully adjusted, and I'll check the run time.
