bean 85 #1 Posted July 18, 2013 (edited) I picked up a pull start, k series service engine, and have little info to go on. most of the tag is missing, I was able to scrub enough to make out the serial number. 6269816 looking at the chart, it looks like it was manufactured in 1974. would that make it a k181? were there k161s produced that late? not much to go on. carb number 41 053 32 also no help, that carb was used on both 7&8 hp. it has the thinner air filter. 1'1/4" 1-3/8", which is the replacement for the k161 . I don't know if pics will help. if they will, let me know. Edited July 19, 2013 by bean Share this post Link to post Share on other sites
bean 85 #2 Posted July 19, 2013 it appears to be a k161, solely based on the air cleaner. the carb that is on it, was used on both the k181 and k161. without the id plate, there is really no way to tell. the shaft is only 3" x 1", and not 3-1/4"x1" which has me thinking k161. it has been interesting research. it may come down to removing the head, to be 100% certain.

bean 85 #3 Posted July 21, 2013 (edited) after discovering the engine had a stuck intake valve, I removed the head. it is a 7hp k161. it seems, the previous owner let the engine sit outside for a while. the tank was in great shape, so I assumed it had been out of the weather. unfortunately, the carb was full of water. I had checked the engine oil, and it was clean. it may have been changed before selling. it has a bad coil/magneto, so I am not sure if I am going to go any further with it. if the crank case had water in it for a while, it may be asking for trouble. it does turn over easily. on the plus side, the tank is perfect, and the cylinder shows very little wear. no ridge at all. I think this was installed on an air compressor, probably on a service vehicle. I managedt to strip a few parts and repaint between rain and honey-do list Edited July 21, 2013 by bean Share this post Link to post Share on other sites
bean 85 #4 Posted July 22, 2013 my 7hp looks like it is dead. I can shine a light into the cylinder and see it getting egg shaped at the bottom, while turning the crank. the head had a pretty thick black deposit on it. probably smoking pretty good, when running. I have some good bits and pieces off of it. I would like to use the recoil parts to make a 70s k181 electric/recoil start Share this post Link to post Share on other sites
