My 184 I use for mowing yard starting having a a problem about 3 weeks ago and this one has me stumped.It runs at higher speed like a tractor that needs time to warm up except the skipping never goes away. Tractor doesn't smoke and choke doesn't change anything. It becomes noticeable after about going past half throttle. Tractor eventually gets to where it has no power and can't be restarted until the next day. At first I thought maybe the points needed filing. After checking them out the tractor didn't run at all - found out I broke the prongs on the condenser wire putting it back together (tractor is a real pain to do anything inside the distributor). So points and condenser are new. Same problem with tractor. Thought maybe it was coil and some knowledgeable guys here thought so also and turns out that didn't help. Timing is good, lots of gas to carb. Had the carb off, looked clean, got carb cleaner through the passages. I'm wondering if the level of gas in the carb could too low and starving the engine could be the problem. I couldn't find the measurement for the float height- mine is a horseshoe design and all the numbers I found was for older carbs with a single bulb on the float and mine seems to need a different height.If someone has that and could pass it on I'd be thankful. Tractor has run great until now and nothing was changed on the carb other than cleaning since I've had it. I like mowing yard with it even though its like driving a tank - at least I'm not stiffened up when I get off unlike from riding on my lawn and garden tractor.
