I've actually run across one or two fuel filters with just enough resistance to flow so they do not allow for gravity feed. I have removed the fuel inlet hose, no flow. Cover the open tank filler neck with my mouth and blow in some pressure and get a trickle. Replace the filter with a different one and it works fine from then on.
Hard Start B&S 15hp industrial
Hi,
I own an old Scotts S1742 which I repowered with a B&S 15hp. It is not an Intek, it's an old Commercial & Industrial which came out of a Troybilt. The engine started and ran fine before I removed it from the Troybilt. Now that it is in my Scotts, it is hard to start. The engine needs to crank for about 30 seconds before the first ignition, and then another 30-45 seconds of cranking with intermittent sputtering before it will stay running. I need to start it at low idle, let it warm up for about 30 seconds, and then slowly bring the throttle up to operational speed.
- I tried adjusting/tightening the valves, it has made no difference.
- I tried tweaking the carburetor a few times. It is currently tuned well, but I have it running a smidgen on the rich side just to keep the engine from burning up.
- The choke is useless. If I try to use the choke, the engine simply will not start. I just leave the choke off.
- I believe the carb is the one which came with the engine, although I can't recall since I did the swap over a year ago.
- The troybilt had a choke which was separate from the throttle. The scotts had one of those setups where you could choke it by pushing the throttle all the way up. I couldn't really get it to work the same after swapping, so I installed a separate choke cable and lever, which I bolted onto the side of the steering column.
Once the engine is running, it runs very well. If the engine stalls while hot (e.g., running out of gas), then I have to set the idle low again to make it start, but it does not need to crank a lot like when it is cold.
Any ideas?
