Chris, thank you SO MUCH for taking the time & effort to give us this lesson! I will try to make use of it...practice, practice, practice! I appreciate you sharing your knowledge with us! Would you advise use of clickable thumbnails as a good alternative? I have found a few people who couldn't see the thumbnails due to their firewall (maybe?), though. I made the mistake of compressing/resizing/resampling without keeping a copy of the original & then, when I wanted to make a large print I was unable to get a quality pic. :( Live & learn to SAVE your original elsewhere! ~Rosemarie

Since this Zama carb has NO primer bulb, I feel that old, swollen check valves in the MAIN NOZZLE and the IDLE circuit, may have been the contributing factor to the flooding; but Zama states it's flooding causes in regards to carbs with primer base assemblies on them. Even with lowered metering lever and new diaphragm and the mylar fuel pump (butyl rubber one pumps more)...flooding did occur. A test on the needle valve showed for the most part it was closing and opening properly (even though it was a USED needle valve). I probably should have got the RB kit, not the G & D kit. I will post one final time on this machine once the NEW carb is installed.

One of these, maybe? LASCO 17-6759 1/4-Inch Female Compression by 3/8-Inch Male Compression Brass Adapter Brasscraft 62-6-4X 3/8 OD by 1/4 OD Reducing Union Lead-Free, Rough Brass Carter Ice Maker Water Line Brass Tube Fitting, 3/8" Male x 1/4" Compression - (2 Pack)

See video below. Neighbors tecumseh mower engine hit rock, bent blade and sheered flywheel key. Replaced key and blade. Engine starts, but will only run a few seconds. Trying to diagnose I am curious if it is normal that the exhaust valve slightly opens at the beginning of the compression stroke. i attached a video of what I am seeing. Thank you for assisting Mark
