NEEDING HELP. champion blue ribbon 4.2 hp single cylinder all aluminum

[long johnson]

i found this old champion blue ribbon single cyl , non re-coil rope start motor the other day and it was completly seized but i was able to get it free , and its now nice and smooth with good compression , and it also didnt fire , so i cleaned up everything under the flywheel and its now getting good spark , i believe its ready to go, but im missing the high speed adjustment knob and i have no clue where to find it or even what im looking for, i dont know what to replace cause its not there , i took off the carb and took off the bowl where the missing adjustment screw was located and i cant even tell how it even controlled the adjustment of anything its under the float and outta reach of anything inside the carb ??? looking at the front of the motor , it is the bottom adjustment and its labled as high speed adjustment rich-lean can anyone help me figure out what i can do to figure out what the missing piece is? where to find another? im adding a few pics of the carb so u can see what im talking about ,thanks for the help

i was able to find an original repair parts kit for this carb on ebay used for 26.00, but it had the missing main adjustment screw (23) so i was happy to find it, it came with the original parts list and service instructions , i thought it may help someone else so here it is, i still need parts (26)main adjustment screw packing (27)main adjustment screw packing nut, but im sure ill be able to find a subsitute somewhere, anyways i installed the main adjustment screw and it fired right up... i only let it run for a about 30 secs beacause it seemed to be getting too warm on the shaft twards the motor , i will have to check it out tomorrow , see if i can find whats wrong if anything even is ????? if anyone has any suggestions of why it may be getting hot so fast please let me know

www.acmeoutboards.com has an owners manual on CD for that motor.

do you know what the thread size for the main adjustment screw gland which goes into the bottom of the bowl is? i found several kits which may be able to help you but the numbers cross reference over to briggs and stratton. that is if you still need the parts.

no i was able to find a original repair parts kit on ebay used , i took the gamble on the purchase, and luckly the adjustment screw i needed was included, i couldnt tell from the sellers pictures if it was there or not.. but it worked out well so far, i installed the screw and the motor runs!! lol but it is leeking gas around the screw so i still need part #0705 main adjustment screw packing(26 on the parts list) and part # 0703 main adjustment screw packing nut (27 on parts list) any help would be appreciated as always, thanks
